Safety Advice
1.When the tester use Disposable alkaline batteries, do not charge it. Ensure the correct
polarity installation,when replace the battery.
2．When the products are not in use, please remove the batteries and kept separate to avoid
instrument damage caused by battery leakage. If leakage occurred, Please do not touch.
3. To prevent electric shock, do not open the product case, only the authorized qualified
professionals can do the maintenance; Do not expose the testers to rain or wet conditions, to
avoid the risk of fire or electric shock
4. Instruments used LCD screen. Do not fall the instrument. If the LCD are seriously hit, it may

5.5 Wavelength Automatic Identification
Connect The light source with its same serials power meter THE MATCHED OPTICAL POWER
METER.
Enable light source be Under “Wave ID” operation mode: press or of light source to laser on
its matched power meter, Hold down for few seconds，light source will be enter into Wave ID mode,
also “--AU” will be shown on the upper right of LCD for a indication.
Enable power meter be under “Wave ID”operation mode: Hold down for few seconds，power meter
will be enter into Wave ID mode, also “--AU”will be shown on the upper right of LCD for a indication.
Once the ID information is changed from light source(press to change wavelength), after 3 to 5
seconds later, the detected information on optical power meter also will be changed automatically
according to light source. Please refer to below figure(5-14) for easy understanding.
