RTD Temperature Accuracy Test (Resistance) (2640A) 6-21.
The following RTD accuracy test applies to the 2640A and uses the 4-wire
connection (see Figure 6-4).
1. Connect the Decade Resistance Source to Channels 1 and 11 Remove the
Universal Input Module from the instrument and connect a cable from the
Decade Resistance Source to the Universal Input Module terminals for
channel 1 (Sense) and channel 11 (Source) as shown in Figure 6-4.
2. Configure Channel 1 for RTD-4W In NetDAQ Logger, configure channel 1
for RTD-4W, Fixed-385 range, with RTD R0 set to 100 Ohms. (See
“Configuring Analog Channel Functions" in Chapter 3 of this manual.)
3. Open Spy Window Select the Spy command from the Utilities menu. Select
analog channel 01. Click OK to open the Spy window.
4. Verify Accuracy Configure the Decade Resistance Source for the output
values below and verify the Spy window simulated temperature measurement
is between the minimum and maximum values.
