Adjustment of Measurement Ranges
Adjusting the Voltage Measurement in E Module (±50 V)
Quantity:
Voltage
Function/Port:
E: Voltage Measurement
Use an accurate voltage source and connect it to the
calibrator’s terminals highlighted in the adjacent picture.
In case the accuracy of the voltage source is not good
enough, check the correct voltage using an accurate
Digital Multimeter.
Adjustment point ranges, mV
1:
9 … 12
2:
19 … 25
3:
39 … 50
Generate a voltage that is inside the limits of the first
adjustment point range. Enter the correct voltage seen
on the Digital Multimeter’s display to

justment points
When all adjustment points are checked, select either
another

Function/Port:
E: Low Voltage Measurement
Use an accurate millivolt source and connect it to the
calibrator’s terminals highlighted in the adjacent picture.
In case the accuracy of the voltage source is not good
enough, check the correct voltage using an accurate
Digital Multimeter.
