Volt Zero; Zero Ohm (Firmware V01.00 Only) - Fluke ScopeMeter 123 Service Manual

10. Connect the test tool to the 5500A as shown in Figure 5-7.
Figure 5-7. Volt Gain Calibration Input Connections 500V
11. Set the 5500A to supply a DC voltage of 500V.
12. Set the 5500A to operate (OPR).
13. Press
Gain DMM (CL0814) and Gain DMM (CL0815) will be calibrated now.
14. Wait until the display shows calibration status
15. Set the 5500A to 0V (zero) and to Standby.
16. Continue at Section 5.6.6.

5.6.6 Volt Zero
