Have you tried contacting Bell with the model # of your item and
asking them how to do it?


I wrote that I did that.


Well he says that he contacted them years ago and they said it can't be
done. Not sure what the point of this thread is then...


The point is this: Customer service employees do not always know
enough about the technology and there may be a method that works that
someone here has discovered. Seems there isn't, but why not ask?


I don't know. I'd just google it. Some people seem to have your
question but no one has found an answer.

Looking at the manual available online:

https://www.manualslib.com/manual/88...?page=6#manual


When it says on page 6: "Total distance traveled is indicated by "ODO"
and displayed on the bottom line. To reset ODO, press both RIGHT and
LEFT buttons for 3 seconds or remove and replace the battery. Now press
the RIGHT button to advance to the DST mode"

This seems like the only reference to the ODO in the manual. It only
tells you how to reset the ODO. Not how to set it.


This is the manual that gets shipped with the device:

https://www.scribd.com/document/3191...ard-100-Manual

It says on page 4, quote "Note: Replacing the battery will erase all
stored information. When installing a new battery after having used the
computer, make sure to write down the odometer value before changing the
battery so you can later re-enter it in the computer".

There is no instruction anywhere how to actually enter that value.


Yeah, you're right. I would not purchase anything from these guys.

In one of the on line discussions somebody wrote, "well, it works
pretty good for a item that costs less then twelve dollars" :-)


It actually does. What impressed me, for example, was that it remained
completely function with a battery that I forgot to swap and that had
dropped from 1.5V to 1.15V. The LCD became a bit dim, that's all.

It's just that, obviously, their spec writers and SW designers have
botched part of their job.

messed-up commercial designs. On the bikes I already
had to do that for lighting but there it was a
necessity.

If I ever build my own it will be like what cars have
since over 100 years. A speedometer that is backlit at
night, works off the central battery and most of all
never forgets its odometer info.

I think that he was suggesting that you pulse the meter
until it reaches the mileage you originally had.


Yes, I misunderstood Graham. If almost all brands contain
Reed switches like Andrew said that might not be so great
for the lifetime of that switch. Also, it would eat up
battery because there will be a limit in the speed and I
guess that's not the same at on a Ferrari Testarossa. So
I'd have to let that artificial wheel run a long time in
order to get the usual 4000+ miles back in, and next time
8000+, then 12000+ and so on. Most likely that takes
weeks.

-- Regards, Joerg

http://www.analogconsultants.com/

It looks like you still have not got it. Lets forget the
grinder idea as I agree with Andrew about the read switches
and that does tend to rule that idea out. My first idea was
to do it electronically with a simple circuit that would send
relatively high frequency pulses to the appropriate terminals
on the head unit to simulate the action of the switch. From
your decription of your background surely this is a trivial
exercise and I am sure you will have the required circuit
components lying around on your bench. See my earlier posts
as to how long it would take at different frquency pulsing if
you set the tyre circumference to 9999mm. 4000 miles would
take around 180 hours at 1Hz, 18 hours at 10Hz etc and my
guess is that the head unit circuit should at least cope with
that. Any higher frequecy response would be a bonus.


Yeah, I could hack the cable aoart, roach on a MOSFET, wrap
the whole enchilade with duct take and feed pulses from a
function generator :-)
[snip]

Why so dramatic do you just like cludging things with duct tape.
Your head unit has two contacts on the back and my guess is that
if you apply a rapid series of shorts across those two contacts
the unit will display speed. How you might choose to apply those
shorts is up to you: electronically, mechanically eg make a
simple rotary switch driven by an electric drill or even a DPDT
relay wired to self oscillate. The possibilities are almost
endless, relatively simple and do not involve cable hacks and
duct tape cludges


I could probably do that but I am sure they have a lowpass filter
in there to mitigate noise and Reed bounce. Or I could pipe out the
power supply to some metal spots such as a couple of the mounting
screws and supply 1.5V while changing the battery. That way it
won't forget the mileage.

