ADJUSTMENT PROCEDURE
This unit is calibrated at the factory to meet the ordered
specifications, therefore you usually do not need any cali-
bration.
Formatchingthesignaltoareceivinginstrumentorincase
ofregularcalibration,adjusttheoutputasexplainedinthe
following.
■HOW TO CALIBRATE THE OUTPUT SIGNAL
Use a signal source and measuring instruments of sufficient
accuracy level. Turn the power supply on and warm up for
morethan10minutes.
1) ZERO:Apply0%inputandadjustoutputto0%.
2) SPAN:Apply100%inputandadjustoutputto100%.
3) CheckZEROadjustmentagainwith0%input.
4) When ZERO value is changed, repeat the above proce-
dure1)–3).
MAINTENANCE
Regularcalibrationprocedureisexplainedbelow:
■CALIBRATION
Warmuptheunitforatleast10minutes.Apply0%,25%,
50%, 75% and 100% input signal.  Check that the output
signal for the respective input signal remains within accu-
racydescribedinthedatasheet.Whentheoutputisoutof
tolerance, recalibrate the unit according to the“ADJUST-
MENTPROCEDURE”explainedearlier.
CHECKING
1) Terminalwiring:Checkthatallcablesarecorrectlycon-
nected according to the connection diagram.
2)DIPSWsetting:Checkthattheswitchesaresettoap-
propriate positions.
3) Input:  Checkvoltageacrosstheterminal4–5witha
sensitive voltmeter.

 IftheRTDoritsextensionwiresarebroken,theoutput
goes over 100% (below 0% with downscale protection)
due to burnout function. Check leadwires in such a case.
4) Output:  Check that the loadis within the permissible
limit including wiring resistance.
