Chapter 3 Calibration Procedures

General Calibration/Adjustment Procedure

If the calibration fails, a ‘‘OVP CAL FAIL’’ message appears for one second and the display shows the ‘‘CAL SETUP 2’’ for OVP calibration again.

13Select the low current calibration point. (‘‘I LO 0.200 A’’ - E3634A model)

I LO 0.500 A (E3633A)

The display shows the low current calibration point.

14Read the DVM and change the low current value on the display to match the computed current (DVM reading ¸ by shunt resistance).

For example, if the computed value is 0.499 A, adjust the current to 0.499 A using the knob and arrow keys.

Notice that you should wait for the DVM reading to stabilize for accurate calibration.

I LO 0.499 A

15Pressing the ‘‘Calibrate’’ key saves the change and selects the middle current calibration point. (‘‘I MI 3.500 A’’ - E3634A model)

I MI 10.000 A (E3633A)

If the entered number is within an acceptable range, an ‘‘ENTERED’’ message appears for one second. If the entered number is not correct, an ‘‘MIN VALUE’’ or ‘‘MAX VALUE’’ message appears for one second and the display shows the low current calibration point again. The display now shows the middle current calibration point.

16Read the DVM and change the middle current value on the display to match the computed current (DVM reading ¸ by shunt resistance).

For example, if the computed value is 9.999 A, adjust the current to 9.999 A using the knob and arrow keys.

Notice that you should wait for the DVM reading to stabilize for accurate calibration.
