Quick Start Guide

The Introduction video will help you familiarize yourself with the Radiation Alert® Inspector USB handheld digital radiation detector. This video covers the operation of the newest Inspector EXP and Xtreme models as well. The function, settings, and menu operation of the latest Inspector models is identical. However, the Inspector EXP has a detector in the probe handle at the end of a one meter cable instead of in the main body of the meter, like the SEI Inspector USB and Inspector Xtreme USB.

The Inspector uses a Geiger-Mueller tube to detect radiation. The Geiger tube generates a pulse of electrical current each time radiation passes through the halogen quenched tube and causes ionization. Each pulse is electronically detected and registers as a count. The Inspector displays the counts in the mode you choose.

PRECAUTIONS:

  • CAUTION: Never touch the Inspector to a surface that may be contaminated. You may contaminate the instrument.
  • Do not leave the Inspector in temperatures over 100° F (38° C) or in direct sunlight for extended periods of time.
  • Do not get the Inspector wet. Water can damage the circuitry and the mica surface of the Geiger tube.
  • Do not put the Inspector in a microwave oven. It cannot measure microwaves, and you may damage it or the oven.
  • This instrument may be sensitive to and may not operate properly in radio frequency, microwave, electrostatic, and electromagnetic fields.
  • If you do not expect to use the Inspector for longer than one month, remove the battery to avoid damage from battery corrosion. Change the battery promptly when the battery indicator appears on the display.
  • CAUTION: When using the unit at altitudes higher than 8000 feet (2438.4 meters), it is possible that the tube window can rupture.
