Step 3:
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 4:
When the RJ sensor is connected, the calibrator goes into
the RJ ON status and the
RJON
symbol appears on the LCD
Step 5:
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 6:
Pressing the
key causes the
indicator on
the LCD to change from
to .
A thermoelectromotive force based on the temperature
detected by the RJ sensor develops between the output
terminals.
Step 7:
To turn off the output, press the
key once again.
The
appears on the LCD and the output terminals are
open-circuited.
NOTE
• When you have attached the RJ sensor to the device being calibrated,
wait until the detected temperature stabilizes before you begin using
the calibrator.
• If no reference junction compensation is required, be sure to remove
the RJ sensor from the calibrator.
