Analog Channel Integrity Test 6-13.
Complete the following procedure to test the integrity of each analog channel (2
to 20) to verify each analog channel is capable of making measurements.
1. Configure Channel for Ohms In NetDAQ Logger, configure channels 2
(then 3, then 4, etc. as this step is repeated) to 20 for Ohms-2W, 300 range
[2640A] or 30K range [2645A]. (See “Configuring Analog Channel
Functions" in Chapter 3 of this manual.)
2. Connect Test Leads Remove the Universal Input Module from the
instrument, disconnect the test leads and connect them to the channel under
test (starting with channel 2). Reinstall the Universal Input Module in the
instrument.
3. Open Spy Window Select the Spy command from the Utilities menu. Select
the analog channel under test. Click OK to open the Spy window.
4. Verify Reading Alternately open and short the test leads observing the
measurement for the analog channel under test in the Spy window shows
Overload for opened leads and very low resistance for shorted leads (less than
10 ohms for the 2640A, or less than 1k ohms for the 2645A).
5. Repeat Test for each Channel Repeat steps 2 to 4 for each channel (3, 4, 5,
and so forth to channel 20).
Computed Channel Integrity Test 6-14.
Complete the following procedure to test the integrity of each computed channel
(21 to 30) to verify each computed channel is capable of making measurements.
1. Configure Channels 1 and 2 for Ohms In NetDAQ Logger, configure
channels 1 and 2 for Ohms-2W, 30k range. (See “Configuring Analog
Channel Functions" in Chapter 3 of this manual)
2. Configure Channel for Average In NetDAQ Logger, configure channels 21
to 30 for ChanA - ChanB (Difference) with the difference channels being
analog channel 1 and analog channel 2. (See "Configuring Computed Channel
Functions" in Chapter 3 of this manual.)
3. Connect Test Leads Remove the Universal Input Module from the
instrument and connect test leads to channels 1 and 2. Reinstall the Universal
Input Module in the instrument.
4. Open Spy Window Select the Spy command from the Utilities menu. Select
the computed channels 21 to 28. Click OK to open the Spy window.
5. Verify Reading Alternately open and short both sets of test leads observing
the measurement for the computed channel under test in the Spy window
shows +Overload for opened leads and very low resistance for shorted leads.
6. Repeat Test Repeat steps 4 to 5 for channels 29 and 30.
