0 to 5 R/h or 0 to 50 mSv/h
Accuracy
  Within 10% of reading between 10% and 100% of full-scale indication on any range, exclusive of energy response. Calibration source is 137Cs
Detector
  Chamber: 230 cc volume pressurized air ionization chamber to 8 atmospheres or 125 psi
Controls
  ON/OFF and MODE
Automatic features
  Auto-zeroing, auto-ranging, and auto-backlight
Response time
  Analog response time from 10% to 90% of reading for a full scale step increase is dependent on operating range. Response time for a step increase in radiation exposure rate from background:
Step to increase, background to & Time to reach 90% of final value: 400 µR/h & 4.8 sec
  4 mR/h & 3.3 sec
  10 mR/h & 4.3 sec
  40 mR/h & 4.5 sec
  100 mR/h & 2.7 sec
  1 R/h & 2 sec
  4 R/h & 2.7 sec
  The following shows time measured from 10% to 90% of final value for a step increase or decrease in exposure rate such that a range change does not occur. These values are the response times for the various ranges:
Range & 10% to 90%: 0 to 500 µR/h (5 µSv/h) & 5 sec
  0 to 5 mR/h (50 µSv/h) & 2 sec
  0 to 50 mR/h (500 µSv/h) & 1.8 sec
  0 to 500 mR/h (5 mSv/h) & 1.8 sec
  0 to 5 R/h (50 mSv/h) & 1.8 sec
Power requirements
  Two 9 V alkaline, 200 hours operation
Warm-up time
  Less than two minutes for initial operation when the instrument is in equilibrium with ambient temperature
Display LCD analog/digital with backlight
Analog 100 element bar graph 2.5 inch (6.4 cm) long. Bar graph is divided into five major segments, each labeled with the appropriate value for the range of the instrument
Digital 2.5 digit display is followed by a significant zero digit depending on the operating range of the instrument. The units of measurement are indicated on the display at all times. Digits are 0.25 inches (6.4 mm) high. Low battery and freeze indicators are also provided on the display
Modes
Integrate mode Operates continuously 30 seconds after the instrument has been turned on. Integration is performed even if the instrument is displaying in mR/h or R/h
Freeze mode Will place a tick mark on the bar graph display to hold on the peak displayed value. The unit will continue to read and display current radiation values
