Steps 27-32 apply to Agilent 66309B/D output 2 only
27. Connect the appropriate current monitor to output 2 as shown in figure B-1A.
Connect the DMM (in voltage mode) across the current shunt. Select output 2.
28. Press Shift Cal, scroll to CAL CURR2, and press Enter.
29. Press Shift Cal, scroll to CAL LEV, and press Enter to select the first
calibration point.
30. 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.
Press Shift Cal, scroll to CAL LEV, use É to scroll to P2 (the second
31.
calibration point), and press Enter.
32. 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.
Low-Range Current Measurement Calibration (applies to Agilent 66311B/D, 66309B/D output 1
only)
Action
33 Disconnect all loads from the dc source but leave the sense jumpers in
place. Do not connect any equipment to the output until after step #34.
34. Press Shift Cal, scroll to CAL CURR MEAS LOW, and press Enter.
35. Connect the 800 ohm calibration load resistor to output 1 as shown in
figure B-1B. Connect the external DMM (in current mode) in series with
the load.
36. Press Shift Cal, scroll to CAL LEV, and press Enter to select the first
calibration point.
37. Press Shift Cal and scroll to CAL DATA. Wait for the DMM reading to
stabilize. Press Enter Number and enter the current reading displayed on
the DMM in amperes.
AC Current Measurement Calibration (applies to Agilent 66311B/D, 66309B/D output 1 only)
Action
38.
Disconnect all loads from the dc source but leave the sense jumpers in
place.
39. Press Shift Cal and scroll to CAL CURR MEAS AC, and press Enter.
40. Wait for the dc source to compute the ac current calibration constant. The
display returns to Meter mode when the calculation is complete.
