  • Page 4: Safety Information

    SAFETY INFORMATION This meter has been designed according to IEC-61010 concerning electronic measuring instruments with a mea- surement category (CAT III 600 V) and pollution degree 2. Warning To avoid possible electric shock or personal injury, follow these guidelines: Do not use the meter if it is damaged. Before you use the meter, inspect the case.
  • Page 5 connecting the meter in the circuit. Remember to place the meter in series with the circuit. When servicing the meter, use only specified replacement parts. Use caution when working above 30Vac rms, 42V peak, or 60Vdc. Such voltages pose a shock hazard. When using the probes, keep your fingers behind the finger guards on the probes.
