What safety precautions should be followed when using the SISCO UT385?
Never stare into the laser beam directly or expose eyes to reflected laser light to avoid eyesight impairment or blindness. Be especially careful with high frequency lasers, which are invisible.
Do not input a laser over 40mW as the sensor may be damaged.
Keep the sensor illuminated surface clean and free from scratches and contamination to avoid inaccurate measurements.
Check the device and accessories for any damage or abnormality before usage. Do not operate if the product is damaged or suspected to be faulty.
Do not open the meter shell or change the internal circuit.
Change the battery in time when the low battery icon blinks on the LCD. Remove batteries during long term storage to avoid leakage.
Do not use or store the meter in environments with high temperature, high humidity, flammable, explosive, or intense electromagnetic conditions.
Clean the meter shell with a soft damp cloth and neutral detergent. Do not use abrasive or solvents.
