Introduction
The ASM-990 series are easy-to-use instruments that detect
alpha, beta, gamma, neutron, or x-ray radiation within an operating range
of 1 ตR/hr to 1 R/hr or 1 to 5,000,000 CPM, depending on the probe
selection. Visual indication of measured values, as well as selectable
parameters, are displayed on the analog/digital display.
The units are compatible with Geiger-Mueller (GM)
detectors, neutron probes, proportional counters, and scintillation probes
operating from 500 to 1300 volts.
Applications
The ASM-990 series are designed to meet the high
technology requirements of health physics, medical physics, and
nondestructive testing applications. Radiation safety officers (RSO),
nuclear medicine laboratories, diagnostic xray and hospital emergency room
technicians, and environmental health physicists will appreciate this
intelligent survey meter with its cell phone-like multi-function key for
easy menu navigation.
The units, with purchased probe, are shipped calibrated
and ready-to-use. With the proper probe combination, this meter can be
used as a general survey meter, an area monitor, a wipe test counter, and
a contamination monitor.
The unit is supplied with a MHV connector to ensure
compatibility with all Victoreen probes. A Model 992 is available that
includes a fully calibrated internal energy compensated 1 R/hr GM
detector. The Model 993 features a fully calibrated internal pancake
detector as well as an internal energy compensated 1 R/hr GM detector.
Features
Survey Mode feature allows user to store up to 5
separate survey sequences
Infrared Data (IrDA) port
LCD readout
160 x 160 graphical LCD display shows digitized average
of the bar graph value
Analog scale has fifty-one elements arranged in a
linear bargraph. Each element represents 2% of full scale. Scale markings
are 0, 2, 4, 6, 8 and 10. Scale length is 2.2 inches (5.6 cm)
Scale multiplier is 0.0001 to 1 million, depending on
the probe selected and the units activated
LCD also displays selected measurement units, status
icons, and real time clock
Pushbutton controls

background light for a preset or indefinite amount of time
Start/Stop/Rst/Save saves current
data; starts and stops recording of data; resets internal counter in
scaler mode
Sel activates the menu
systems; allows user to choose particular settings, etc.
Up/Dn arrows enables user to
navigate between various menus/selections
