4. Close Spy Window.
Volts DC Accuracy Test (2645A) 6-10.
Complete the following procedure to test the accuracy of the volts dc function for
the 2645A. Measurement accuracy applies to all channels, not just the channel
used for the test.
1. Configure Channel 1 for Volts DC In NetDAQ Logger, configure channel 1
for volts dc, 90 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.
