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
.
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.
