Alpha and beta pulses have different audio tones, so that the user can
discriminate between the two. A two-position momentary action switch
allows either a meter reset, or displays the detector HV onto the meter. The
following six alarms may be set via the RS-232 port:
Alpha Ratemeter (0-999999 cpm)
Beta Ratemeter (0-999999 cpm)
Alpha + Beta Ratemeter (0-999999 cpm)
Alpha Scaler (0-999999)
Beta Scaler (0-999999)
Alpha + Beta Scaler (0-999999)
These alarm points, when exceeded, light the meter face LED, marked
ALARM
, and activate the audio speaker. The ratemeter alarms are non-
latching (will cease when the radiation level drops below the alarm point).
The scaler alarm will continue until the
RESET
is pressed, or the next scaler
count is started.
The digital display is a full 6-digit liquid crystal display (LCD) display, which
is direct-driven for good viewing and a wide temperature response from -4
to 60 °C (40 to 140
o
F). The digital display displays the scaler count, and
prior to each sample logging, displays the current sample number. The
display also has an arrow symbol for counting overflow and two colons that
indicate that a scaler count is in progress.
The Model 2360 communicates through an RS-232 port located on the
instrument can. The computer interface software is supplied on CD and
includes the following functions:
downloading of header and logged data into an ASCII file
setting and reading of instrument parameters/header
information
setting of the
