Canberra ADM300 - Survey and Monitoring Modes; Gamma Survey

2.2.1.1 SURVEY AND MONITORING MODES
In the survey or monitoring modes the operator wears the survey meter using the
shoulder carrying strap. The ADM300 must be held in at a consistent angle to assure
accuracy and uniformity of readings. If the Gun Handle is used, the survey meter
can be held more comfortably.
2.2.1.2 GAMMA SURVEY
The beta window cover located on the rear panel of the ADM300 must be closed
when measuring gamma radiation. Detection is provided by both low-range and
high-range detectors located in the unit. The survey meter auto-ranges from low to
high and high to low range smoothly and without interruption.
