4.4.2 When No RJ Sensor Is Used
From the output terminals, the calibrator sources a thermoelectromotive
force corresponding to the preset temperature of a selected thermo-
couple. The thermoelectromotive force is sourced with reference to
0
°
C.
Step 1: Using the function selector switch, select .
Step 2: Using the key, select the type of thermocouple. Select
the type from K, J, E, T, R, B, S, N, L and U. The selected
type of thermocouple is shown on the LCD.
Step 3: Set the output value digit by digit using each pair of and
output setting keys.
Each pair of
and keys corresponds to each digit of the
LCD reading. Each press of the or key increases or
decreases the digit. Increasing the digit from 9 or decreasing
it from 0 causes the digit to overflow or underflow, allowing
you to set the output value without interruption. Holding down
the
or key continuously changes the digit in question.
Pressing the key initializes the output setpoint to the de-
fault value (600
°
C for a type-B thermocouple).
Step 4: Pressing the key causes the indicator on the LCD
to change from to . A thermoelectromotive force (mV)
equivalent to the preset temperature develops between the
output terminals.
Step 5: To turn off the output, press the key once again. The
appears on the LCD and the output terminals are open-cir-
cuited.
