TC-T7-H LCR-T7 LCR-TC1 Transistor Tester Multimeter lcr Meter For Diode Triode MOS/PNP/NPN Capacitor Resistor Transistor LCD TC-T7-H 1Overview 1.1Introduction 1-128x128 TFT display -Multi function key - Transistor test area -Zener Diode test area -IR receiver window -Micro USB Charging Interface -Charge indicator LED 1.2Features TC-T7-H is a TFT graphic display Multifunction Tester. lTransistor 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 lIR decoder -Support Hitachi IR coding -IR waveform display -Infrared receiving instruction lOther -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 Warning: Built-in Li-ion Battery, it is strictly prohibited the tester immersed in water, or near a heat source! Warning: For your personal safety, please strictly comply with the use of Li-ion Battery specifications and precautions! 2. Operating Instructions 2.1Key operational definitions Multi-function key has two actions: lShort pre: Pre the key and not le than 10 ms, release key within 1.5 second lLong pre: Pre the key more than 1.5 second 2.2Power on In the power off state, short pre the multifunction key, the tester is turned on and automatically measured. lPower on &measurement interface 2.3Detect transistor In the power off state or the test is completed, put the test element into the transistor test area of test seat, and pre the locking handle, short pre the multifunction key, the tester automatically measure, graphical display of measurement results when testing is complete. Warning: Always be sure toDISCHARGEcapacitors before connecting them to the tester! The tester may be damaged before you have switched it on! Warning: We do not recommend using the tester to measure the battery! The battery voltage must be le than 4.5V, otherwise the tester may be damaged! lComponent placement Test seat are p> lNo, unknown, or damaged part lBattery lBJT(Bipolar Junction Transistor) lDiode l2 Diode lMOSFET lThyristor lTriac lCapacitor lResistor lInductor 2.4Selftest Short all three Probes, short pre the multifunction key, the tester will be automatically calibrates itself. In addition to the calibration proce when prompted disconnect external wiring short(Isolate the probes), without the need for other operations. lCalibrating lIsolate the probe lSelftest End Warning: Do not carry out other operations in the calibration proce, so as not to affect the calibration accuracy! 2.5Detect Zener diode In the power off state or the detection is completed, put the Zener diode into the Zener diode test area of test seat, and pre the locking handle, short pre the multifunction key, the tester automatically measure, graphical display of measurement results when testing is complete. Warning: Do not put the component intotransistortest area, otherwise it is impoible to test zener diode! 2.6IR decoder After the component detection is completed, the infrared remote control at the tester "IR" test hole, pre the remote control key, the tester will be display the user code &data code and the corresponding infrared waveform after the succeful decoding. If decoding failure, the tester cannot display the user code and data code. The dot at the top right corner to indicate whether it has received the remote control infrared data, red represents infrared data is being received, blue represents decoding succe. Information:The IR decoder only support Hitachi IR format. 2.7Power off The Multifunction Tester with automatic shutdown and manual shutdown. lAutomatic shutdown When the component detection completed or IR decoding completed and after reaching the automatically shut down time, the tester automatically shut down. Automatic shutdown time can be set by the hardware jumpers, timeout support for 10s, 15s, 20s and 25s. Factory set to 20s. Warning: Adjust the automatic shutdown time required to open the housing, and use an electric soldering iron solder the jumpers. Attention:Please do ESD protection! lManual shutdown Long pre the multifunction key to force a shutdown in any state, while the measuring element is included. 2.8Built-in Li-ion Battery voltage measurement The built-in Li-ion Battery voltage is measured before detection, when the battery voltage is le than 3.0V will force shutdown, then please charging. 2.9Charging the Battery The tester has a
