LCD display, and if the push button switch is at the trigger position. Check if the
meter pen is contacted reliably, connected correctly, and grounded well and etc. In
order to avoid electric shock.
3. Only if the meter is used with the matched meter pen, can it meet the requirement
of safety standard. When the line of the meter pen is damaged, it is necessary to
replace another one of the same model or the same electrical specification.
4. Don’t use other unconfirmed or disapproved protector tube to replace the protector
tube inside the meter. Only the protector tube of the same model or same specifica-
tion can be replaced. Before the replacement, the meter pen must leave the measur-
ing point and ensure there is no any signal at the input terminal.
5. Don’t use other unconfirmed or disapproved battery to replace the battery inside the
meter. Only the battery of the same model or same electrical specification can be
replaced. Before the replacement, the meter pen must leave the measuring point and
ensure there is no any signal at the input terminal.
6. When the electrical measurement is made, never let your body get in touch with the
ground directly, and don’t touch uncovered metal terminal, output port, lead clamp
and etc. Where earth potential may exist. Dry clothes, rubber shoes, rubber cushion
and other insulating material are usually used to keep your body insulated against
the ground.
7. Don’t store and use it in the high-temperature, high-humidity, inflammable and strong
magnetic field environment.
8. It may do damage to the meter and endanger the operator’s safety if the voltage
value beyond the permitted ultimate voltage value is measured. The ultimate voltage
value permitted for measurement is marked on the instrument panel, and never
measure the value exceeding the standard. Don’t input the ultimate value out of
regulation in order to avoid electric shock and the damage to the meter.
9. When the meter pen is inserted into the current socket, don’t measure any voltage for
fear that the meter should be damaged and the operator’s safety be endangered.
0. Don’t try calibrating or repairing the meter. When it is indeed necessary for that, only
the qualified professional personnel who have had special training or gained approval
can make it.
. During measurement, the requirement of measurement function must be in accor-
dance with LCD display. Please be sure to disconnect the line of the meter pen with
the measured object first and ensure there is no any input signal. It is forbidden to
switch the function/range selection switch during measurement
2. When “ ” is shown on LCD display, please replace battery immediately to
ensure the measurement precision.
3. It is not allowed to insert the meter pen into the current terminal to measure voltage!
