Operating Instructions
Read Thermocouple Sensors
Choose this function to measure temperatures with a thermocouple probe or
sensor.
Move the power switch
w
to READ then Double Click the EZ-DIAL knob to get
into the Double Click Menu. Turn the knob to scroll through the settings and
press the knob to make your selection. Select T/C for the FUNCTION, °F or °C
for the UNITS, T/C Type (J, K, T, E, R, S, B, N, G, C, D, L (J-DIN), U (T-DIN) or
P (Platinel II) and COLD JUNC ON or OFF (ON is the default).
Connect the PIE 820PM to the inputs of the device being calibrated using the
proper type of thermocouple wire via the miniature thermocouple socket. If no
sensor is connected, a wire is broken or the sensor is burned out, OPEN TC will
appear on the display. Signals above the maximum scale are limited by protection
circuitry with “OVER RANGE” on the display and the red OVERLOAD LED lit.
The PIE 820PM measures the input signal and constantly updates the display
with the current reading. Move the EZ-CHECK switch
