 GEOelectronics built. Otherwise known as a Pulser or CPM(Counts Per Minute) Calibrator. CDV-700 and similar simple Geiger Counters have only one Calibration Potentiometer. This instrument therefore has only one CPM rate. This rate is 15,000 CPM by default. By replacing internal jumpers, any ONE of 9 CPMs can be selected for use. Wall-type power supply and 9V battery clip, plus programming jumpers included. Simply connect to your CDV-700 via the BNC connector (If you have not converted your CDV-700 to BNC, shame, we have a kit for that, even one that includes the tooling), clip on the battery and turn the calibration knob so the meter reads the correct CPM. See instructions. This type of instrument is a temporary substitute for the probe on a Geiger Counter, giving the correct polarity and waveshape in a known CPM to calibrate the Geiger Counter by way of it's calibration potentiometers. Some Geiger Counters like the CDV-700 have only one calibration potentiometer, we offer this economical version for those. See Ludlum Measurements Support page for manual on the Ludlum Model 500 to learn how to use a pulser. See our other ads for more instrumentation pertaining to Radiation Detector Calibration. Designed by Bill Beamon (KD4FNC)and built/tested by GEOelectronics (K0FF)
