Safety Information



Read the following safety information carefully before attempting to operate or service the

meter.

To avoid damage to the instrument do not exceed the maximum input limits shown in the

technical specifications.

Do not use the meter or test leads if they appear damaged.

Use extreme caution when working around bare conductors or bus bars. Accidental contact

with the conductor could result in electric shock.

Use the meter only as specified in this manual; otherwise, the protection provided by the

meter may be impaired.

Read the operating instructions before use and follow all safety information.

Use caution when working with voltages above 60VDC or 30VAC RMS. Such voltages

represent a shock hazard.

Before taking resistance measurements or testing continuity, disconnect the circuit under test

from the main power supply and remove all loads from the circuit.

Safety symbols

Caution! Refer to this manual before using the meter.

Dangerous voltages.

Meter is protected throughout by double insulation or

reinforced insulation.

When servicing, use only specified replacement parts.

Complies with EN-61010-1, IEC 1010-2-32
