DAQM907A Analog Sense Inputs Verification (Optional)
This procedure is used to check the calibration of the analog sense inputs
(Channel 06 and 07) on the DAQM907A.
1 Remove connections in previous test and make connections to Channel 04 and
05 as shown below:
A wire is not needed to short Channel 04 GND to Channel 05 GND because
they are already shorted on board.
2 Set the following voltage and current outputs for Channel 04 and 05. Compare
the measurement results of Channel 06 and 07 to the appropriate test limits
shown in the table below.
