I bought 2 of these from Amazon, the back of the unit has XY-LJ02 . We need a replacement for out very old analog elapse time displace (kind of like a stop watch, the display runs while a signal is applied). After purchasing these items, they do not appear to do this, and if they can we can not figure how to get them to work.
So do you have product that would do what we need, are if this product would, could you describe how to set it up?
Thank you!
