III. Safety instructions
Safety standards
This instrument strictly follows the EN 61010-1: 2010, EN 61326: 2013, RoHS, pollution grade II safety
standard, CAT II 600V.
Unplug the power cord when the instrument is not in use.
Note: In the case that the instrument is not used in accordance with the operation instructions,
the protection provided by the instrument may be weakened or lost.
CLEANING
Be sure meter is turned off and wipe with a clean ,dry lint-free cloth.
Do not use abrasive cleaners or solvents
Power cord
specification:
1) Before using the instrument, please check if there is any item which is damaged or behaving abnormally.
If any abnormal item is found (such as: test lead bared, housing case damaged, LCD broken, etc.),
please stop using the instrument. It is strictly prohibited to use an instrument without shell cover.
Otherwise, there is a danger of electric shock.
2) If test lead is damaged, replace with the same type or of the same specifications.
3) Do not touch bare wire, connectors, input terminal or circuit being measured.
4) Use caution to measure voltage >DC 60V or AC 36Vrms, keep fingers behind finger guard to prevent
shock hazard.
Before each use, verify operation by testing a known working circuit that is within the rating of this unit.
5) When measuring unknown voltage, switch the dial to the maximum range position.
6) Do not impose voltage or current exceeding the specified ones on the instrument.
7) Functional dial should be switched to proper position. After each measure, disconnect the test leads
with the circuit. Pull out the power line if not use for long time. Do not switch the functional dial during
measurement.
