Transistor Tester LCR-TC1 LCR-TC2 TCR-T7 TC-T7-H Color Display Multi-function Transistor Tester Capacitor Resistor Diode Triode

What's the difference between 4 versions?

LCR-T7 / LCR-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, and thyristors, it can also measure additional
  • voltage regulators, infrared decoding (limited for Hitachi(TM) format)

TC-T7-H: is an upgraded version of LCR-T7, the Up-to-date / fastest version

LCR-TC2:

  • is an upgraded version of TC-T7-H. Compared with TC-T7-H, it has upgraded
  • circuit structure, long-lasting battery life, optimized code, resistance
  • is one thousandth (this is related to repeated test consistency, that
  • is, the same resistance is not repeated test There will be changes, and
  • some repeated tests will have errors)

Warning: Built-in lithium-ion battery, it is strictly forbidden to immerse the tester in water or near a heat source!

Warning: For your personal safety, please strictly observe the specifications and precautions for using lithium-ion batteries!

Transistor Detection:

After the power-off state or test is completed, put the test component into the transistor test area of the test socket, press the lock handle, and press the multi-function key, the tester automatically measures, and the measurement result is displayed at the end of the test.

Warning: Always discharge the capacitor before connecting them to the tester! The tester may be damaged before you turn it on!

Warning:

We do not recommend using a tester to measure the battery! The battery voltage must be less than 4.5V, otherwise, the tester may be damaged!

Component placement:

The test socket is divided into transistor and Zener diode test areas, as described in 1.1.

Note: Do not perform other operations during the calibration process to avoid affecting the calibration accuracy!

Packing List:

  • 1 x multifunction TFT transistor tester
  • 1 x electronic component group (sent randomly)
  • 3 x test hook

Short the three test sockets press the multi-function button shortly, and the tester will automatically calibrate.

No other operations are required after disconnecting the short wiring according to the prompt during the calibration process.
