When selecting an Earth Bond Test and setting the Test Current parameter to 100mA, the test can be performed in one of two ways. A Fast key IN_SITU TEST (which becomes ISOLATED TEST to return to the previous test mode) enables the user to select an In-Situ test
This is an Earth Bond Test where the EUT is not plugged into the Tester power socket but remains powered up from its normal power socket. For this test to be correctly carried out, the Supernova Plus 37
is required to be powered from an adjacent socket to the EUTs power socket. There are two stages to this test: 5. An Earth Bond Test to the socket earth. This is carried out by connecting the Earth Bond lead to the socket screw (which should be earthed) or an adjacent building earth to the EUT. Press the Green button to activate the test. No Pass or Fail will be displayed for this test. 6. An Earth Bond Test to the EUT is now required. This is carried out by connecting the Earth Bond lead to the EUT earthed cover. Press the Green button to activate the test. After the test the result of the Earth Bond Test will be displayed.
Earth Bond tests have an additional Fast Key; LIMIT CALC. Selecting this enables the User to set an accurate Earth Bond Test limit by specifying the cable parameters.
In Situ Touch Leakage Test
The Touch Leakage Test can be performed without powering down the EUT and plugging it into the tester power socket. The only connection the User is required to make is to connect the Earth Bond Test lead to the exposed metal work of the EUT and then perform the test.
Note When the connection icon is flashing you cannot change any settings. The settings cannot be changed for a test if you have performed that test from within an appliance sequence. For example after selecting Create Appliance No you can only change the Earth Bond settings on the first Earth Bond test, all subsequent Earth Bond test will conform to the same settings. Press the Enter button to start the test. Press the Red button to abort the test at any time. Note In manual mode you will not get Abort Options, the test will simply stop the test and revert to the Meter display. The aborted test will not be stored. If an Appliance Number has been created, the test result will be stored under the entered Appliance number.

If this message appears, the Supernova Plus is faulty and requires repair. Contact your Seaward Agent for repair. If the low voltage test fails, then either of the following warnings will be displayed:--------------------WARNING-------------------APPLIANCE MAY BE SHORT CIRCUIT PRESS THE ENTER BUTTON IF SAFE PRESS THE RED BUTTON TO ABORT --------------------WARNING-------------------FUSE MAY BE OPEN CIRCUIT OR PRESS THE ENTER BUTTON IF SAFE PRESS THE RED BUTTON TO ABORT
These messages mean that the EUT is switched off or the fuse may be open circuit, or it maybe possible that the EUT will draw more than 18A and could damage the Tester. User discretion is required. If in doubt abort the test and seek advice.

Temperature monitoring

The tester is provided with internal temperature monitors to ensure sensitive components are not overheated. High rates of testing may cause this situation, especially with long duration Earth Bond tests. Setting Earth Bond test duration to 2 secs will increase operating time. If the following message appears, leave the tester to cool down before pressing Enter to continue testing. WARNING THE TEST HAS BEEN ABORTED BECAUSE THE APPLIANCE TESTER BECAME TOO HOT. ALLOW THE UNIT TO COOL BEFORE STARTING PRESS ENTER BUTTON TO CONTINUE
Multiple Earth connections:
In general, multiple earth connections to an EUT (e.g. water pipe connections to a water heater) can cause difficulties in measurement. This has previously needed the additional earth connections to be isolated. The Supernova Plus tester is capable of testing earth connections in the presence of additional earth paths. This is done automatically by performing a point to point measurement of the earth connection, and measurement of the differential leakage current, rather than the earth lead current. Measurements are thus assured without special precautions.

Barcodes

Barcode Scanner Specification
The Supernova Plus Tester can be used with barcodes and barcode scanners, readers or wands compatible with other Seaward PAT testers These connect to the serial (RS232) connector The required barcode reader / scanner configuration is as follows:Baud Rate: Start Bits: 69

Interfacing

Data Bits Stop Bits: Parity: Inter-character Delay: None 20ms
When to use a Barcode Scanner

The Tester provides two interfacing ports:A Serial Port - for connection to a PC, Printer, Barcode Reader/Scanner, Modem, Brain Cell Reader Also provided with the Tester is a Dual Serial Port Adaptor. This adaptor enables two accessories to be connected to the serial port of the Tester at the same time. The grey socket in the dual side of the adaptor is to plug in input devices e.g. Barcode Reader/Scanners. The black socket in the dual side of the adaptor is for output devices e.g. downloading to PC, Printers or Z-Modem. Note A Brain Cell Reader cannot be used with the Dual Serial Port Adaptor. The Reader needs to be plugged directly into the Tester serial port.

Appendix A Purpose of Tests
This test is to ensure that the connection between the earth pin in the mains plug of the appliance and the metal casing of the appliance is satisfactory and of sufficiently low resistance. A selectable test current is applied between the earth pin of the mains supply plug and the earth bond test lead clip. A high current is normally used to stress the connection under fault conditions. The length of the test should be limited to prevent damage due to overheating.
This test is to check the earth screen connection using a current which will prevent damage that may be caused by testing using high currents. This is often required by sensitive electronics such as computers and other Information Technology (IT) equipment. A low voltage of approximately 100mV AC RMS is applied between the earth pin of the mains supply plug and the Earth Bond test lead clip. A current of 100mA is allowed to flow for the duration of the test.
500 V / 250V d.c. test voltage This test is used to verify that adequate insulation exists between the mains supply pins and earth.
During the insulation test, a 500V DC voltage is applied between the earth pin and both the live and neutral pins of the appliance mains supply plug. The Tester displays the resistance measured and allows the user to confirm sufficient insulation exists. For Class 2 appliances, the Earth Bond Test clip can be used for an earth return lead. For appliances which incorporate over-voltage protection, a 250V DC test voltage is provided to allow a reading to be taken without the protection devices generating a false failure.
The substitute leakage test applies a nominal voltage of 40V AC RMS to the appliance and is applied between the earth pin and both the live and neutral pins of the supply plug. For Class II appliances, connect the Earth Bond test clip to the appliance as a substitute for the Earth. The Tester measures the current that flows and scales the result to display a guide to the current that would flow if the test voltage had been the nominal mains supply voltage, scaled for the applicable socket. Please note that values for Substitute Leakage may differ substantially from that of conventional Earth Leakage tests because of the way that the test is performed (e.g. it will be affected by the presence of Neutral-to-Earth suppression capacitors). This test can prove useful in situations where neither conventional Insulation nor Flash tests are acceptable methods of testing the insulation of the appliance.

Mains voltage applied to appliance The Touch Test displays the current that would flow if the appliance was touched by a person. This is based on a body model of 2k. The Tester detects any current flowing in the Earth Bond Lead (attached to an appropriate point on the appliance) and indicates the potential leakage through a metal panel. The Tester displays the result in milliamps (mA).

Operation Test

Mains voltage applied to appliance The Power test supplies the equipment under test (appliance), connected to 115V/230V test sockets, with the rated voltage of that socket. The Tester measures the power used by the appliance and displays the reading in kVA. There is no test duration limit on the Power tests. Once supplied with power, the appliance will be supplied until the operation is cancelled. This will allow appliances with slow start-up speeds the time to ramp up to their working state.
