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
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 5.6.6.
5.6.6 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 A and Input B 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 terminations from the inputs.
6. Continue at Section 5.6.8. (For firmware version V01.00 continue at Section 5.6.7).
5.6.7 Zero Ohm (firmware V01.00 only)
Proceed as follows to do the Zero Ohm calibration:
1. Press
to select calibration adjustment step Zero Ohm (CL 0840):IDLE
2. Make a short circuit between the Input A banana socket and the COM input .
3. Press
to start the Ohm Zero calibration of all ranges (CL 0840...CL 0846).
4. Wait until the display shows the calibration status
Zero Ohm (CL 0846):READY.
5. Remove the Input A to COM short.
6. Continue at Section 5.6.8.
