1. Safety Instruction
This instrument is designed according to EN61010-1 Specification. The main
purpose of this Specification is to ensure that the instrument will be used in the
laboratory or the factory safely; it is not suitable for outdoor applications,
especially the moistened or dusty locations. Abnormal use of this instrument may
cause the electrocution hazard. Before using this instrument, please read the
descriptions of this Specification carefully to avoid causing accident due to
incorrect or unintended use.
1.1 Electrocution
To prevent electrocution accident from occurring, it is suggested that the
operator wear insulating rubber globes before working with the machine and
then start the test-related activities.
1.2 Grounding
The back panel of the instrument is fitted with a safe ground terminal. Be sure to
connect this ground terminal to the ground to prevent the operator from
touching the housing as to cause the electrocution.
1.3 Power Source
Power that can be used with this tester is AC 100Vac~240Vac with a frequency
range between 47Hz~63Hz; please confirm whether the input power voltage and
frequency are within range before plugging in the power.

1.4 Connecting the Tester Table to the High Voltage Output Terminal
While the tester is off, connect the high voltage tester cables to the high voltage
output terminal of the tester and make sure that there are no ruptures outside
the cables and that the cables are not loose.
1.5 Warm-up
The instrument will operate normally upon starting the power. To achieve the
specified accuracy, it is suggested warming up the instrument for over 15
minutes.
1.6 External control unit
This unit is able to execute the external control. For this purpose, please ensure
that the operator is not touching the signal output end and the Test Piece to
avoid causing hazard.
1.7 Machine failure
Stop using the instrument immediately when finding it is operating abnormally,
such as significant difference is existed between the current displayed on the
current meter and the design value; or the current is not supplied, but the
overlapping current indicator remains illuminated continuously. In this case,
please contact us or your dealer to provide technical support.
1.8 Ending the test
When not using the instrument, please shut off the Power Switch. To restart the
Power Switch after being disconnected, please wait for few seconds; however,

3
do not execute consecutive on/off action of the power.
1.9 Installation, storage
Normal operating temperature and humidity scope of the instrument is
5oC~40oC and 80% RH respectively, and the instrument may act abnormally if
exceeding such range. The storage temperature and humidity scope of the
instrument is -20oC~ 70oC and 80% RH respectively. To achieve correct testing
and to protect safety, do not install the instrument in the environment exposing
to direct sunshine or high temperature, high humidity, frequency oscillation and
rich dust.
1.10 Emergency treatment
Upon the occurrence of electrocution, burning of the Test Piece or the burning
of Main Unit, please disconnect the Power Switch and remove the power cord
plug immediately to avoid causing a hazard.
