Intelligent Inductance Capacitance Meter LCR Tester Instrument Operation
1. Measuring capacitors
1. Connect one end of the test voltage cable to the "Voltage Output" 25V terminal, and the cable clamps at the other end to the connecting busbars on both poles of the capacitor bank under test.
2. Plug the test current signal cable into the "Current Input" input plug, and connect the other end to the clamp meter. Pay attention to the direction of the clamp meter's jaws. The red clip of the voltage line and the front panel (with display) of the clamp ammeter are of the same polarity. If connected in reverse, the sign of the phase angle between voltage and current will be incorrect, and the instrument cannot correctly identify whether the test object is capacitive or inductive.
4. Use the "↑" and "↓" keys in combination; the screen cycles through: Auto, Capacitance, Inductance, Resistance, to set the test object type. Normally, use the default mode: Auto. The instrument determines the test object type based on the phase difference between test voltage and current. In some cases, because the capacitance of the test object is too small (below the instrument's lower measurement limit), the instrument can accurately read the effective current value but cannot measure the phase angle, making it impossible to determine the test object type. In such cases, the user needs to manually set the test object type.
After setting the test object type, press the "→" key to move the cursor to "Voltage Level". Use the "↑" and "↓" keys in combination; the screen cycles through: 0.38/ kV, 6.6kV, 6.6/ kV, 10kV, 10/ kV, 11kV, 11/ kV, 12kV, 12/ kV, 35kV, 35/ kV. Selecting the voltage value is for calculating the kvar of the capacitor and does not affect the capacitance value.
