Instructions
1,power button ON to boot, Boot automatically display real-time monitoring interface
2, After the shutdown, press and hold off zero current consumption
3, Triangular start button is used to measure the mean, Natural environment there is background radiation (background radiation) It will fluctuate within a certain range.
4, The top of the screen displays a blue font for the inchsecondinch real-time update of the dose rate, which is characterized by large fluctuations, update speed, real-time, is the mean of the middle of the red font display, is a mean dose rate period, when detecting an item or the environment when press the start button (this time can no longer move the tester)
Enter the state average measurement will display the measurement results after the end of the trend diagram below presents the average real measurement value of each moment, mean measurement is characterized by high precision, the effective dose equivalent response rate real environment, but the elapsed time is longer,
6, horn button is used to select the sound source device, each time you press the switch once source.
When the small speaker icon is displayed when the artificial alarm sound (only achieve this status only sound the alarm threshold)
When the mute icon is displayed when that turn off all sources.
7, The scale key (right key) is used to switch the alarm threshold,
Four optional 0.5 / 1.0 /2.0 /5.0
When the source is selected as the speaker state when the threshold is set to be valid
