General Purpose Ratemeter/Scaler - Model 2241-3
CE Seal
Introduction

This instrument is a general purpose, digital ratemeter with a built-in scaler that provides timed counts over a user specified period. This system will store detector setup information for up to four detectors and offers a front-panel mounted rotary switch so personnel can quickly swap detectors in the field.

The LCD presents readings in a four-digit, moving decimal format together with one of a wide range of available units of measure and is accompanied by several operational and alert icons. The LCD backlight can be activated and remains lit for a user-adjustable interval.

This instrument features adjustable alert and alarm setpoints for both the Ratemeter & Scaler modes. Front-panel controls include a rotary switch for selecting between Off, and up to four detector setups, separate switches for selecting Ratemeter Mode and Scaler Mode, audio on/off and fast/slow response time, plus pushbuttons for activating the LCD backlight, and for either resetting the counts or acknowledging any alarms. 

Calibration, user configured alarms, scaler count intervals and detector setups can be configured via an internally housed switchboard or through an RS-232 serial interface to a PC.
