Volts DC Accuracy Test (PAI Module)
For these tests you must move between the Fluke DAQ Configuration dialog and the
Communications dialog. Use the Configuration dialog to set up the analog module
channels. Use the Spy option of Communications dialog to view the measurements. All
testing is done with channel 1.
The following procedure tests the accuracy of the volts dc function for each PAI module
in the device. Measurement accuracy applies to all channels, not just the channel used for
the test.
1. Configure Channel 1 for V dc Using the Fluke DAQ software, configure the PAI
channel 1 for V dc, 90 mV range.
2. Open Spy Open the Spy window under the Configuration dialog. Select channel 1
for each PAI module you want to test.
3. Verify Accuracy Configure the 5700A for the output values below and verify the
measurement is between the minimum and maximum values. Change the channel 1
range as required (see Step 1).
