conjunctions with the supplied test leads. To replace damaged test leads with only
the same model or same electric specifications.
4-2 To avid risk of electric shock, do not use the meters before the cover is in place.
4-3 The range switch should be right position for the testing.
4-4 To avoid electric shock and damaging the instruments, the input signals are
forbidden to exceed the specified limits.
4-5 When measuring TV set or switched power, attention should be paid to the
possible pulses that may bring destruction to the circuit.
4-6 Range switch position is forbidden to be changed at random during
measurement.
4-7 Take caution against shock in the course of measuring voltage higher than DC
60V & AC 30V.
4-8 Protection fuse should be replaced only with same type and same specification.
4-9 After operation is finished, set function switch at OFF range to save battery
power.
4-10 If the meter is without usage for long time, take out battery to avoid damage
by battery leakage.
