Safety & Warnings
An electrical shock causing 10 milliamps of current to pass through the heart will stop most human heartbeats. Voltage as low as 35 volts dc or ac rms should be considered dangerous and hazardous since it can produce a fatal current under certain conditions. Higher voltages are even more dangerous. Observe the following safety precautions:
1. Do not exceed the specified input ratings for DC and AC volts, ohms, and current ranges to avoid personal injury or damage to the instrument.
2. Remove test leads from the instrument and point of measurement before replacing fuses or performing any servicing on the multimeter.
3. Use only shrouded safety type test leads like those supplied. Periodically inspect insulation for any burns, cuts, or breaks. Never use test leads with exposed bare wires or poor insulation.
4. Turn off equipment while making test connections in high-voltage circuits. Discharge high-voltage capacitors after removing power.
5. For voltage or current measurements in high voltage equipment, do not touch equipment, meter, or test leads while power is applied.
6. Familiarize yourself with the equipment being tested and the location of its high voltage points, but remember that high voltage may appear at unexpected points in defective equipment.
7. Use an insulated floor material or floor mat to stand on, and an insulated workbench surface; ensure such surfaces are not damp or wet.
