(14) PDF report
Connect the device to the USB interface of the computer, and the prompt
box "Create PDF file, please wait" pops up on the screen. No more than
25s to create the report(the wait time depends on the amount of data).
After creating the PDF. Users can view the historical data in PDF format
in the disk through the computer side.
Each time the radon meter is turned on, a new PDF file is automatically
generated on the USB flash drive inside the device, which can store up to3
PDF files. If it is full, the new file overwrites the old one.
Note: After each measurement is completed, it is recommended to
copy and save the PDF file in time to prevent data from being
overwritten.
8.Precautions
(1)When the instrument indicates low battery power, please charge it in
time to ensure the normal monitoring of the measuring equipment.
(2) Due to the randomness of radon alpha decay, the count values may be
unevenly distributed when measuring low concentrations of radon, or there
are slight differences in the measurement results between different devices.
This is normal and does not mean that the instrument is inaccurate.
(3) Avoid intensive vibrations of the instrument to prevent affecting the
detection accuracy.
(4) After measuring high-concentration radon gas, residual radon and
radon daughters will be adsorbed inside the equipment. Depending on the
degree of radon pollution, it takes 24hours to 3.8days(maximum) to decay.
Therefore, after measuring high-concentration radon gas, please wait
24-48 hours later to restart.
(5)When the battery is charging, the internal temperature of the equipment
will increase. Therefore, the measured temperature data is the device
inside, not the ambient temperature.
