Hazardous Operating Conditions
1. Do not touch the test area when the Tester’s output is enabled. Electrical shock could
result in physical injury or death.
Be sure to observe the following rules:
• Insure the earth ground is properly connected and use a standard power cord.
• Do not touch the output terminal.
• Do not touch the test wire that is connected to the terminal under test.
• Do not touch any unit under test.
• Do not touch any component that is connected to the output terminal for charging.
• Do not touch the test unit right after the test has ended or when the output has just
been turned off. It can take several seconds for the high voltage to bleed off.
2. Shock accidents usually occur under the following conditions:
• The earth terminal of the Tester is not properly connected.
• Insulating gloves are not used during testing.
• Touching the test unit immediately after the test is done.
3. The high voltage output can be remotely controlled via an external control signal. When
the Tester is being remotely controlled, follow the safety guidelines below:
• Do not allow any accidential high voltage output to cause any danger.
• Do not allow any operator or other personnel to touch the DUT, test cable, or probe
output when high voltage is being output from the scanner.
• Remote control is generally controlled by the high voltage test bar; however, other
control circuits can also be used to control it instead. The test bar is the switch for
controlling high voltage output, so the connected control wire should not be near the
high voltage site and test cable to avoid causing any hazard.
For the precautions and dangerous opeating details, please refer to the
section “Precautions before Use and Installation” in Chapter 3.
