Ⅲ
. Safety Note
In accordance with IEC1010 clause (the safety standard issued by International Electrotechnical Commission), IT is
designed and produced according to the safety requirements of pollution level
Ⅱ
.
Warning:
In order to avoid endangering the operator’s safety, prior to the operation of the instrument, please read the instruction
manual carefully, and conform to the safety warning information and operation instruction strictly to use the instrument.
1.
When voltage above 30V, current above 10mA, AC power line with inductive load or power line during electric
fluctuation is measured, please beware of electric shock.
2.
Prior to measurement, check if the measurement function is in conformity with the LCD display, and if the
pushbutton 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 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.
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.
10.
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.
11.
During measurement, the requirement of measurement function must be in accordance 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
12.
When

is shown on LCD display, please replace battery immediately to ensure the measurement precision.
13.
It is not allowed to insert the meter pen 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.
