"rJ" - COLD JUNCTION COMPENSATION
CHECK
The "rJ" code and the temperature, in tenths of
°C, measured by the CJ compensator are
shown alternately on the display.
1) Make sure that the cold junction temperature
measured by the controller is equal to the value
measured by the measuring device.
2) Push FUNC pushbutton, the instrument will go
to the next calibration parameter.
TC Calibration only:
Thermocouple calibration is now complete, if RTD
calibration is not needed, press FUNC until "CAL"
is displayed see step 5 at page 21
RTD INPUT CALIBRATION
"PL" - RTD INPUT - INITIAL SCALE VALUE
The display will show "PL.F" (where "F" means
"OFF").
1) Connect a resistor box as shown in fig. 14.
Fig.14
2) Set 0.00
W
on the resistor box.
3) Push
▲
or
▼
pushbutton, the display will
change to "PL.n" (where "n" means "On").
4) After 30 seconds, start the calibration by
pushing the FUNC pushbutton. Only the
decimal point of the last significant digit will light
to indicate that the controller is performing the
calibration routine. At the end of this calibration
routine, the controller will go to the next
parameter.
"PH" - RTD INPUT - FULL SCALE VALUE
The display will show "PH.F" (where "F" means
"OFF").
1) Set the resistor box to 300.00
W
.
3) Push
▲
or
▼
pushbutton, the display will
change to "PH.n" (where "n" means "On").
4) After 30 seconds, start the calibration by
pushing the FUNC pushbutton. Only the
decimal point of the last significant digit will light
to indicate that the controller is performing the
calibration routine.
At the end of this calibration routine, the
instrument will go to the next step.
"P." - RTD INPUT CHECK
The "P." code followed by the two most
significant digits and the remaining digits of the
measured value are shown alternately on the
display.
