Martel Electronics 235 - Manual (Page 52)

Select the type of thermocouple you will be using and press ENT. The
calibrator will prompt for the temperature unit to use.
Select the proper temperature unit and press ENT. The calibrator will
prompt for the desired output temperature in degrees.
Enter the desired temperature within the range of the selected
thermocouple and press ENT. If an incorrect or out of range value is
entered, the calibrator will display an error message and prompt again
for a value. Once a valid temperature is entered the calibrator will set
the output to the desired temperature. The display will reflect the
actual temperature being simulated at the terminals as the calibrator
adjusts its output to compensate for errors and drifts.
When the display indicates the selected temperature, the output is
properly set to simulate the requested thermocouple.
The top line of the display contains information about the simulation
being made.
The first three characters indicate the type of reference junction
compensation in effect.
Int = automatic compensation using the INTERNAL sensor.
Ext = automatic compensation using the EXTERNAL sensor.
Man = manual compensation.
Next is the single character thermocouple designation followed by the
temperature scale selected.