OK I give in. I am largely just a lurker in this group and only chip
in when things look like they are, as one might say, "tech". If you
are the "elecy techy" you claim to be then you could have solved this
problem without even troubling this news group. The reply above shows
that you know how to solve this problem so why waste bandwith?


sigh

Again, the reason for my question is this simple:

1. The manual says you can re-enter the mileage number (without tricks
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^

such as clocking in the equivalent of thousands of miles which slurps
away a lot of juice from the newly installed battery).

2. The customer service says that it cannot be re-entered.

These statements clearly contradict each other. I simply wanted to know
which statement is correct and whether someone else had managed to
re-enter the odometer number, and most of all how.

I can't comment on Bell meters but on other makes, including a very
cheap Chinese meter, if the manual told you that you COULD re-enter
the mileage then it also told you HOW to re-enter the mileage.

What is it that I keep hearing repeated? RTFM?


Read and show us whe

https://www.scribd.com/document/3191...ard-100-Manual

Certainly Sir.

In the section labeled "Additional Function Modes", the first item
reads:
ODOMETER (ODO) - Total distance traveled is indicated by "ODO" and
displayed on the bottom line. To reset ODO, press both RIGHT and LEFT
buttons for 3 seconds or remove and replace the battery.


Wrong. I have underlined it above in the thread. This is about
_entering_ and not about erasing.

You're confusing reset and set. It's telling you how to reset it to 0.
Not how to set it back to whatever it was. The choice of the word reset
may be confusing but in context it's clear.

And in the context of the entire manual there is no method of
re-entering the previously recorded mileage mentioned although you
seem vehement on insisting that there must be..

You CAN re-enter the mileage in the computer after changing the battery. I found the instructions on the internet (Google translated from Chinese): (1) pry open plastic battery cap, (2) on the inside of battery cap, scratch total mileage number with sharp pin, (3) change battery, (4) replace cap. Prior mileage is now in computer. Add that mileage to number shown on screen. You like really much our computer. You thank. The Bell Company.

had to do that for lighting but there it was a
necessity.

If I ever build my own it will be like what cars have
since over 100 years. A speedometer that is backlit at
night, works off the central battery and most of all
never forgets its odometer info.

I think that he was suggesting that you pulse the meter
until it reaches the mileage you originally had.


Yes, I misunderstood Graham. If almost all brands contain
Reed switches like Andrew said that might not be so great
for the lifetime of that switch. Also, it would eat up
battery because there will be a limit in the speed and I
guess that's not the same at on a Ferrari Testarossa. So
I'd have to let that artificial wheel run a long time in
order to get the usual 4000+ miles back in, and next time
8000+, then 12000+ and so on. Most likely that takes
weeks.

It looks like you still have not got it. Lets forget the
grinder idea as I agree with Andrew about the read switches
and that does tend to rule that idea out. My first idea was
to do it electronically with a simple circuit that would send
relatively high frequency pulses to the appropriate terminals
on the head unit to simulate the action of the switch. From
your decription of your background surely this is a trivial
exercise and I am sure you will have the required circuit
components lying around on your bench. See my earlier posts
as to how long it would take at different frquency pulsing if
you set the tyre circumference to 9999mm. 4000 miles would
take around 180 hours at 1Hz, 18 hours at 10Hz etc and my
guess is that the head unit circuit should at least cope with
that. Any higher frequecy response would be a bonus.


Yeah, I could hack the cable aoart, roach on a MOSFET, wrap
the whole enchilade with duct take and feed pulses from a
function generator :-)
[snip]

Why so dramatic do you just like cludging things with duct tape.
Your head unit has two contacts on the back and my guess is that
if you apply a rapid series of shorts across those two contacts
the unit will display speed. How you might choose to apply those
shorts is up to you: electronically, mechanically eg make a
simple rotary switch driven by an electric drill or even a DPDT
relay wired to self oscillate. The possibilities are almost
endless, relatively simple and do not involve cable hacks and
duct tape cludges


I could probably do that but I am sure they have a lowpass filter
in there to mitigate noise and Reed bounce. Or I could pipe out the
power supply to some metal spots such as a couple of the mounting
screws and supply 1.5V while changing the battery. That way it
won't forget the mileage.

