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

100V 120V

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 complete listing of options.

The group test procedure always begins from step 1 to end of group. (e.g. 01~01) The group test procedure always begins from the step selected to end of group. (e.g. 01~03) Disable the function arc detection. Enable the arc detection and stop the test when arc is active.

Enable the arc detection and continue the test when arc is active.

Set the current level of arc detection. Set the AC hi-pot output frequency to 50 Hz. Set the AC hi-pot output frequency to 60 Hz. Control mode of front panel. Mode 1: Reset first (press reset button before test) Mode 2: Press start button directly. Mode 3: REMOTE I/O enable (the start button is disable)

Mode 4 : Reserved. Accept and save all parameters of test step and utility. Refuse to change any parameters of test step and utility. Stop on fail at the DUT detection. Stop on pass at the DUT detection. Reach the time of determination for pass or fail.
