Model/Type
Serial №
If your electrometer’s manufacturer is other than IBA Dosimetry (or Scanditronics-Wellhöfer), please
consider that we are not authorized to perform any repair or internal adjustment of the device.
If you are sending more than one electrometer, please submit a separate request for each electrometer.

Calibration points
± 1 nA
± 100 pA
± 1 nA
± 10 pA
± 100 pA
± 1 nA
Select points from the range of
± 1 pA to ± 10 µA:
In case the electrometer has two or more measuring channels, calibrations according to the
request will be performed for each channel.
If a calibration point is available in two electrometer ranges, the calibration will be carried out in
the lower range.
3.3 Calibration with Linearity Check
The entire requested extent (with positive and/or negative current) of the electrometer will be
calibrated.
