Safety Summary
The following general safety precautions must be observed during all
phases of operation, service, and repair of this instrument. Failure to
comply with these precautions or specific WARNINGS given elsewhere in
this manual will violate safety standards of design, manufacture, and
intended use of the instrument. Chroma assumes no liability for the
customer’s failure to comply with these requirements.
BEFORE APPLYING POWER
Verify that the power is set to match the rated input of
this power supply.
PROTECTIVE GROUNDING
Make sure to connect the protective grounding to
prevent an electric shock before turning on the
power.
NECESSITY OF PROTECTIVE GROUNDING
Never cut off the internal or external protective
grounding wire, or disconnect the wiring of protective
grounding terminal. Doing so will cause a potential
shock hazard that may bring injury to a person.
FUSES
Only fuses with the required rated current, voltage,
and specified type (normal blow, time delay, etc.)
should be used. Do not use repaired fuses or short-
circuited fuse holders. To do so could cause a
shock or fire hazard.
DO NOT OPERATE INAN EXPLOSIVE ATMOSPHERE
Do not operate the instrument in the presence of
flammable gases or fumes. The instrument should
be used in an environment of good ventilation.
DO NOT REMOVE THE COVER OF THE INSTRUMENT
Operating personnel must not remove the cover of
the instrument. Component replacement and
internal adjustment can be done only by qualified
service personnel.

attention to a procedure, practice, or the like, which,
if not correctly performed or adhered to, could result
in personal injury. Do not proceed beyond a
WARNING sign until the indicated conditions are
fully understood and met.
CAUTION
The CAUTION sign denotes a hazard. It may
result in personal injury or death if not noticed
timely. It calls attention to procedures, practices
and conditions.

The Danger of Operating
1. When the instrument is under output voltage, please don’t touch test
area or you may shock hazard and result in death.
Please obey the following items.
•Make sure the grounding cable is connected correctly and using the
standard power cord.
•Don’t touch the output terminal.
•Don’t touch test cable of connecting test termination.
•Don’t touch test termination object.
•Don’t touch any charge component of connecting output terminal.
•As the instrument end the test or turn off output, please don’t touch
test unit immediately.
2. The shock accidents are usually occurred on the following conditions.
•The grounding terminal of the instrument doesn’t connect correctly.
•No use insulation glove for testing.
•After test is completed to touch test unit immediately.
3. Remote control for the instrument: This instrument provided with
remote control, normally using the external signal to control high
voltage output. For safety reasons and prevent from hazards, please
exactly follow instructions below while using remote control.
•Unexpected high voltage output may exist. Make sure if this
instrument is under testing/remote controlling before access to the
probes.
•When the instrument is under testing/operating, any access to DUT,
test cable and probe output terminal are prohibited, both for the
operator/service personnel.
•Normally remote control of this instrument is controlled by the high
voltage test bar. However, using of other control circuit is also
possible. For safety reasons and prevent from hazards, please
notice that unintentional access to the control test bar or bridging the
control circuit to high voltage terminal and test cables may cause
hazards. Please keep this terminal/control from unintentional
bridging/access to avoid danger.

WARNING Don't tie HV cable, RS232, Handler, GPIB control
cable and other low voltage cable together. Or it
may cause product damaged or PC crashed.

1. Introduction
1.1 An Overview of Function
■ This high quality automatic HiPot test instrument is designed to test the
withstanding leakage current and insulation resistance for electric
machinery and electronic devices.
■ For withstanding test, its output power is AC: 100VA (5kV, 20mA), DC:
30VA (6KV, 5mA), which is applicable to electronic, electric machinery
and components for withstanding and insulation tests.
■ For insulation resistance, its test range is from 0.1MΩ~50GΩ, and test
voltage is 0.050kV ~1kV definable.
■ For ground continue, its test range is from 0Ω∼5Ω.
■ For short/open detection, before testing high voltage test if the
capacitance is short or open circuit in advance. For ensure the DUT is
good contact then to perform high voltage test.
■ All settings for state, time, current, voltage and resistance can be seen
clearly on the display. There is no need to memorize the parameter
state of any items.
■ It is equipped with devices for Pass/Fail judgment, test results and
remote control.
■ It can perform high efficiency and accurate tests for electric machinery,
electronic devices and components.
