Meter calibration must be performed using a
thermocouple calibrator. If a millivolt source is used
instead, be sure to connect the output of the millivolt
source to an Omega MCJ Electronic Ice Point (or
equivalent) of the appropriate thermocouple type (or an
ice bath). Doing this will compensate for the cold junction
errors.
4.2 CALIBRATION PROCEDURE
Refer to Section 4.2.1 for details on how to calibrate the
meter using the Thermocouple Calibrator. Refer to Section
4.2.2 for details on how to calibrate the meter using the
Millivolt Source.
4.2.1 Thermocouple Calibrating
1.
Disconnect the power from the meter.
Remove the
front lens. Notice the the zero potentiometer (pot) is
located to the left of the display and the span
potentiometer is located to the right of the display.
Refer to
Figure 4-1
for the location of the calibration
pots.
