1.1.2 When the meter is delivered, check whether it has
been damaged in transit.
1.1.3 After being stored and delivered under harsh
conditions, the meter should be checked and
confirmed whether any damages have been incurred.
1.1.4 Test leads must be kept in good condition. Check
whether the insulation on test leads has been
damaged and any wire has been exposed.
1.1.5 Use the test leads supplied to ensure operation safety.
If required, they must be replaced with test leads of the
same model or class.
1.2 DOS AND DON'TS
1.2.1 Use the right input jack, function and range.
1.2.2 Do not take measurements that exceed the protection
limit values indicated in the specifications
1.2.3 Do not touch the metal tips of the test leads when the
meter is connected to the circuit to be measured.
1.2.4 Keep your fingers behind the probe barriers when
taking a measurement with an effective voltage above
60V DC or 30V rms AC.
1.2.5 Do not take voltage measurement if the value between
the terminals and earth ground exceeds 1000V.
1.2.6 Select the highest range if the value scale to be
measured in the manual range is unknown.

1.2.7 Do not connect the meter to any voltage source while
the rotary selector is in the current, resistance,
capacitance, diode, continuity range.
1.2.8 Disconnect the test leads from the circuit under test
before turning the rotary selector to change functions.
1.2.9 Be careful that high voltage pulses at test points may
damage the meter when measurements are being
taken on the circuit of TV switch power.
1.2.10 Do not measure the resistance
continuity of live circuits.
1.2.11 Do not take capacitance measurements until the
capacitor to be measured has been fully discharged.
1.2.12 Do not use the meter near explosive gases, steam or
dirt.
1.2.13 Stop using the meter if any abnormalities or faults are
observed.
1.2.14 Do not use the meter unless its rear case is securely
fastened in its original position.
1.2.15 Do not store or use the meter in areas exposed to
direct sunlight, at high temperature or with high relative
humidity.
