1. Do not use the instrument in areas subject to rapid temperature fluctuations e The clamping JAWS is precision assembled to ensure high performance When using the clamp do not apply any intense mechanical shock vibration or force to the clamping JAWS If dust or any other foreign matter gets in the clamping JAWS do not close the clamping cores tight First remove the dust and then make sure the clamping cores on both sides close smoothly Measuring Method O O OOOO N CAUTION m To avoid damage to instrument Do not apply a current exceeding the maximum allowable current as this may cause damage to the instrument 1 Turn the digital multimeter s power on and then set the function switch to AC V 2 Connect the lead plugs from the clamp probe to the digital multimeter input terminals In this case connect the red plug to terminal V the black plug to terminal com 3 Squeeze on the Open Close lever to open the clamping JAWS and clamp one of the wires to be measured Make sure that the end of the clamp is closed securely 4 Read the indication value of the digital multimeter lt The current value calculation gt Example When the output voltage is 150 0 mV Current 1 e 15 00A For Precise Measurements e Clamp only one wire Clamping a tough rubber sheathed cable and a parallel PVC cable together disables measurement e When performing a measurement hold the probe so that the measured conductor2.
