TC-T7-H TCR-T7 LCR-TC1 LCR-TC2 Transistor Tester Multimeter Colorful Display For Diode Triode MOS/PNP/NPN Capacitor Resistor Transistor What's the difference between 4 versions? T7 / TC1 Color screen / M644 chip, two functions are the same! T7 is slightly faster! The TC1 screen is slightly larger and they are all powered by lithium batteries. In addition to measuring resistance, capacitance, inductance, diodes, MOS transistors, thyristors, it can also measure additional voltage regulators, infrared decoding (limited to for Hitachi format) T7H It is an upgraded version of T7, Up-to-date / fastest version TC-T7-H 128x128 TFT display Multi function key Transistor test area Zener Diode test area IR receiver window Micro USB Charging Interface Charge indicator LED LCR-TC2 It is an upgraded version of TC-T7-H. Compared with TC-T7-H, the circuit structure is upgraded, the battery life is longer, the code is optimized, and the resistance is one-thousandth (this is related to the consistency of repeated tests, which is The same resistance repeated test will not change). 1.TC-T7-H (TFT graphic display Multifunction Tester) Transistor Tester: Automatic detection of NPN and PNP bipolar transistors, N-channel and P-channel MOSFETs, JFETs, diodes (including double diodes), N- and P-IGBTs, resistors (including potentiometers), inductors, capacitors, thyristors, triacs and battery (0.1-4.5V) Automatic detection of zener diode(0.01-20V) Self test with automatic calibration IR decoder: Support Hitachi IR coding IR waveform display Infrared receiving instruction Other: Measurement results using TFT graphic display(160x128) One key operation Auto Power Off(Timeout Settable) Built-in high capacity rechargeable Li-ion Battery Li-ion Battery voltage detection Support Chinese and English Performance Parameters: Multifunction Tester can automatically identify elements and automatic detection of pin layout, and automatic switching range. The main performance parameters are as follows: Component Range Parameter Description BJT - hFE(DC Current Gain), Ube(Base-Emitter Voltage), Ic(Collector Current), Iceo(Collector Cut-off Current (IB=0)), Ices(Collector short Current), Uf(Forward Voltage of protecting diode) Diode Forward Voltage
