Model 2360

General Purpose Data Logger

Part Number: 48-2872

Features

Scaler / Ratemeter / Data Logger
Simultaneous Alpha & Beta Measurements with Audio Discrimination
Logs 550 Data Points
Analog & Digital Display
Six Separate Alarms
Overload Protection
RS-232 Port

If you need to separately count alpha and beta concurrently and log the results, the Model 2360 will be the right tool. This instrument is an optimized Alpha-Beta Ratemeter, Scaler, and Data Logger that offers a traditional analog readout supplemented with a digital LCD for the scaler function. This meter supports many different externally connected detectors; two of the more popular ones are noted below.

Up to 550 data points can be stored. Each data point consists of a sample number, date/time stamp, both alpha and beta sample measurements, and a 10 character location identifier. The location identifier can be input via an optional external device through the RS-232 serial port.

A front panel mounted three-way switch facilitates selecting alpha only, beta only, or alpha plus beta. Other controls include a rotary switch for selecting any of the four-decade ranges, battery test, and instrument shut-off; a switch for viewing the high voltage or resetting the counts; an audio volume adjustment knob; a scaler count time selector rotary switch; and a handle mounted push-button for logging and starting scaler count cycles.

Specifications

Meter Dial	0 - 500 cpm, 0 - 2 kV, BAT OK, OL (overload); (others available)
Scaler	6-digit LCD display with 0.64 cm (0.25 in.) digits, overflow arrow, colons to indicate when a count is in process, and backlight
Data Logger	Capable of storing up to 550 individual data points with the following identifiers for each point (all data is stored in non-volatile memory allowing batteries to be removed without loss of data): Alpha and beta sample counts Sample number Date/Time stamp Scaler count time 10 character location identifier (can be set by ASCII terminal or PC)
Header Information	6 lines of user defined memory at the beginning of the stack for storing user name, survey name, serial numbers, etc. (information is dumped with logged data)
Overload	Senses detector saturation, indicated by red lamp on meter and meter deflecting to full scale (internally adjustable)
Count Time Range	0.1 to 60 min. with capability to preset user-programmed value
Alarm	Has alarm capabilities on both the scaler and ratemeter. Both circuits allow for independent alarm settings of the alpha channel, beta channel, and the alpha/beta channel. The scaler alarm setpoints can be set at any point from 0 to 999999 counts, and the ratemeter alarms can be set at any point from 0 to 999999 cpm. Alarm points can be set via the keypad or PC
Controls	Reset / Read HV: A two-position, momentary action switch to allow for the meter to be reset or a reading of the HV setting Count Type: Toggle switch to select alpha+beta, alpha only, or beta only Audio Volume: Rotary knob volume control, greater than 60 dB at 61 cm (2 ft), full volume, selectable dual or individual click-per-event for alpha and beta counts and divisions of 1, 10, 100, or 1000 events per click (beta counts only) Instrument: 6-position rotary knob for instrument off, battery check, and range multipliers: x1, x10, x100, x1000 Count Time: Switch selectable times of 0.1, 0.5, 1, 2, 5, 10, or 60 min. Also allows for a specific count time to be set from a PC. Logging Pushbutton: Located in handle, activates scaler and/or log a count
Logging Function Control	Internal selection that enables the pushbutton to log a ratemeter reading, initiate a scaler count and log the resulting reading, log both the scaler and ratemeter reading, or disable the logging function
Response Time	7 seconds on x1 range, 2 seconds on all others
High Voltage	Adjustable from 200 to 2000 Vdc (can be read on meter)
Threshold	Alpha: -40 to -700 mVdc Beta: -2 to -15 mVdc
Calibration Due Date	An internal date that disables the instrument if the required calibration interval has been missed
Temperature Range	-20 to 50 °C (-4 to 122 °F) May be certified for operation from -40 to 65 °C (-40 to 150 °F)
Battery Life	Typically 250 hours with alkaline batteries (battery condition can be checked on meter)
Data Output	9-pin RS-232 port for connection to PC for data download and adjustment of setup parameters. A one meter RS-232 to USB adapter cable is included. PC interface software is available for download here.
