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
ⅡⅡⅡⅡ
1000V, CAT
Ⅲ
Ⅲ
Ⅲ
Ⅲ
600V and pollution 2.
With proper use and care, the digital multimeter will give you years of satisfactory service.
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 danger of electrical attack
•
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 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 the same class.
1.2 DURING USE
1.2.1 Before using, you must select the right input jack, function and range.
1.2.2 Never exceed the protection limit values indicated in specifications for each range of measurement.
1.2.3 When the meter is linked to a measurement circuit, do not touch unused terminals.
1.2.4 Do not measure voltage if the voltage on the terminals exceeds 600V above earth ground.
1.2.5 At the manual range, when the value scale to be measured is unknown beforehand, set the range selector at
the highest position.
1.2.6 Always be careful when working with voltages above 60V DC or 30V AC rms, keep fingers behind the probe
barriers while measuring.
1.2.7 Never connect the meter with any voltage source while the function switch is in the current, resistance,
capacitance, diode, continuity
，
temperature, humidity, sound level or illuminance range, otherwise it will
damage the meter.
1.2.8 Before stir the transform switch to change functions, disconnect test leads from the circuit under test.
1.2.9 When carrying out measurements on TV or switching power circuits always remembers that there may be high
amplitude voltages pulses at test points, which can damage the meter.
1.2.10 Never measure any of resistance
，
capacitance, diode or continuity measurements on live circuits.
1.2.11 Never perform capacitance measurements unless the capacitor to be measured has been discharged fully.
1.2.12 Never use the meter under the condition of the explosive air, steam or dirt.
1.2.13 If any faults or abnormalities are observed, the meter cannot be used anymore and it has to be checked out.
