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 remember
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
