LCR-T4 MEGA428 Component tester ESR meter LCD display

LCR-T4 MEGA428 Component tester ESR meter LCD display

Operation:

• The meter measures the voltage across and the current through the DUT.
• From the ratio of these the meter can determine the magnitude of the impedance. In combination with the impedance.
• The equivalent capacitance or inductance, and resistance, of the DUT can be calculated and displayed.
• All real capacitors have a little inductance, a little resistance, and some defects causing inefficiency.
• The most useful assumption, and the one usually adopted, is that LR measurements have the elements in series and that CR measurements have the elements in parallel.
• Handheld LCR meters typically have selectable test frequencies of 100 Hz, 120 Hz, 1 kHz, 10 kHz, and 100 kHz for top end meters.
• The display resolution and measurement range capability will typically change with the applied test frequency since the circuitry is more sensitive or less for a given component
