B - Verification and Calibration
156
Steps 11-16 apply to Agilent 66309B/D output 2 only
13. Connect the external DMM (in voltage mode) directly to output 2.
Do not connect the load resistor or current shunt. Select output 2.
14. Press Shift Cal, scroll to CAL VOLT2, and press Enter.CAL:VOLT2
15. Press Shift Cal, scroll to CAL LEV, and press Enter to select the first
calibration point. CAL:LEV P1
16. Press Shift Cal, scroll to CAL DATA, press Enter Number, and enter the
voltage value displayed on the DMM. CAL:DATA 0.00
17. Press Shift Cal, scroll to CAL LEV, use É to scroll to P2 (the second
calibration point), and press Enter.CAL:LEV P2
18. Press Shift Cal, scroll to CAL DATA, press Enter Number, and enter the
second voltage value displayed on the DMM. CAL:DATA 0.00
Overvoltage Protection Calibration

19. Press Shift Cal, scroll to CAL VOLT PROT, and press Enter.CAL:VOLT:PROT
20. Wait for the dc source to compute the OVP calibration constant. The display
returns to Meter mode when the calculation is complete.
Current Programming and High-Range Measurement CalibrationNOTE: When performing a High Range current calibration, you must also calibrate the lowrange and the ac current measurement.

21. Connect the appropriate current monitor to output 1 as shown in figure B-1A.
Connect the DMM (in voltage mode) across the current shunt. Select o utp ut 1.
22. Press Shift Cal, scroll to CAL CURR, and press Enter.CAL:CURR
23. Press Shift Cal, scroll to CAL LEV, and press Enter to select the first
calibration point. CAL:LEV P1
24. Press Shift Cal and scroll to CAL DATA. Wait for the DMM reading to
stabilize. Then read the DMM and compute the first current value (DMM
reading ÷ shunt resistance). Press Enter Number and enter the first current
value in amperes.
CAL:DATA 0.00
25. Press Shift Cal, scroll to CAL LEV, use É to scroll to P2 (the second
calibration point), and press Enter.CAL:LEV P2
26. Press Shift Cal and scroll to CAL DATA. Wait for the DMM reading to
stabilize. Then read the DMM and compute the second current value (DMM
reading ÷ shunt resistance). Press Enter Number and enter the second current
value in amperes.
CAL:DATA 0.00
