Page 3: 1．Safe Testing
1. SAFE TESTING Electricity is dangerous and can cause injury and death. Always treat it with the greatest of respect and care. If you are not quite sure how to proceed, stop and take advice from a qualified person. 1. This instrument must only be used by a competent and trained person and operated in strict accordance with the instructions. - Page 4 barriers on the test leads. 11. During testing it is possible that there may be a momentary degradation of the reading due to the presence of excessive transients or discharges on the electrical system under test. Should this be observed, the test must be repeated to obtain a correct reading.

Page 12: 4．Continuity (Resistance) Tests
This measurement should not include the resistance of any test leads used. The resistance of the test leads needs to be subtracted from any continuity measurement. Model 6011A is provided with a continuity null feature which allows automatic compensation for any test lead resistance. - Page 13 Fig 3 Model 6011A is provided with a facility to change the polarity of the test current used by the instrument during continuity tests. This can overcome affects caused by the polarisation of the installation during testing which may give inaccurate readings.

Page 14: 5．Insulation Tests
This charge must be removed from the system at the end of the test, a function which is automatically performed by Model 6011A. If an alternating voltage is applied between the conductors, the system continuously charges and discharges as the applied voltage alternates, so that there is a continuous alternating leakage current flowing to the system. -
Page 15: 5． 1． 3 Conduction Current
Fig 4 5． 1． 3 Conduction Current Since the insulation resistance is not infinite, a small leakage current flows through the insulation between conductors. Since Ohm's Law applies, the leakage current can be calculated from Leakage current (μA) = applied voltage (V) insulation resistance (MΩ) Fig 5 5．... -
Page 16: 5． 1． 5 Total Leakage Current
The system is charged to the full test voltage, and will be dangerous if left with this charge. Model 6011A provides an automatic path for discharging current as soon as the test button is released to ensure that the circuit under test is safely discharged. -
Page 17: 5． 3 Preparation For Measurement
5． 4 Insulation resistance measurement Model 6011A has a selectable, triple test voltage of 250V, 500V and 1000V DC. 1． Select the insulation resistance setting by rotating the function dial to the required test voltage - 250V, 500V or 1000V as indicated under the “insulation”test section of the functional switch, after making sure that the... - Page 18 Fig 7 Note:Insulation testing must only be undertaken on de-energised circuits. 3． If the mains warning lamp lights and/or the buzzer sounds DO NOT PRESS THE TEST BUTTON but disconnect the instrument from the circuit. Make the circuit dead before proceeding. Fig 8 4．...
- Page 19 6． When testing is complete release the test button BEFORE disconnecting the test leads from the circuit or from the appliance. This will ensure that the charge built up by the circuit or the appliance during insulation test is dissipated in the discharge circuit. In the discharging process, an LED illuminates and the live circuit warning buzzer will sound.

Page 22: 6． 5 Loop Impedance At 3 Phase Equipment
6.5 Loop impedance at 3 phase equipment In order to test the Loop impedance at 3 phase equipment the optional OMA DIEC(Model7133B) is necessary. Use the same procedure as in 6.4 above ensuring that only one phase is connected at a time i.e.： First Test: red prod to phase 1, black prod to neutral, green crocodile clip to earth. -

1．Select the 200A, 2000A or 20kA range. 2． Connect the OMA DIEC(Model7133B) distribution board lead to the IEC socket on the instrument. 3． Connect the red phase probe of the OMA DIEC(Model7133B) to the phase of the system, the black probe to the neutral of the system and the green crocodile clip to the neutral of the system. -
Page 25: 8． 2 What Does The Rcd Test Really Do
8.2 What does the RCD test really do? The RCD is designed to trip out when the difference between the phase current and the neutral current (this is called the residual current) reaches the tripping value (or rating) of the device. The tester provides a carefully preset value of residual current depending on its setting and then measures the time lapse between the application of the current and the operation of the RCD. -
Page 26: 8． 6 Testing Rcd's Used To Provide Supplementary Protection
4． Connect the instrument to the RCD to be tested either via a suitable socket outlet（see fig 9）or using the OMA DIEC(Model7133B) test lead set（see fig 10）. 5． Make sure that the P-E and P-N wiring check lamps are lit and the wiring incorrect LED is not lit. -

Page 29: 10．General
10. GENERAL The test button can be locked down for ease of use by pressing it and turning clockwise. Do not forget to release test button by turning it counterclockwise before disconnecting the instrument from the test points. Failure to do so may leave the tested circuit in a charged condition when carrying out insulation test. -
Page 30: 13．Servicing
If the instrument will not operate in the loop impedance, PSC and RCD modes, it may be that the protective fuses fitted on the printed circuit board have blown. If you suspect that the fuses have failed, return the instrument to your distributor for service - do not attempt to replace the fuses yourself. -
