TC1 T7 T7-H Transistor Tester Multimeter TFT LCD Display ESR Diode Triode Capacitance Resistor Meter NPN PNP MOSFET Multimeter

What’s the difference between 3 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:is an upgraded version of T7, Up-to-date / fastest version

LCR-TC1

Features:

It can be widely used to detect  NPN and PNP transistor, capacitor, resistor, diode, triode, N-channel and P-channel MOSFET, IGBT, JFET, triac and battery etc.

It can also be used to detect  infrared wave forms.

It also can detect  zener diode and has the function of  self-calibration.

After detection, align the infrared remote control with the “IR” light, then press the button in the remote control, if the detector successfully decode it, it will display the data code and infrared wave form.

One button operation, automatically detect and shutdown, and you can press the multi-functional button to close the detector too.

Put the pins of component in corresponding area, then dial the little handle and the detector will test it automatically, finally the results will display on the back light TFT screen clearly.

Not like the usual black and white display,  this detector will show results in color.
