When RJ Sensor Is Used (Making Use of Refer-
ence Junction Compensation)
To calibrate a device with built-in reference junction temperature com-
pensation by sourcing a thermoelectromotive force with the calibrator
without using any external 0
°
C reference junction compensation
means, use the optional RJ sensor (P/N: B9108WA).
Step 1: Insert the RJ sensor into the R.J.INPUT connector of the cali-
brator. Insert the sensor until the locking claw in the bottom of
the sensor connector locks with a click. To unplug the sensor
connector, unlock the connector by gently pushing the locking
claw.
Step 2: Using the function selector switch, select
.
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 de-
fault value (600
°
C for a type-B thermocouple).
