Do laser distance measurers give an option to zero out a reference point, like hitting the "tare" button on a weight scale?

I have an application where we need to know the difference in distance to a series of items from a previous reference, without having to trust some bozo's basic addition/subtraction skills. To visualize, think of boxes going down a conveyer belt, one a minute. Zero out distance to first box at 0.0". Next box might be +4.6" in relation to the first, then another follows at -2.9". This is intermittent use, not continuous production. Measurements can be manually read/written/recorded.
 
Hilti does not have that either. However it does display the last 4 measurements.
This is an older one but I don't think the new ones do either. You can add or subtract measurements.

Most of them have memory and add/subtract functions. Some of the Bosch, Stabila, Leica units have Bluetooth for export but I have never used that function and don't know how it works or what it can export to. Maybe there's an app that can do math for you, or you can just do simple math after export in Excel or whatever options the Bluetooth stuff might expose.

Hmm. Leica's DISTO Transfer software looks like the only one worth messing with. It actually sounds useful, based on the product literature.

I think they don't let you do a relative zero so you can't really screw up your measurements when you forget you did a relative zero. Save you from yourself, and all that....

I do a lot of real-time measurement with TOF (time of flight) laser rangefinders and triangulation lasers, but they all export a signal (analog, or Ethernet, or RS232/RS485 serial, or CAN/ProfiBus, etc) and then another device does useful things with that signal. That's the type of setup that would normally be used for what you're talking about (sounds like you already know that). The consumer grade all-in-one laser/display units for architects and construction people are just not intended for that type of function.

Thanks for all the help. I can see why they don't include it as a function.

Found out adafruit has a laser distance module for Arduino controllers for fifteen bucks, so we can cobble up something for the prototype.

If this works out, I'll be the next John D. Rockefeller. I'll try and remember you little people while I'm floating on my yacht in the isles.
 
Had to do that for work a few years ago. I was thinking full cavity search, nope they had me open the box they swabbed it and I was on my way.
