Calibration of RS Telephone Tester Model - 43-114

Does anyone know if there is a way to calibrate this tester..

After professional calibration of my dials, my tester is displaying 1 to 2 numbers higher than the numbers that work on my landline.

Thanks a lot,
Gary

There is a topic on here that states the manual is in the TCI library.

Thanks Harry,

I couldn't get that link to work but I found another one with Google and there is nothing  mentioned about calibration.  I thought there might be a way to calibrate that isn't in the manual.

Thanks,
Gary

We probably need to find a shop manual for calibration info.

Here's a current search link to the owner's manual and schematic:

Thanks Paul.  That is the version I found, but I'm not seeing anything about setting or calibrating the tester.
