Choose this function to measure temperatures with a
thermocouple probe, sensor or any device that output a
thermocouple signal.
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, E, T, R, S, B, N, L (J-DIN), U (T-DIN), G, C, D or
P (Platinel II)) and COLD JUNC ON or OFF (ON is the default).
Connect the PIE 850 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 OVERLOAD
LED blinks red.
The PIE 850 measures the input signal and constantly updates
the display with the current reading. Move the EZ-CHECK switch
q to MAX to see the highest reading and to MIN to see the
lowest reading. Press and hold the knob e to clear the MAX and
MIN readings.
