Fluke 7526A Calibration Manual page 29

To test the ohm input:
1. Apply a four-wire short to the Product 4W RTD/Ω input.
2. For the first test, set the Product to the 400 Ω range.
3. For the second test, connect the Product 4W RTD/Ω input to the output of the 5522A
as shown in Figure 8.
4. Set the Product to the 400 Ω range. Note the indication in Table 8.
5. Set the Product to the 4000 Ω range after the 400 Ω test. Note the indication in
Table 8.
6. Output the same nominal values and note the Product indication in the 7526A
Reading column of Table 8.
7. Subtract the 5522A Actual Value from the 7526A Reading and ensure that it is
within the specified tolerance.
