Features:
Digital 1.8" LCD display for easy readings, which can display measured data clearly.
The processor adopts high-performance single-chip microcomputer ATmega328 and adopts external 8MHz crystal oscillator as the system clock.
Single button operation, supporting automatic shutdown for reducing power consumption.
Support the battery power, and the shutdown current is less than 20mA.
Each measurement time is about 2S, and only when measuring capacitance or inductance, the measurement time is longer.
Automatic detection of NPN and PNP transistors, N channel, P channel MOSFET AND JFET, diode, Dual diode, P-IGPT, Thyristor, Dual thyristor and so on.
For some thyristors and dual thyristors, when the transistor fails to meet the requirements of its triggering current and holding current, it is unable to use. For some IGPT with drive voltages over 5V, the transistor tester is not able to test them.
Support the identification of the pins of the test element.
Support the measurement of current amplification factor and base emitter turn-on voltage of bipolar transistors.
Through break-over voltage and current amplification factor, the Darlington transistor can be distinguished.
Support for test gate threshold voltage of MOSFET, Grid capacitance. Support simultaneous measurement of two resistors, and the data is displayed in a four bit decimal format.
Support potentiometer testing, but when the potentiometer is adjusted to one end, the intermediate pin and the terminal pin cannot be solved at this time.
A capacitor can be measured, capacitance range is 25pf-100mF and resolution is 1pF.
Capacitance less than 25pF measurements can be can be made by paralleling another known capacitance greater than or equal to 25pF, and subtracting the known capacitance from the result to obtain the measured capacitance.
When testing capacitance is greater than 90nF, its series equivalent resistance is also displayed, and the resolution is 0.01 ohms.
When testing capacitance is greater than 5000nF, the voltage loss after the test pulse can be measured, and this parameter can estimate the quality factor of the capacitor.
Support simultaneous measurements of two diodes, displaying the voltage drop of diode.
The light emitting diode is identified as a diode, and the test voltage drop is much larger than that of an ordinary diode. The two-color diode is identified as two diodes.
The resistance is less than 2100 ohms and its equivalent inductance is simultaneously measured, the range is 0.01mH-20H, but the measurement accuracy is not very good.
Program with self-test function to support multi parameter calibration.
Support frequency generator function, output by TP2, the output frequency range is 1Hz to 2MHz.
Supports a fixed frequency signal output from the TP2, the duty cycle can be adjusted by pressing the button.
Interface:
* J1: 2.54-2PIN, Used to input 7-12V voltage;
* S1: Red button, Reset button;
* S2: Green button, Operation button, Used for one button operation of the entire circuit board.
Attention:
1. Before testing capacitor, please be sure to discharge the capacitor.
2. When testing components that are welded to a circuit board, please be sure to disconnect the power from the circuit board, and the residual voltage is not allowed on the test equipment.
