14.7.2 Common Problems and Solutions
Analog Output Incorrect
Make certain of the type of Analog Output (voltage or current)
that the channel is equipped with; see “Identifying the Output
Type” on page 68.
Use the DIAGNOSTICS -> DAC FULL SCALE and DIAGNOSTICS -> DAC
ZERO SCALE menu items to force the Analog Output to a known
output. Then, adjust your readout device, panel meter, PLC or
data acquisition system to match.
Check the output selection jumpers; see “Output Selection” on
page 68.
Check the “DAC SETUP -> DAC. ZERO-SCALE” and “DAC SETUP ->
DAC FULL-SCALE” menu items.
Sensitivity to EMI/RFI
To obtain maximum immunity to electromagnetic or radio fre-
quency interference, make certain that the shield of the cable is
connected to ground/earth only at the readout device. The shield
of the cable should not be connected to the instrument.
