Chapter 2Precautions on Handling
This chapter describes the precautions to be followed in the handling of this tester.
When using the tester, take utmost care to ensure safety.
！WARNING The tester derives a 5 kV test voltage which can cause human
injury or death. When operating the tester, be extremely careful and observe the
cautions, warnings, and other instructions given in this chapter.
2.1 Prohibited Operations
■ Do not turn on/off the power repeatedly
After turning OFF the power switch, be sure to allow several seconds or more before
turning it ON again. Do not repeat turning ON/OFF the power switch rapidly. If you do
this, the protectors of the tester may not be able to render their protective functions
properly. Do not turn OFF the power switch when the tester is delivering its test
voltage–you may do this only in case of emergency.
■ Do not short the output to the earth ground
Pay attention so that the high test voltage line is not shorted to a nearby AC line or
nearby devices (such as conveyors) which are connected to an earth ground. If it is
shorted, the tester chassis can be charged up to the hazardous high voltage. Be sure to
connect the protective grounding terminal of the tester to an earth line. If this has been
securely done, even when the HIGH VOLTAGE terminal is shorted to the LOW terminal,
the tester will not be damaged and its chassis will not be charged up to the high voltage.
Be sure to use a dedicated tool when grounding the protective grounding terminal.
！CAUTION The term "AC line" here means the line on which the tester is operating.
That is the line to whose outlet the AC power cable of the tester is connected. It
may be of a commercial AC power line or of a private-generator AC power line.
■ Do not apply an External Voltage

TX5012 Series Operation Manual Ver1.0
◇11
Do not apply a voltage from any external device to the output terminals of the tester.
The analog voltmeter on the front panel cannot be used as stand-alone voltmeter.
They may be damaged if their output terminals are subject to an external voltage.
2.2 Action When in Emergency
In case of an emergency (such as electric shock hazard or burning of DUT), take the
following actions. You may do either (a) or (b) first. But be sure to do both.
1.Turn OFF the power switch of the tester.
2.Disconnect the AC power cord of the tester from the AC line receptacle.
2.3 Precautions on Testing
■ Wearing Insulation Gloves
When handling the tester, be sure to wear insulation gloves in order to protect yourself
against high voltages.
■ Precautions for Pausing Tests
When changing test conditions, press the STOP switch once to take precautions. If you
are not going to resume the test soon or if you are leaving the Test area, be sure to
turn-OFF the POWER switch.
■ Items Charged Up to Dangerous High Voltages
When in test, the DUT, test leadwires, probes, and output terminals and their
vicinities can be charged up to dangerous high voltages. Never touch them when in
test.
！WARNING The vinyl sheaths of the alligator clips of the test leadwires which are
supplied accompanying the tester has no sufficient insulation for the high test voltages.
Never touch them when in test.
■ Matters to be Sure of After Turning-OFF Power
If you have to touch the DUT, test leadwires, probes, and/or output terminals and their
vicinities for re-connections or other reasons, be sure of the following two matters.
1. The analog voltmeter indicates “zero.”
2. The DANGER lamp has gone out.

TX5012 Series Operation Manual Ver1.0
◇12
2.4 Dangerous States of Failed Tester
Typical possible dangerous states of the tester are as shown below and in which
cases the most dangerous situation that “the high test voltage remains delivered
and won't be turned off!” may occur. When this situation has occurred,
immediately turn OFF the power switch and disconnect the AC power cable from
the AC line receptacle.
•The DANGER lamp does not go out despite you have pressed the STOP
switch.
•The DANGER lamp does not light up despite the pointer of the analog
voltmeter is deflected indicating that the output voltage is being delivered.
Also when the tester is in other malfunctioning states than the above, there is a
possibility that the output voltage is delivered irrespective of your proper operating
procedure. Never use the tester when it has failed.
！WARNING Keep the tester away of other people until you call our service engineer for
help.
Immediately call DAE KWANG T&M distributor/agent. It is hazardous for an unqualified
person to attempt to troubleshoot any tester problem.
2.5 Daily Checking
To avoid accidents, confirm at least the following before starting operation:
1. The tester is connected to an earth ground.
2. The coating of the high-voltage test lead wire is free from cracks, fissures, and
breakage.
3. The high-voltage test lead wire is not broken.
4. The tester generates FAIL signal when the ends of the low-voltage test lead wire and
high-voltage test lead wire are short-circuited.
