DocumentDocumentMPU690 Proving Unit User Guide Introduction The MPU690 Proving Unit safely generates high voltages to energise 2 pole voltage testers thus allowing verification of their correct operation. The unit will also test voltage testers that use a pygmy lamp. Features include automatic power on when voltage tester probes are inserted into the output terminals, 50Hz test voltage to simulate AC mains supply and a magnetic back to the case. Instructions To activate the MPU690 firstly insert the voltage tester flying lead probe into the right hand terminal followed by the voltage tester fixed probe into the left hand terminal. Gently apply and maintain pressure to the left hand probe to activate the internal power switch. The test voltage is transmitted to the voltage tester. The test voltage LEDs will automatically ramp up to 690 volts and then slowly ramp back down 690 V - 400 V - 230 V - 100 V - 50 V - OFF (to re-test slightly lift the left-hand probe and re-apply the pressure). The advantages of the auto test function are: 1. Individual voltages are applied at five key voltage test points with significant battery savings as power is automatically switched off when the test is completed. 2. Once the voltage tester has been proved to be correctly functioning you may carry out testing circuits. It is recommended that a voltage tester be verified regularly. G Safety Warnings Risk of electric shock Safety Warnings must be read and understood before instrument is used. As this unit generates voltages up to 690 volts caution should be exercised, hands should remain behind guards of applied voltage detectors. Never connect to installation wiring. Only voltage testers should be connected to the proving unit. Never insert wire, nails or screwdrivers into either terminal. Do not force objects into the left hand terminal to enable permanent operation. Ensure the unit is free from moisture, grease and dust; clean unit with a soft dry cloth only. Do not use if there is any damage to the MPU690. The battery cover must be in place whilst conducting tests. Note: This instrument must only be used by suitably trained and competent persons. Safety Warnings cont. CATIV Measurement category IV: Equipment connected between the origin of the low-voltage mains supply outside the building and the consumer unit. CATIII Measurement category III: Equipment connected between the consumer unit and the electrical outlets. CATII Measurement category II: Equipment connected between the electrical outlets and the user's equipment. End of life disposal WEEE Directive The crossed out wheeled bin symbol on the instrument and on the batteries is a reminder not to dispose of them with general waste at the end of their life.
