(Pollution Degree) EN 61010-1:2010 specifies the pollution degrees and their requirements as follows. The GPT-9000 falls under degree
2.
Pollution refers to “addition of foreign matter, solid, liquid, or
gaseous (ionized gases), that may produce a reduction of dielectric strength or surface resistivity”.
Pollution degree 1: No pollution or only dry, non-conductive
pollution occurs. The pollution has no influence.
Pollution degree 2: Normally only non-conductive pollution
occurs. Occasionally, however, a temporary conductivity caused by condensation must be expected.
Pollution degree 3: Conductive pollution occurs, or dry, non-
conductive pollution occurs which becomes conductive due to condensation which is expected. In such conditions, equipment is normally protected against exposure to direct sunlight, precipitation, and full wind pressure, but neither temperature nor humidity is controlled.
Storage environment

NOTE: This lead/appliance must only be wired by competent persons
WARNING: THIS APPLIANCE MUST BE EARTHED IMPORTANT: The wires in this lead are coloured in accordance with the following code:
As the colours of the wires in main leads may not correspond with the coloured marking identified in your plug/appliance, proceed as follows:
The wire which is coloured Green & Yellow must be connected to the Earth terminal marked with either the letter E, the earth symbol
or coloured Green/Green & Yellow.
The wire which is coloured Blue must be connected to the terminal which is marked with the letter N or coloured Blue or Black.
The wire which is coloured Brown must be connected to the terminal marked with the letter L or P or coloured Brown or Red.
If in doubt, consult the instructions provided with the equipment or contact the supplier.
This cable/appliance should be protected by a suitably rated and approved HBC mains fuse: refer to the rating information on the equipment and/or user instructions for details. As a guide, a cable of 0.75mm2 should be protected by a 3A or 5A fuse. Larger conductors would normally require 13A types, depending on the connection method used.
Any exposed wiring from a cable, plug or connection that is engaged in a live socket is extremely hazardous. If a cable or plug is deemed hazardous, turn off the mains power and remove the cable, any fuses and fuse assemblies. All hazardous wiring must be immediately destroyed and replaced in accordance to the above standard.

The GPT-9000 is a high voltage instrument that outputs dangerous voltages. The following section describes precautions and procedures that must be followed to ensure a safe work environment.
WARNING
The GPT-9000 generates voltages in excess of 5kVAC or 6kVDC. Follow all safety precautions, warnings and directions given in the following section when using the GPT-9000.
1. Only technically qualified personnel should be
allowed to operate the safety tester.
2. The operating workplace must be fully isolated,
especially when the instrument is in operation. The instrument should be clearly labeled with appropriate warning signage.
3. The operator should not wear any conductive
materials, jewelry, badges, or other items, such wrist watches.
4. The operator should wear insulation gloves for
high voltage protection.

Workplace Precautions

25
GPT-9000 Series User Manual
Background
The GPT-9000 is a high voltage instrument that outputs dangerous voltages. The following section describes precautions and procedures that must be followed to ensure that the tester is operated in a safe manner.
WARNING
The GPT-9000 generates voltages of up to 5kVAC or 6kVDC. Follow all safety precautions, warnings and directions given in the following section when using the GPT-9000.
1. Never touch the safety tester, lead wires,
terminals, probes and other connected equipment when the tester is testing.
2. Do not turn the safety tester on and off quickly
or repeatedly. When turning the power off, please allow a few moments before turning the power back on. This will allow the protection circuits to properly initialize.
Do not turn the power off when a test is running, unless in an emergency.
3. Only use those test leads supplied with the
instrument. Leads with inappropriate gauges can be dangerous to both the operator and the instrument. For GB testing, never use the Sense leads on the SOURCE terminals.
4. Do not short the HIGH VOLTAGE terminal
with ground. Doing so could charge the chassis to dangerously high voltages.

