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).
