Recalibration
Recalibration with calibration
plate
An optional, 10 mm-thick (0.39 in) calibration plate is available for the purpose of checking a density
measurement quickly and easily (
28).
The calibration plate is located underneath the shutter (
10).
CAUTION
!
The shutter must be set to the ON position before a recalibration is carried out (
After commissioning a density measurement, the calibration plate is introduced into the radiation path
under constant conditions, as described below, and the displayed density value at the FMG60 is
determined and recorded.
Constant conditions comprise:
• Empty pipe (note local dose rate)
• Filled with a defined medium, e.g. water

Release the clamps
A0018517
Slide the calibration plate into the
radiation path to the upper limit
stop.

Tighten the clamps again.
Perform the recalibration.
