AC Current Ranges 0.3 A, 3 A, 30 A Adjustment
Change the mode on the 5522A to ACI.
To adjust these ranges, see
Figure 34 :
1. Connect the 5522A to the Product output terminals.
2. Set the first current point to
300 mA 55 Hz low (30mA) and push the Select softkey.
3. Switch the output terminals ON. Set 30 mA ac 55 Hz on the 5522A. The Product reads the
approximate nominal value.
4. Push the Write softkey to save the new value.
5. Go through each of the current adjustment points in Table 11 . When finished, push the Exit
softkey to go to the basic calibration menu.
This completes this part of the adjustment.
