PCE-RAM 8
1.Product Introduction
• This product is a built-in high sensitivity reform counter as a detector of radiation dose monitoring instrument,
mainly used to monitor all kinds of radioactive workplaces of X, Beta, Gamma ray radiation, with high sensitivity,
fast response, accurate measurement, wide range and so on.
• Widely used in nuclear power plant, iron and steel chemical industry, radiation processing enterprises, radiation
therapy, reflex laboratory, home decoration radiation and other fields of staff for personal safety protection
monitoring.

1.Long press the Switch Button for about 3 seconds to start the instrument; Long press the on button again for
about 3 seconds to shut down the instrument.
2.When the instrument is on, the LCD backlight will automatically reduce the brightness after no operation for one
minute.
3.Press any button again to turn on the LCD backlight again without automatic shutdown function.
6-2.Instrument Switching Unit
1.Press the Unit Button to switch between µSv/h and µR/h, not only the current measured value, but also the
cumulative value and the maximum value (Save the current last display unit each time you shut down).
