NOTE: This lead/appliance must only be wired by competent
persons.
WARNING: THIS APPLIANCE MUST BE EARTHED
IMPORTANT: The wires in this lead are colo ured in a cco r da n c e
with the following code:
Green/ Yellow: Earth
Blue: Neutral
Brown: Live (Phase)
As the colours of the wires in main leads may not correspond
with the colours marking identified in your plug/appliance,
proceed as follows:
The wire which is coloured Green & Yellow must be connected
to the Earth terminal marked with the letter E or by the earth
symbol
or coloured Green or Green & Yellow.
The wire which is coloured Brown must be connected to the
terminal marked with the letter L or P or coloured Brown or
Red.
If in doubt, consult the instructions provided with the equipment
or contact the supplier.
This cable/appliance should be protected by a suitably rated and
approved HBC mains fuse: refer to the rating information on
the equipment and/or user instructions for details. As a guide,
cable of 0.75mm
2
should be protected by a 3A or 5A fuse. Larger
conductors would normally require 13A types, depending on the
connection method used.
Any moulded mains connector that requires removal
/replacement must be destroyed by removal of any fuse & fuse
carrier and disposed of immediately, as a plug with bared wires
is hazardous if a engaged in live socket. Any re-wiring mu st be
carried out in accordance with the information detailed on this
label.
The wire which is coloured Blue must be connected to the
terminal which is marked with the letter N or coloured Blue or

3. PRECAUTIONS BEFORE OPERATION
3-1. Unpacking the instrument
The product has been fully inspected and tested before shipping
from the factory. Upon receiving the instrument, please unpack and
inspect it to check if there is any damage caused during
transportation. If any sign of damage is found, notify the bearer
and/or the dealer immediately.
3-2. Safety Notice
Working place
The working place must be isolated and when the high voltage is
proceeding, it should be alerted with a warning sign of dangerous
for special caution.
Checking the Line Voltage
The instruments can be applied with any kind of line voltage shown
in the table below. Before connecting the power plug to an AC line
outlet, make sure the voltage selector of the rear panel is set to the
correct position corresponding to the line voltage. It might be
damaged the instrument if connected to the wrong AC line voltage.
WARNING. To avoid electrical shock the power cord
protective grounding conductor must be connected to
ground.
The equipment shall not be used for measurements
within category II, III and IV.

Secure Testing
Never operate the tester in the place with electric circuit device
around.
The earth lead should be well connected in accordance with
instruction. The Return Lead has to be connected to the tested object
first before linking up test probe. Connect the test probe to the high
voltage output terminal ONLY when conducting tests. Otherwise,
keep the probe disconnected from the tester. Also, do not touch the
electric conductor of test probe and the operator has to fully control
the power on/off by using switch or remote control, which should not
be lay aside carelessly.
WARNING: During the testing, do not touch the tested
object or any other connec t ed objects.

Set the Scanner Box to output and return function
through the setting of Hi and Lo. If the setting is
Hi=01 and Lo=02, that means the high voltage is
output from CH1 and return from CH2. If Hi and Lo
are set to 00, that means no signal is sent to Scanner
Box.
＊ When the measured load becomes capacitive, the test time must be
extended.
＊ Ramp Time
Ramp Time setting provides a fast and safe way to detect short circuit
or faulty wiring of your Device Under Test.
GPT/GPI-700A monitors the voltage level during the first stage of
Ramp Time to find out short condition. If the voltage still remains
less than 50V after 0.1s, GPT/GPI-700A cuts off the output and
displays the message “Short”. Therefore the short current will be shut
off before it grows beyond Imax, the current limit setting.
When checking GPT/GPI-700A current accuracy, if the DUT has less
than 2Mohm input impedance, turn off the Ramp Time setting.
GPT/GPI-700A may shut down the voltage taking the low impedance
as a sign of short circuit.

5-3. Structure of storage steps
The storage steps of EST are total 10 groups (group 0 ~ group 9), 16
steps (step 01 ~ step 16) for each group. Except these steps, there is another
step “COM” for special test. The presentation of storage steps is Group: Step.
The first number represents group while the second represents step.
