## Description

Automatically identifies and tests a wide range of electronic components, transistors, MOSFETs, Zener diodes, resistors, capacitors and inductors, quickly displaying results in graphic and text format on the 160x128 TFT color screen. Powered by a rechargeable Li-ion battery via MicroUSB, it is easily controlled from a button, includes self-calibration, automatic detection and automatic shutdown for efficient work on the service bench.
LCR-T7 tester for automatic identification and testing of a wide range of electronic components, including PNP/NPN transistors, MOSFETs, Zener diodes, resistors, capacitors and inductors.
It is equipped with a 160x128 pixel TFT color screen, which displays measurement results in graphic and text form, providing clear and detailed information. It is powered by a rechargeable lithium-ion battery, with MicroUSB charging.
The tester is operated by using the multifunction button, the device is automatically turned off. It is equipped with self-calibration and automatic component detection functions.
Careful
Do not use the tester on live circuit boards. Do not measure charged capacitors! Do not insert multiple contacts into the socket at the same time. Avoid moisture and heat sources.

Use
1. Make sure all components are completely discharged, especially capacitors.
2. Do not test transformer coils or connect the device to live circuits.
3. Insert the component into the test socket and secure it with the locking lever.
4. Press the multifunction button to start testing.
5. Wait a few seconds until the results are displayed on the screen.
6. Recharge the device when the battery voltage drops below 3V, using a 5V USB source.
For self-calibration , short-circuit the first three sockets, press the multi-function button and remove the short-circuit from the first three sockets.
To decode IR signals, turn on the tester and point the remote control at the “IR” text marked on the front of the tester. The IR decoding function only supports Hitachi format.
Careful
Do not use the tester on live circuit boards. Do not measure charged capacitors! Do not insert multiple contacts into the socket at the same time. Avoid moisture and heat sources.
