1. SAFETY INFORMATION
WARNING
To ensure safe operation, and in order to exploit to the full
functionality of the meter, please follow the directions in this
section carefully.
This multimeter has been designed according to IEC-1010 concerning
electronic measuring instruments with an overvoltage category（CAT ）and
pollution 2.
Follow all safety and operating instructions to ensure that the meter is used
safely and is kept in good operating condition.
1.1 PRELIMINARY
1.1.1 When using the meter, the user must observe all normal safety rules
concerning:
Protection against the dangers of electrical current
- 1 -
Protection of the meter against misuse
1.1.2 When the meter is delivered, check if it has been damaged in transit.
1.1.3 When poor condition under harsh preservation or shipping conditions
caused, inspect and confirm this meter without delay.
1.1.4 Test leads must be in good condition. Before using verify that the
insulation on test leads is not damaged and/or the leads wire is not
exposed.
1.1.5 Full compliance with safety standards can be guaranteed only if used
with test leads supplied. If necessary, they must be replaced with the
same model or same electric ratings.
1.2 DURING USE
1.2.1 Never exceed the protection limit values indicated in specifications for
each range of measurement.
1.2.2 When the meter is linked to a measurement circuit, do not touch
- 2 -
unused terminals.
1.2.3 Do not measure voltage if the voltage on the terminals exceeds 600V
above earth ground.
1.2.4 Always be careful when working with voltages above 60V DC or 30V
AC rms, keep fingers behind the probe barriers while measuring.
1.2.5 Never connect the meter leads across a voltage source while the
function switch is in the current, resistance, diode or continuity mode.
Doing so can damage the meter.
1.2.6 Before stir the transform switch to change functions, disconnect test
leads from the circuit under test.
1.2.7 When carrying out measurements on TV or switching power circuits
always remember that there may be high amplitude voltages pulses
at test points, which can damage the meter.
1.2.8 Never perform resistance measurements on live circuits.
- 3 -
1.2.9 If any faults or abnormalities are observed, the meter can not be used
any more and it has to be checked out.
1.2.10 Never use the meter unless the rear case is in place and fastened
fully.
1.2.11 Please do not store or use meter in areas exposed to direct sunlight,
high temperature, humidity or condensation.
1.3 SYMBOLS
Important safety information, refer to the operating manual.
Dangerous voltage may be presence.
Double insulation（Protection class ）.
Earth ground
1.4 MAINTENANCE
1.4.1 Please do not attempt to adjust or repair the meter by removing the
- 4 -
rear case while voltage is being applied. A technician who fully
understands danger involved should only carry out such actions.
1.4.2 Before opening the case of the meter, always disconnect test leads
from all sources of electric current.
1.4.3 Do not use abrasives or solvents on the meter, use a damp cloth and
mild detergent only.
1.4.4 ALWAYS set the power switch to the OFF position when the meter is
not in use.
1.4.5 If the meter is to be stored for a long period of time, the batteries
should be removed to prevent damage to the unit.
