Attention:
Be careful when rotating the switch to avoid damage to
the sensor.
Under normal conditions, the meter can detect the current radiation
value quickly and accurately when the sensor window of rays aim at
radiation source.
6-2. Power source and back light switch button.
Note:
The stored data will still be saved after turn it off, but the
stored data will be lost if it is turned off Inappropriate.
1. Press the switch button for 2 seconds, it will beep shortly, and ac
-
tivate the LCD display; Press again the switch button for 2 seconds
to shut down the LCD display.
2. After turn it on, and press the switch button, the LCD back light
will be activated, press again, the back light will be shut off. To save
energy, the back-light will be automatically shut off 1 minutes after
be activated.
6-3. Sv/h and Rem/h button for current radiation dose rate
1. Press the button and into standard mode, it displays the current
measurement value (µSv/h). The measurement results could be
read in data mode, and bar graph as well. The bar graph on the
lower corner of display will change as the reading fluctuating and is
distributed in scales as 0.1,1,10,100. Note: If the reading is too low,
the bar graph will be show in a line.
2. Sv/h and Rem/h unit conversion
Press the button for conversion, which is based on the formula:
10µSv/h = 1mRem/h

6.4. Sv Dose accumulation
The digital nuclear radiation scanner could also do the measure
-
ment, recording the accumulated radiation dose at specific time. The
initial unit is µSv, and it will automatically convert to mSv or Sv as the
measured dose rate getting higher.
6-5. Button for Dose Rate accumulation
1. Press “SV” button, and enter into the regular infinite dose rate
accumulation calculation mode with dose rate icon ( µSv ) on the
display. Press the button again, and enter into timing measurement
mode (default value is 60 minutes). Press the button once again to
stop the timing measurement mode with a beep warning, and it dis
-
plays the current accumulated measurement value; Press the button
one more time, it will return to regular infinite dose rate accumulation
calculation mode.
2.
Under the timing measurement mode, press this button
for 2 seconds for setting the measuring time, then it displays dose
icon (µSv) and time unit icon “min”. Now, the display will indicate 3
numbers as 060 as default value, which means 60 minutes, and the
maximum is 999 minutes.
The first digit(the hundreds) will be in flashing state for setting
directly.
press Enter button once to set tens digit ;
press Enter button the second time to set single digit;
press ESC button and return to the previous state;
press Enter button for the 3rd time to confirm the time setup
and shows the current setting value;
press Enter button for the 4th time into dose accumulative
working state, and the icon “TIME” on the top left corner starts flash
-
ing. press down button or up button to adjust the display
value.
