Before the replacement, the test leads must leave the measuring 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 test leads 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 gets 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 test leads is inserted into the current socket, don’t measure any voltage for fear that
the meter should be damaged and operator’s safety be endangered.
10.
Don’t try calibrating or repairing the meter. When necessary, only the qualified professional
personnel who have had special training or gained approval can make it.
11.
During measurement, the requirement of measurement function must be in accordance with
LCD display. Please be sure to disconnect the line of the test leads 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.
12.
When “
” is show on LCD display, please replace battery immediately to ensure the
measurement precision.
13.
It is not allowed to insert the test leads into the current terminal to measure voltage!
14.
Please don’t change the circuits of the meter freely for fear that the meter be damaged and the
safety be endangered.
