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.
