at the PC. Source five calibration points from the 5522A:
•
0 mA
•
13 mA
•
26 mA
•
39 mA
•
52mA
For each calibration point adjust the current for the maximum accuracy with the DMM
indication as feedback. Push ENTER on the PC when stable to go to the next calibration
point.
Step 16: 10 V Read Adjustment
Connect 5522A V source jacks to 7526A isolated jacks. Use the 8508A DMM to monitor
the voltage.
Enter
16
on the PC. Source three calibration points from the 5522A:
•
0 V
•
5 V
•
10 V
For each calibration point, adjust the voltage for the maximum accuracy. Use the DMM
indication as feedback. Push ENTER on the PC when stable to go to the next calibration
point. See Table 3 for the test equipment used for this procedure. See Figure 17 for the
connections.
