CHECKING
1) Terminal wiring: Check that all cables are correctly con-
nected according to the connection diagram.
2) Power input voltage: Check voltage supplied to the rack
(model: 10BX
q
). For the DC power source, be sure that
the ripple level is within 10% p-p.
3) Input: Check that the input signal is within 0 – 100% of
the full-scale.
4) Output: Check that the load resistance meets the described
specifications.
ADJUSTMENT PROCEDURE
This unit is calibrated at the factory to meet the ordered speci-
fications, therefore you usually do not need any calibration.
For matching the signal to a receiving instrument or in case
of regular calibration, adjust the output as explained in the
following.
n
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 procedure
1) – 3).
5) Go through the same procedure for Output 2. Extender
Card (model: 10EC) is required to access the Output 2
Adjustments on top of the unit maintaining electrical
connection at the rear connector.

Regular calibration procedure is explained below:
n
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 accuracy
described in the data sheet. When the output is out of toler
-
ance, recalibrate the unit according to the "ADJUSTMENT
PROCEDURE" explained earlier.
