4. Close Spy Window.
Volts AC Accuracy Test 6-11.
Complete the following procedure to test the accuracy of the volts ac function for
both the 2640A and 2645A. Measurement accuracy applies to all channels, not
just the channel used for the test.
1. Configure Channel 1 for Volts AC In NetDAQ Logger, configure channel 1
for volts ac, 300 mV range. (See “Configuring Analog Channel Functions" in
Chapter 3 of this manual.)
2. Open Spy Window Select the Spy command from the Utilities menu. Select
channel 0101 (instrument 01, channel 01) from the Channel list. Click OK to
open the Spy window.
