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 thermocouple.
The thermoelectromotive force is sourced with reference to 0°C.
Step 1:
Using the function selector switch, select
100mV TC
.
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 default 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-circuited.
