Feature

●Can set the number of measurements before the power is automatically turned off, with one?key operation, automatically turn off the power.
●Use ATmega 8, ATmega 168 or ATmega 328 microcontrollers. 2x16 character LCD display shows the result.
●Automatic detection of PNP and NPN bipolar transistors, N and P channel MOSFETs, JFETs, diodes, double diodes, thyristor thyristors. Automatically detect the pin layout.
●Support automatic power off. ATmega168 with 1.05k version software uses sleep mode to reduce power consumption when there is no measurement.
●Built?in self?check function and optional 50Hz signal check the clock frequency accuracy and wait for calling (ATmega168).


Description

Feature:
1. Only one measurement is needed to find out the connection of the full bridge. The test time is about two seconds, only capacitance and inductance measurements will take a long time.
2. Support the measurement and symbol display of two resistances, up to four digits and unit display.

Specification:Item Type: Transistor Tester
Material: Aluminum alloy
Model: LCR-T4
Note:
1. All functions are only used for microcontrollers with more program memory, such as ATmega168. The resolution of resistance measurement is 0.1 ohms, and the highest measurement value is 50M ohms.
2. LED is detected as a diode, and the forward voltage drop is much higher than normal. The double light-emitting diode is detected as a double diode. It is possible to show signs of the correct direction for two diodes.
3. If the test current exceeds the holding current, SCR and triac can be detected. However, some semiconductor thyristors and triacs have higher trigger currents than the tester can provide. The available test current is only about 6mA!
4. Optional equipment calibration port output internal resistance and zero-offset self-test capability measurement (ATmega168). A 100nF to 20uF capacitor is required to connect between pin 1 and pin 3 to compensate the offset voltage of the analog comparator. This can reduce the measurement error of capacitors above 40uF. The internal correction voltage reference voltage with the same capacitor was found to adjust the gain of the internal reference measurement ADC.
