and -200 mA dc adjustment points.
23. Push M on the 5720A.
24. Push M on the Product.
25. Write the values shown on the DMM in the Measured Current column of Table 5-7.
Calculate the average amplitude of the absolute positive and negative values as
given above.
26. Send the command: :CAL:ADJ? GAIN,2.00000,<calculated value>
27. Push S on the 5720A.
28. Push V on the Product.
29. Set the DMM to the ACV function and the 2V range.
30. Set the 5720A voltage output and frequency to the values in Table 5-7 for the 2 A
shunt and 2 V at 6 kHz adjustment point.
31. Push M on the 5720A.
32. Push M on the Product.
33. Write the value shown in the DMM in the Measured Current column of Table 5-7.
34. Send the command: :CAL:ADJ? FLAT,2.00000,<measured value>
35. Push S on the Product and the 5720A.
36. Connect the 20 A shunt between the Product output and the input of the DMM. See
Figure 5-2.
37. Set the DMM to the DCV function on the 1V range.
38. Set the DMM to Resolution 6.
39. Turn off all DMM Math functions.
40. After the DMM measurement settles, push the Offset key.
Note
The DMM must show a measurement between 0.000008 V and -0.000008 V.
41. Write in the DMM measurement in the measured error column in the Output Off
and 20A shunt row of Table 5-7.
42. Set the DMM ‘z’ store to the 20 A shunt resistance value.
43. Turn on the ‘÷z’ store on the DMM.
44. Set the 5720A output to the value in Table 5-7 for the 20 A shunt and 0 V dc
adjustment point.
45. Push M on the 5720A.
46. Push C on the Product.
47. Push V on the Product.
48. Push M on the Product.
49. Write the value shown on the DMM in the Measured Current column of Table 5-7.
50. Send the command: :CAL:ADJ? OFFS,0.00000,<measured value>
51. Set the 5720A output to the values in Table 5-7 for the 20 A shunt and 2 V dc and
-2 V dc adjustment points. Write the values shown on the DMM in the Measured
Error column of Table 5-7. Calculate the average amplitude of the absolute positive
