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

Product Applications
LCR-T4 MEGA428 Component tester ESR meter LCD display
- LCD12864 large screen display
- Support boot voltage detection function
- Automatic detection of NPN and PNP transistors, N-channel and P-channel MOSFETs, diodes (including dual diodes), thyristors, transistors, resistors and capacitors.
- The pin of the component is automatically tested and displayed on the LCD.
- Higher test speed, valid component test is 2 seconds. (Except for larger capacitors, the measurement of large capacitors also takes a long time, and the measurement time of 1 minute is normal).
- Automatic shutdown function can avoid unnecessary waste, save battery energy and improve battery life.
- One-button operation automatically turns off the power.
- The ATmega328 uses sleep mode to reduce power consumption when not in measurement.
Cautions:
- Discharge the capacitors completely before you measure it, otherwise, it could damage your meter.
- Considering the accuracy of testing, please replace batteries when battery power is low.
- Brightness Adjustment: Keep pressing the power button and enter into the interface of contrast adjustment.
- Error Correction: Please prepare your own necessities and refer to the following procedure.