Operating Precautions

26
GETTING STARTED
5. Ensure the earth ground of the line voltage is
properly grounded.
6. Only connect the test leads to the HIGH
VOLTAGE/SOURCE H/SENSE H terminals before the start of a test. Keep the test leads disconnected at all other times.
7. Always press the STOP button when pausing
testing.
8. Do not leave the safety tester unattended.
Always turn the power off when leaving the testing area.
9. When remotely controlling the safety tester,
ensure adequate safety measures are in place to prevent:
Inadvertent output of the test voltage.
Accidental contact with the instrument during
testing. Ensure that the instrument and DUT are fully isolated when the instrument is remotely controlled.
10. Ensure an adequate discharge time for the
DUT.
When DCW or IR tests are performed, the DUT, test leads and probes become highly charged. The GPT-9000 has discharge circuitry to discharge the DUT after each test. The time required for a DUT to discharge depends on the DUT and test voltage.
Never disconnect the safety tester before a discharge is completed.
27
GPT-9000 Series User Manual
Background
The GPT-9000 is a high voltage device and as such, daily safety checks should be made to ensure safe operation.
1. Ensure all test leads are not broken and are free
from defects such as cracks or splitting.
2. Ensure the safety tester is always connected to
an earth ground.
3. Test the safety tester operation with a low
voltage/current output: Ensure the safety tester generates a FAIL judgment when the HIGH VOLTAGE and RETURN terminals are shorted (using the lowest voltage/current as the testing parameters).
WARNING
Do not use high voltages/currents when the HIGH VOLTAGE and RETURN terminals are shorted. It may result in damage to the instrument.

The TIMER setting is used to set the test time for the current test. The test time determines how long the test voltage or current is applied to the DUT. This test time does not include Ramp , initial start time or discharge time (note: GB does not have Ramp or discharge times). The test time can be set from 0.5 seconds to 999.9 seconds for ACW, DCW and GB and
1.0 second to 999.9 seconds for IR, with a resolution of 0.1 seconds for all modes. The timer can be turned off when in the special MANU test mode when using the ACW or DCW test functions.
Each test has an initial test time of 100ms and a discharge time (except GB). The total discharge time depends on the DUT and test voltage.

With the ACW test function, when the test current is between 30mA and 40mA (GPT-98XX) or 80mA and 100mA (GPT-99XX), the ramp time + test time cannot exceed 240 seconds. At this current level, the tester also needs to pause after a test for a time equal to or greater than the output time. See the specifications on page 161 for details.

Background
ARC detection, otherwise known as flashover detection, detects fast voltage or current transients that are not normally detected. Arcing is usually an indicator of poor withstanding insulation, electrode gaps or other insulating problems that cause temporary spikes in current or voltage during ACW and DCW testing.
There are three ARC detection settings: OFF, ON AND CONTINUE, ON AND STOP. The ON AND CONTINUE setting will detect arcs over the ARC current level and continue the test, the ON AND STOP setting will stop the test when an arc is detected.
ARC mode settings only apply to ACW and DCW tests.
Steps
1. Press the UTILITY key on the front
panel when the tester is in EDIT status. The tester will go to the MANU Utility for the current test.

Background
When GROUND MODE is set to ON, the GPT­9000 grounds the return terminal to the ground. This mode is best for DUTs that are grounded to an earth ground by their chassis, fixtures or operation environment. This mode measures the potential of the HIGH VOLTAGE terminal with respect to earth ground. This means that any stray capacitance/resistance that leaks to earth ground will also be measured. This is the safest testing mode, though potentially not as accurate.
When GROUND MODE is set to OFF, the return terminal is floating with respect to the earth ground. This mode is for DUTs that are floating and not directly connected to an earth ground. This is more accurate than when GROUND MODE is set to ON as any stray capacitance/resistance that leaks to the earth

Special Test Mode Overview
When MANU number 000 is selected, the special test mode is activated. Under the special test mode, the voltage can be changed during a test, in real time (ACW, DCW only). The test function can also be changed when in READY or VIEW status, unlike under normal operation.
Separate settings can be saved under the special test mode for each of the testing functions: ACW, DCW, IR and GB. This means a different ACW, DCW, IR and GB test setup can be saved for MANU number 000.
Sweep Function Overview
The GPT-9903 and 9904 also has access to the sweep mode function. The sweep function creates a graph of one of the ACW, DCW, IR or GB tests in the special manual mode. The graph will plot the output voltage, current or resistance versus time. After the test has been completed, the test current, voltage or resistance at any point in time can be viewed in the graph.
Below is an example of the resultant sweep plot of a DCW test where a DC voltage is ramped up to a user-defined level until the HI SET current level has been tripped or the test time runs out.

Description
The Control settings are accessed in the COMMON UTILITY menu. The Control settings include: Start Control, Double Action, Key Lock and Interlock.
Start Control is used to determine how a test is started. Tests can be started via the front panel (START/STOP buttons), from a remote controller or via the SIGNAL I/O port.
The Double Action function is a safety feature used to prevent accidentally starting a test. Normally to start a test, the START button is pressed when the tester is in the READY status. To start a test when Double Action is ON, the STOP button must first be pressed, followed by the START button within 500ms.
Key Lock disables the front panel keys from changing the test number, mode or testing parameters. Only the Utility menu and any keys required for testing are not disabled.
