 Pocket radiometer FD-3007K 
 Uses: 
 FD-3007K compact radiometer is based on the International Committee of radioactive Basic Radiation Protection (ICRP) recommendations (1997) and China Basic Radiation Protection Standard (GB-4792-84) requirements and develop a new generation of multi-radiometer. Set dose rate and dose measurements in one, an additional alarm and security alarm division of radioactive sites, providing cumulative dose, for monitoring the χ rays and γ-rays, radioactive isotopes are widely used in personnel protection testing, nondestructive testing, accelerators, nuclear medicine , γ radiation, the surrounding environment of nuclear facilities in the laboratory staff in personal safety monitoring.

 Pocket radiometer FD-3007K brief instructions 
 Interface from the display, alarm buzzer and OK (⊙), FUN (▲) two key components. 
 LCD display provides visual feedback, including: battery information, alarm conditions and radiation dose measured values ??and so on. 
 LCD liquid crystal display (display symbol description) 
 Dose accumulation? 15? High precision 
 Rate-dose-rate 30? Low accuracy 
 Setup settings? Battery Battery 
 Symbol Description 
 Battery symbol flashes when the battery voltage is low, you can also work a few hours or days 
 RATE symbolic value of dose rate display, flashing every 3-5 seconds after the effective update 
 Symbols show values ??accumulated dose DOSE 
 Setup parameters when lit symbol status 
 Dose measurements four significant digits, units of measurement displayed μSv / h, the cumulative display unit μSv. 
 Pocket radiometer FD-3007K on and off 
 Power: Press "OK" button for 3 seconds, turn, buzzer for a self-test. First display the current software version P1.00. Then automatically enter the dose rate measurement instrument state. 
 Off: Press "OK" button for 5 seconds, the display turned off, the instrument off. 
 Other operations OK (⊙), FUN (▲) 
 1??? Click "OK" button to switch between the cumulative dose and dose rate. 
 2.??? "FUN" to switch to the settings menu, set alarm thresholds, clear cumulative dose, mode settings.
