Calibration Check

1.Connect the UPS-III-IS to the electrical calibrator. Switch on
the electrical calibrator and allow it to thermally stabilise.
2.Switch on the UPS-III-IS and allow the instrument to thermally
stabilise.
3.Set the UPS-III-IS to mA measure, adjust the electrical
calibrator to apply the first value in the table 3. Record the
reading of the UPS-III-IS.
4.Repeat step 3 for all the values in the table 3.
5.Compare the recorded values and the applied values if the
difference is greater than the permitted error, the instrument
requires a calibration adjustment.
6.Repeat this procedure for V measure (table 4) and mA source
(table 5).

Calibration Adjustment

1.Connect the UPS-III-IS to the electrical calibrator. Switch on
the electrical calibrator and allow it to thermally stabilise.
