Radiation Detected
Alpha, Beta, Gamma and X-Rays.
Detector
Geiger-Muller tube Ne + Halogen filled with a .38" effective diameter 1.5-2.0 mg/cm2 mica end win-
dow.
Detector Sensitivity
· Alpha above 3.0 MeV
· Beta above 50 KeV
· Gamma above 7 KeV
Countable Pulse Range
Converted Radiation Range
The Liquid Crystal Display (LCD) is 16 character by 2 line that provides an easy to read output, see image
to right. LCD has an on-off backlight switch . LCD display continuously updates counts per second (or
counts per minute) on line one while displaying converted radiation level second line.
Backlight Switch tur ns on and off the LCD backlight,.
The LED marked Pulse—is a secondary radioactive particle indicator it blinks each time a radioactive par-
ticle is detected by the Geiger Counter.
The Power Switch turns power on or off to the DTG-01.
The Speaker Switch turns the sound on or off to the internal speaker. The speaker is a secondary radioac-
tive particle indicator. It clicks each time a radioactive particle is detected. Note: Plugging a headphone in
the headphone jack will automatically turn off the internal speaker.
Headphone jack is a standar d 3.5mm for pr ivate listening. Using a headphone automatically tur ns
off the internal speaker of the Geiger counter.
External power jack is available for extended r eadings wher e batter y oper ation may not be pr acti-
cal. Power jack is 2.5mm x 5.5mm. Power input is 9VDC or 9VAC @ 200mA min. current. Mobile oper-
ation uses a 9V battery.
TTL Serial and Digital Pulse outputs for PC available via 3.5MM ster eo connector .
Random Number Generator function outputs a r ange of r andom number s for ever y r adioactive
particle detected.
Included 9V wall transformer power s the DTG-01 by connecting to the back of the unit by way of a
2.1/5.5mm jack and socket.
