LCR-TC1 1.8inch Colorful Display Multifunctional TFT Backlight Transistor Tester for Diode Triode Capacitor Resistor Transistor LCR ESR NPN PNP MOSFET
19 If more than three diode type parts inspection, failure to establish the number of diodes another message. This will only happen if the diode is connected to all three probes and at least one diode. In this case, you should only connect the two probes and start measuring again, one by one.
20 measures a single diode reverse capacitance values. Bipolar transistors also can measure, if you connect the base and collector or emitter.
21 need to find a measurement of the full-bridge connection.
25pf capacitor values lower than 22 are usually undetectable, but with a diode in parallel or at least 25pf capacitor in parallel. In this case, you have to subtract part shunt capacitance values.
23 ohm resistor will measure inductance of less than 2100, if you have at least 16K ATMEGA flash. Range from 0: 01mH than 20H, but the accuracy is not good. Measurement results show only a single connection element.
24 test time is about two seconds, only the capacitance and inductance measurements will take longer.
25 software can be set to automatically turn off the power to measure the number of times before.
26 built-in self-test function with selectable clock frequency of 50Hz signal check the accuracy and wait for the call (ATmega168 and ATmega328).
27 optional resistance and zero offset calibration of measuring equipment self-test capability of the port output (ATmega168 and ATmega328). Need a 100nF to 20uF capacitor connected to compensate the analog comparator between pins 1 and 3 of the offset voltage. This can reduce the measurement error 40uF above capacitor. With the same internal calibration capacitor voltage reference voltage is found to internal adjustment reference measurement ADC gain.
If the test current exceeds the holding current, the thyristor and triac can be detected. But some current higher than the semiconductor SCR and triac tester can provide the trigger current. Available test current is only about 6mA! Note that all functions have only used single-chip program memory as more ATmega168.
