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).Avoid vibrations of the instrument to prevent affecting the detection
accuracy.
(3).Due to the randomness of radon alpha decay, when measuring
low-concentration radon, the count value may exhibit an uneven
distribution phenomenon, or there may be slight differences in
measurement results between different devices. This is a normal
phenomenon and not an inaccuracy of the instrument.
(4). After measuring high-concentration radon, residual radon and radon
daughters will be adsorbed inside the equipment. Complete decay may
take between 24 hours and 3.8 days, depending on the radon pollution
level. Therefore, after measuring high-concentration radon, it is
recommended to wait 24-48 hours before obtaining effective measurement
data every time the measurement location is changed.
9.Q&A
Q1: The screen doesn't show data and the value shows "--". What does it
mean?
A: The minimum test time for the first data appearance is 6 hours. Please
wait.
