2) The meter conforms to, double insulation, CA T II 1000V/CAT Ill 600V overvoltage standard, and pollution
degree 2.
2. Safety Information
1) If use the meter without following up the operating instructions, the protection provided by the meter may be
impaired or lost.
2) Do not use the meter if the rear cover is not completely covered up, or ii may pose a shock hazard and the
meter is designed for indoor use.
3) Check and make sure the insulation of the meter and test leads is in good condition without any damage
before use. If the insulation of the meter casing is found to be significantly damaged, or if the meter is
considered to be malfunctioning, please do not continue to use the meter.
4) Keep fingers behind the finger guards of the test leads when using the meter.
5) Do not apply more than 1 OOOV between any terminal and earth ground to prevent electric shock and damage
to the meter.
6) Use caution when working with voltages above AC 30Vrms or DC 60V. Such voltages pose a shock hazard.
7) The measured signal is not allowed to exceed the specified limit to prevent electric shock and damage to
the meter.
8) Place the function dial in the correct position before measurement.
9) Never turn the function dial during measurement to avoid damage to the meter.
1 O) Do not change the internal circuit of the meter to avoid damage to the meter or user.
11) Damaged fuses must be replaced with fast-acting ones of same specifications.
12) When· 11".D" is displayed, please replace the batteries in time to ensure measurement accuracy.
13) Do not use or store the meter in high temperature, high humidityfiammable, explosive, or strong magnetic
field environments.
14) Clean the meter casing with a damp cloth and mild detergent. Do not use abrasives or solvents.
15) Use of test probe.
TESTING IN CAT Ill/IV MEASUREMENT LOCATIONS
Ensure the test lead shield pressed firmly in place. Failure to use the CAT Ill/IV shield increase arc-fiash risk.
TESTING IN CAT II MEASUREMENT LOCATIONS
CAT Ill shields may be removed for CAT II locations. This will allow testing on recessed conductors such as
wall outlet. Take care not to lose the shields.
