10 Real time Calibrating
The DRM-3000 meter and detectors are supplied with calibration certificates as per the examples
below:
Calibration of the Internal Detector can be carried out by connecting the DRM-3000 to a PC
directly using the Ethernet to USB cable or remotely through the Ethernet using a dynamic IP
address.
The DRM is positioned in the calibration chamber as shown below and care should be taken to
ensure that both GM tubes are situated within the same homogeneous dose rate field.
The DRM-3000 is placed in a jig upside down to allow easy accessibility to the power and
communication cables.
The center of the beam should be focused on the corner between the face and top of the meter.
