Introduction
he Ludlum Model 2360 Scaler/Ratemeter Data Logger is an easy-
to-use survey instrument incorporating the best of the analog and
digital worlds. Able to measure both alpha and beta radiation levels
simultaneously, the Model 2360 presents the data in scaler (digital
display) mode or ratemeter (analog meter) mode. The Model 2360 also logs
up to 550 data points, consisting of sample number, date/time stamp,
sample measurements (both alpha and beta, cpm if ratemeter measurement,
or counts per count time if logging scaler count), scaler count time, “S” or
“R,” identifying whether scaler count or ratemeter was logged, and location
identifier (10 characters).
Each alpha-beta data point is logged by simply pressing the button located in
the instrument handle. The appropriate scaler or ratemeter measurement is
taken, and both alpha and beta readings are logged into non-volatile
memory. An internal dipswitch allows for logging of the scaler reading,
ratemeter reading, both scaler and ratemeter readings, and NO logging. The
location identifier can be input by a PC or other RS-232 device prior to
logging a sample.
There are also 6 lines (15 characters each) of header information that can be
stored at the beginning of the non-volatile memory. The header lines can
contain such information as the user name, survey name, serial numbers, etc.
The “
CALIBRATION DUE DATE
” can also be stored in non-volatile memory,
which will disable the instrument when the internal clock date reaches the
stored date.
The Model 2360 has a long arc length (6.0 cm {2.4 in.}) meter face that
normally reads from 0 to 500 cpm. The main rotary switch allows for
multiplication ranges of ×1, ×10, ×100, and ×1000. The Model 2360 has a
three-position toggle switch on the front panel to switch between displaying
alpha, beta, or alpha + beta levels.
