UTION 1 Take sufficient care to not to apply shock vibration or excessive force to the jaw tips Otherwise the precisely adjusted jaw tips will be damaged When a foreign substance is stuck in the jaw tips or they cannot properly engage the transformer jaws do not fully close In such a case do not release the trigger abruptly or attempt to close the transformer jaws by applying external force Make sure that the transformer jaws close by themselves after removing the foreign substance or making them free to move The transformer jaw should be closed in order to achieve accurate measurement When removing the probe from the instrument grasp the plugs not the cable to avoid damaging the cable Use the probe at a distance as far as possible from strong external magnetic field generated from sources below Conductor fed large current Motor Equipment which has magnet Integrating wattmeter 5 1 Measurement Procedure 1 Connect the probe to a digital multimeter whose function set to ACV mV range Input impedance of digital multimeter should be within 1 M to 20 M ohm 2 Open the transformer jaw and clamp a conductor 3 Make sure that the transformer jaw tips are closed fully 5 gasses 8 Be careful about the possible shorting where the jaw tips under test has been exposed to metal parts 9 Never use the probe with wet hands or in a damp environment 10 Do not attempt any modification of original specification