OK I give in. I am largely just a lurker in this group and only chip
in when things look like they are, as one might say, "tech". If you
are the "elecy techy" you claim to be then you could have solved this
problem without even troubling this news group. The reply above shows
that you know how to solve this problem so why waste bandwith?


sigh

Again, the reason for my question is this simple:

1. The manual says you can re-enter the mileage number (without tricks
such as clocking in the equivalent of thousands of miles which slurps
away a lot of juice from the newly installed battery).

2. The customer service says that it cannot be re-entered.

These statements clearly contradict each other. I simply wanted to know
which statement is correct and whether someone else had managed to
re-enter the odometer number, and most of all how.

I can't comment on Bell meters but on other makes, including a very
cheap Chinese meter, if the manual told you that you COULD re-enter
the mileage then it also told you HOW to re-enter the mileage.

What is it that I keep hearing repeated? RTFM?


Read and show us whe

https://www.scribd.com/document/3191...ard-100-Manual

Certainly Sir.

In the section labeled "Additional Function Modes", the first item
reads:
ODOMETER (ODO) - Total distance traveled is indicated by "ODO" and
displayed on the bottom line. To reset ODO, press both RIGHT and LEFT
buttons for 3 seconds or remove and replace the battery.

You're confusing reset and set. It's telling you how to reset it to 0.
Not how to set it back to whatever it was. The choice of the word reset
may be confusing but in context it's clear.

And in the context of the entire manual there is no method of
re-entering the previously recorded mileage mentioned although you
seem vehement on insisting that there must be..

You're replying to the wrong guy. I posted that saying there wasn't
anything in the manual about putting any value but 0.

Have you tried contacting Bell with the model # of your item and
asking them how to do it?


I wrote that I did that.


Well he says that he contacted them years ago and they said it can't be
done. Not sure what the point of this thread is then...


The point is this: Customer service employees do not always know
enough about the technology and there may be a method that works that
someone here has discovered. Seems there isn't, but why not ask?


I don't know. I'd just google it. Some people seem to have your
question but no one has found an answer.

Looking at the manual available online:

https://www.manualslib.com/manual/88...?page=6#manual


When it says on page 6: "Total distance traveled is indicated by "ODO"
and displayed on the bottom line. To reset ODO, press both RIGHT and
LEFT buttons for 3 seconds or remove and replace the battery. Now press
the RIGHT button to advance to the DST mode"

This seems like the only reference to the ODO in the manual. It only
tells you how to reset the ODO. Not how to set it.


This is the manual that gets shipped with the device:

https://www.scribd.com/document/3191...ard-100-Manual

It says on page 4, quote "Note: Replacing the battery will erase all
stored information. When installing a new battery after having used the
computer, make sure to write down the odometer value before changing the
battery so you can later re-enter it in the computer".

There is no instruction anywhere how to actually enter that value.


Yeah, you're right. I would not purchase anything from these guys.

In one of the on line discussions somebody wrote, "well, it works
pretty good for a item that costs less then twelve dollars" :-)


It actually does. What impressed me, for example, was that it remained
completely function with a battery that I forgot to swap and that had
dropped from 1.5V to 1.15V. The LCD became a bit dim, that's all.

It's just that, obviously, their spec writers and SW designers have
botched part of their job.

Not really as you have purchased the item. Which of course means that
they have accomplished what they set out to do.... sell cheap bike
meters.

Even a limited review of the meters in discussion groups on the Net
seems to show that (1) no one has managed to re-enter the Odo meter
numbers, and (2) as they are cheap meters no one seems to be
complaining.

Well except for one guy.

You CAN re-enter the mileage in the computer after changing the battery. I found the instructions on the internet (Google translated from Chinese): (1) pry open plastic battery cap, (2) on the inside of battery cap, scratch total mileage number with sharp pin, (3) change battery, (4) replace cap. Prior mileage is now in computer. Add that mileage to number shown on screen. You like really much our computer. You thank. The Bell Company.

I'd guess that for those that do not have a pin one could write the
original figure on small piece of paper and stick it on the handle bar
with double back tape :-(

Another problem. In this Modern Information Oriented Era do people
actually have pins? Are pins even legal to possess? After all, Great
Aunt Harriet's weapon of last resort was a hat pin.
