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 for any damage that may have occurred during transportation. If
any sign of damage is found, notify the carrier and Vitrek or your distributor immediately.
3-2. Safety Notice
Work Place Safety
The work place must be isolated from routine traffic and when high voltage testing is in process, a
warning signal should be provided.
Checking the Line Voltage
The instrument can be connected to 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 on the rear panel is set to the correct
position corresponding to the line voltage. CAUTION: Damage to the instrument may occur if it is
connected to the wrong AC line voltage.
WARNING. To avoid electrical shock the power cord protective grounding conductor must be
connected to ground.
When line voltage is changed, install the required fuses shown as below:
Line voltage Range Fuse Line voltage Range Fuse
100V
120V
90-110V
108-132V
T 7.0A
250V
220V
230V
198-242V
207-250V
T 7.0A
250V
WARNING. To avoid personal injury, disconnect the power cord before removing the fuse holder.
Operator’s Precaution
(1) Because of the extreme high output voltage and current of the breakdown tester, only a qualified person
should operate the tester in order to avoid fatal electric shock.
(2) On-the-job training is required for the operator to use the tester efficiently and safely.
(3) The operator should be prohibited from wearing metal jewelry, etc in order to avoid an electrical shock.
(4) A person with a heart condition or who wears a pacemaker must not operate the tester.
Safe, Secure Testing
The earth ground contact of the power cord must be properly connected in accordance with instructions.
The return lead must be connected to the tested object first before high voltage testing. Do not handle the
alligator test leads while high voltage is applied. Also, when using the optional HV probe do not touch the
exposed conductive tip of the test probe during testing. Provide full control the power supplied to the
tester by means of a carefully placed on/off switch or remote power control device.
WARNING: During testing, do not touch the test object or any other connected objects.
3-3.Environment
The normal ambient temperature range of this instrument is from 0°to 40°C (32°to 104°F). Operation of
the instrument above this specific temperature range may cause damage to the circuits.

*The arc detection circuit is tuned for high frequencies. It does not see any line frequency energy. Arcs are a
wide band phenomenon and are not required for electrical safety testing, so it is safe to disable this feature. It
is there primarily as a QC feature above and beyond the safety requirement. The safety spec is checking for
electrical breakdown of the primary insulation. Breakdown is defined by UL as a sudden and uncontrolled
flow of current. Since an arc tends to be a controlled flow of current it is not considered a breakdown.
Please note that the Utility menu is context sensitive—that is, the options available are contingent upon
which test is currently ready to be run. For example, if you have an ACW test ready, you will have the Arc
Mode and Current selections available to you, but not the IR Test Mode or GB Zero Check selections. To set
these, select either an IR or a GB test, respectively. The Group Test, Test Control Mode, Data Lock, Interface,
and Fail Setting options are available regardless of what test is selected. Refer to the following table for a

The special test step “COM” contains another two types of test: CAC and CDC. The function of CAC (CDC)
is as same as ACW (DCW), except user could adjust the output voltage during test.
After each step has been tested, the tested status will be shown on the screen:

5-4. Menu Parameter Setup
zAC/DC Hipot – Voltage withstand test (ACW/DCW)
Press MENU key to enter MENU mode then use knob and arrow keys to select a step.
Press EDIT/SAVE key to enter EDIT mode. The cursor stays at the “test mode” field. Use knob to
select desired test ACW (DCW).
Functionality of FIELD key:
Press FIELD key to edit the next field “output voltage”. Use the knob to adjust the desired output
voltage while using the arrow keys to adjust the knob’s resolution (0.100~ 5.000 kV for ACW, 0.100~
6.000 kV for DCW).
Press FIELD key again to enter the next field “measurement upper limit”. Use the knob to adjust the
desired upper limit of leakage current while using the arrow keys to adjust the knob’s resolution
(0.10~15mA for ACW, 0.10~7.5mA for DCW).
Press FIELD key again to enter the next field “measurement lower limit”. Use the knob to adjust the
desired lower limit of leakage current while using the arrow keys to adjust the knob’s resolution
(0.10~15mA for ACW, 0.10~7.5mA for DCW).
Press FIELD key again to enter the next field “ramping time”. Use the knob to adjust the desired
ramping time while using the arrow keys to adjust the knob’s resolution (0~999.9s).
Press FIELD key again to enter the next field “testing time”. Use the knob to adjust the desired testing
time while using the arrow keys to adjust the knob’s resolution (0~999.9s).
Press FIELD key again to return to the first field “test mode” again.
Press EDIT/SAVE key to save all the parameters.
zContinuous AC/DC withstanding voltage test (CAC/CDC)
The CAC/CDC test is available only on “COM”. Like the traditional hipot tester, you can use the knob
and arrow keys to adjust output voltage during the test.
All the parameters of CAC/CDC are the same as ACW/DCW, except the testing time. The testing of
CAC/CDC is not limited.
