Adjusting the Current Measurement in E Module (±100 mA)
Quantity:
Current
Function/Port:
E: Current Measurement
Use an accurate current source and connect to the cali-
brator’s terminals highlighted in the adjacent picture. In
case the accuracy of the current source is not good
enough, check the correct current using an accurate
Digital Multimeter.
Adjustment point ranges, mA
1:
20 … 50
2:
80 … 100
Generate a current that is inside the limits of the first
adjustment point range. Enter the correct current seen
on the Digital Multimeter’s display to
Span Reference

field in the calibrator. Continue through all the ad-
justment points
When all adjustment points are checked, select either
another

Function/Port
combination or save
the adjustment result as described in chapter

Adjusting the Frequency Measurement in E Module (±0.0027 … 50000 Hz)
Quantity:
Frequency
Function/Port:
E: Frequency Meas.
Use an accurate frequency source and connect to the
calibrator’s terminals highlighted in the adjacent picture.
In case the accuracy of the frequency source is not good
enough, check the correct frequency using an accurate
Digital Multimeter.
Adjustment point range, Hz
