11. Set the 5500A to supply a DC voltage of 500V.
12. Set the 5500A to operate (OPR).
13. Press
to start the calibration.
Gain DMM (CL0814) and Gain DMM (CL0815) will be calibrated now.
14. Wait until the display shows calibration status
Gain DMM (CL0815):READY.
15. Set the 5500A to 0V (zero) and to Standby.
16. Continue at Section 5.6.4.
5.6.4 Volt Zero
Proceed as follows to do the Volt Zero calibration:
1. Press
to select calibration adjustment step Volt Zero (CL 0820):IDLE.
2. Terminate Input 1 and Input 2 with the BB120 and a 50Ω or lower termination.
3. Press
to start the zero calibration of all mV/d settings (CL0820...CL0835)
4. Wait until the display shows
Volt Zero (CL 0835):READY.
5. Remove the 50Ω termination from the inputs.
6. Continue at Section 5.6.5.
5.6.5 Gain Ohm
Proceed as follows to do the Gain Ohm calibration:
1. Press
to select calibration adjustment step Gain Ohm (CL 0860):IDLE
2. Connect the UUT to the 5500A as shown in Figure 5-7.
Notice that the sense leads must be connected directly to the test tool.
