Safety & Warnings
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 to ensure the protection provided by the meter is not impaired. Never measure voltage when the current measurement is selected. Do not use the device if it appears damaged. Inspect leads for damaged insulation or exposed metal and replace damaged leads. Disconnect power and discharge all high-voltage capacitors before testing in resistance, continuity, and diode functions. 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 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 insulation properties, use standard or compatible test probes. Under the influence of RF fields, the supplied test leads may pick up induced noise; a short-twisted lead should be used for better shielding effect.
