1.7.4 Calibration
Low, Mid and High Calibration Values
The Low calibration value compensates for offset while Mid compensates for span. These
values are set at the factory using an accurate millivolt reference. The following procedure
may be used if you want to calibrate each channel to a specific piece of thermocouple wire:
1. Change the equation number of the channel you want to calibrate to 38, and replace any
previous Low, Mid and High calibration values with zero (0). Make sure you have
