secondary display starts flashing to indicate that the calibration is in
progress.
• Successful completion of the adjustment is indicated by a short beep
and the primary display briefly showing “PASS”.
• An adjustment failure is indicated by a long beep, the primary
display showing “FAiL” and a calibration error number appearing in
the upper secondary display. Correct the problem and repeat this
procedure.
8 Repeat step 3 through step 7 for each gain adjustment point shown in
Table 6- 5.
9 Verify the frequency gain adjustments using the “Frequency gain
verification test” on page 156.
Resistance gain adjustment procedure
Review the “Test Considerations” on page 140 and “Gain adjustment
considerations” on page 191 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 primary display will show the uncalibrated value and the upper
secondary display will show the reference value of the adjustment item.
3 Configure each adjustment item shown in Table 6- 6.

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.
