3.3 Operation
Once the detector/preamplifier/readout devices have been installed and the high voltage has been
adjusted, operation of the Model 943-27 Current Mode Beta Scintillation Detector is automatic.
Operation of the 943-27 Detector is controlled by the Model 943-227-17 Digital Preamplifier and the
Model 942A-200C Digital Ratemeter or Model 960 Digital Process Radiation monitoring system. Once
the power to the controlling device is turned on, detector operation begins. No operator interaction is
required.
An operational check source is normally provided with the sampling geometry. The check source is
actuated from the controlling device and is used to verify operation of the detector by producing an
upscale reading on the controlling device.
Normal Operation
If the measured radiation field is within the range of the detector during power-up, the uCi/cc value will be
displayed on the controller. The digital display will update once per second.
Alarms
The radiation alarms are initiated by the applicable controller. Refer to the applicable controller manual.
