Safety Information
This Meter complies with the standards IEC61010: in pollution degree 2, category CAT III 1000V,
CAT IV 600V over voltage and double insulation.
Warning
To avoid possible electric shock or personal injury, and to avoid possible damage to the Meter or
to the equipment under test, adhere to the following rules:.
• Before using the Meter inspect the case. Do not use the Meter if it is damaged or the case (or
part of the case) is removed. Look for cracks or missing plastics. Pay attention to the insulation
around the connectors.
• Inspect the test leads for damages insulation or exposed metal. Check the test leads for
continuity.
• Do not apply more than the rated voltage, as marked on the Meter, between the terminals or
between any terminal and the grounding.
• The rotary switch should be placed in the right position and no any changeover of range shall be
made during measurement is conducted to prevent damage of the Meter.
• When the Meter working at an effective voltage over 60V in DC or 42V rms in AC, special care
should be taken for there is danger of electric shock.
• Do not use or store the Meter in an environment of high temperature; humidity, explosive,
inflammable and strong magnetic fields. The performance of the Meter may deteriorate after
dampened.
• When using the test leads, keep your fingers behind the finger guards.
• Disconnect circuit power and discharge all high-voltage capacitors before testing resistance,
continuity, diodes and current.
• Before measuring current, check the Meter fuses and turn off power to circuit before connecting
the Meter to the circuit.
• Replace the battery as soon as the battery indicator appears. Whit to low battery, the Meter
might produce false readings that can lead to electric shock and personal injury.
