SAFETY INSTRUCTIONS

High voltage
WARNING! To avoid the electric shock and physical injury, and to avoid possible damage to the meter
and the tested equipments, read this operation manual carefully before using this meter, and follow the following
safety guidelines:
Before use, check and make sure that the instrument's plastic chassis, the test leads and the insulation layer

are intact.
User the meter only as specified in this manual. Otherwise, the protection provided by the meter may be

expired.
Never measure voltage while the test leads are inserted into the current input terminals.

Do not use the meter if it looks damaged

Inspect the leads for damaged insulation or exposed metal, check test lead continuity. Replace damaged

leads.
Disconnect the power and discharge all high-voltage capacitors before testing in resistance, continuity and

diode function.
Be cautious when working at voltage above DC60V or AC42V. Such voltages may cause a shock hazard.

When undertaking measurement, keep your fingers behind the guard's plant on the test leads or probes.

Select the proper function and range for measurement to avoid damage to the meter.

Disconnect the test leads from the test points before changing to another function.

The specifications are subject to change without notice.
The content of this manual is regarded as correct. If any error or omits is found, please contact with the
