Martel Electronics 235 - Manual (Page 49)

An example would be the testing of a thermocouple transmitter. The
output CalPts would be setup for 0-25-50-75-100 percent and the zero
and full scale points entered. Next the input mA function would be
selected. Press SETUP and select the menu for InpRdg. Enter 4 as the
zero point and 20 as the full scale point.
Step through the CalPts using the INC key and observe the input
readings. The transmitter’s error in percent of scale will be the
observed reading minus the CalPts value. For example, if on the third
calibration point (50%) the input reads 50.15, the error is 0.15% of scale
(50.15-50.00).
