Safety & Warnings
The safety warnings and precautions explicitly present in the manual include:
– Read the operation manual completely before using the device and follow all safety instructions.
– The device is for indoor use, at altitudes up to 2,000 meters.
– Avoid working alone.
– Use the device only as specified in the manual; otherwise, the protection provided by the meter may be impaired.
– Never measure voltage when the current measurement is selected.
– Do not use the device if it looks damaged.
– Inspect the leads for damaged insulation or exposed metal and replace damaged leads.
– Disconnect the power and discharge all high-voltage capacitors before testing in the resistance, continuity, and diode function.
– Be cautious when working above 70VDC or 33VRMS and 46.7V peak, as such voltages may cause a shock hazard.
– Always keep hands behind the protective guard of the probe while measuring.
– Select the proper function and disconnect the test leads from test points before changing functions.
– Always use the specified battery.
– The meter is safety-certified in compliance with EN61010 (IEC 1010-1, IEC 1010-2-031) installation Category IV 600V/ III 1000V Pollution Degree 2. To maintain its insulation properties, use standard or compatible test probes.
– Under the influence of an RF field according to the standard, the supplied test leads will pick up induced noise. For better shielding, a short-twisted lead should be used.
