4. Measure the 10% full-scale output current and enter the value measured on the external
ammeter:
5. Measure the 90% full-scale output current and enter the value measured on the external
ammeter
6. Press the ENTER key to accept the calibration. Press the EXIT key four times to quit the

modes.
7. Verify the instrument’s output current calibration by setting up the loop test currents as
shown in Table 8 - 5 on page 50 and checking the set values against the ammeter standard.
