3. Notices before Using

Please read through the notices described in this chapter and memorize them to prevent any
accidents from happening.
Induction and electric shock
■
To avoid electric shock, please check the power of the tester related settings and
descriptions firstly before operating the tester.
Grounding
■
There is a safety grounding terminal at the instrument rear panel. Please use appropriate
test leads and tools to connect the grounding terminal surely. If it is not grounding correctly,
the chassis of test machine may contain high voltage when the power circuit or the
connecting line of any devices short-circuited with the grounding terminal. This is very
dangerous as it may cause electric shock if anyone touches the instrument under the
circumstances. Therefore, it is necessary to connect the safety grounding terminal to earth
correctly.
Remote control system
■
This system is capable of remote control. Usually it uses control signal of rear panel
coordinating with HI-POT series model (such as 1905X, 1907X) to do the high voltage
output control. For your safety and to prevent accidents, the following principles of
control must be performed accurately.
․
Do not allow any unexpected high voltage output to cause any hazards.
․
When the system has high voltage output, operators and other personnel are not
allowed to touch the DUT, test cable and probe and output terminal, etc.
Turn the power switch on or off  Caution 
■
The product should be so positioned that the power switch can be easily reached by the
operator during emergency. Once the power switch is cut off, wait a few seconds to turn it
on again. Do not turn on/off the power switch repeatedly to avoid causing any errors.
Miscellaneous notices
■
Do not short circuit the instrument output line, grounding line, transmission line, or other
connector grounding line, and AC source to avoid the entire test device being charged to a
very dangerous voltage. If the tester is under full load output for a long period, the bottom
partial site of the tester may be high temperature over 50°C. Before moving the tester,
please power the tester off firstly as well as confirm the bottom site of the tester decrease
to below 30°C for avoiding the danger of burning.
Installation notices
■
When installs or operates the tester, the ventilation holes should be at least 10cm from
wall to keep adequate ventilation.
Emergency management
■
In the emergency situations of electric shock, DUT on fire or system on fire, follow the
steps below to avoid causing bigger hazards.
•
First, cut off the power switch.
•
Then, unplug the power cord.
