Resistance gain adjustment procedure
Review the “Test Considerations” on page 25 and “Gain adjustment
considerations” on page 77 sections before beginning this procedure.
This procedure adjusts the gain for the two-wire resistance function. The gain for
the 100 MΩ range is derived from the 10 MΩ range and does not have a separate
adjustment point.
1 Press [] to enter the resistance gain calibration.
2 The display shows the uncalibrated value and the reference value of the
adjustment item.
3 Configure each adjustment item shown in Table 1-27.
4 Use or to select the adjustment item.
5 Apply the input signal shown in the “Input” column of Table 1-27.
6 Enter the actual applied input.
7 Press to start the adjustment. The word CALib starts flashing to indicate
that the calibration is in progress.
– Successful completion of the adjustment is indicated by a short beep and
the display briefly showing PASS.
– An adjustment failure is indicated by a long beep, the display showing FAiL
along with a calibration error number. Correct the problem and repeat this
procedure.
8 Repeat step 3 through step 7 for each gain adjustment point shown in
Table 1-27.
If the zero offset adjustment procedure has been recently performed prior to the
resistance gain calibration procedure, the adjustment items “Short” and “OPEn”
can be omitted.
Always complete tests in the same order as shown in Table 1-27.
