2: Pulled out the Probe, as shown below, Hold the main body in the left hand, pinch the aviation plug "plug the card buckle tightly with thumb and index finger of right hand, pull towards the direction of the probe, the probe will be pulled out.
1. Probe connect method is push pull (snap). Non rotating the instrument probe.
2. Detector receiving window facing the UV light source, Can get current test point of UV radiation power density, and at the same time, shows a maximum (Pmax), the current value （PRT) , energy (E) or measurement time (T).
3. There is a magnet on instrument probe’s back , can be adsorbed on the iron plate, convenient for fixation.
4. Please press “POWER”button for power off, while not in use.
5. Avoid contact with corrosive substances, away from high temperature and high humidity environment.
6. Please Power Off and put it in the special packing, safekeeping.
7. Calibrate Period: The proposed calibration period is one year.
8. The ultraviolet probe is very sensitive to humidity change , so the preservative environment is very important. Please be sure to put the probe preserved in low humidity environment while the instrument not in use for a long time, For example, keep the probe in dry plastic bag.
