1.1 Instructions

1.2 Function Introduction

TC-V2.12k is a multi-function tester using TFT graphic display.

Multi-function Tester（TC-V2.12k）

Content

2 Operating instructions

• Transistor tester

2.1 Key operation definition

2.2 Power on

There are two operations for multifunction keys

When the camera is turned off, press the multi-function button briefly, and the tester will turn on and measure automatically.

• Short press: Press the key not as short as 10 milliseconds and release the key in 1.5 seconds• Long press：Press the button for more than 1.5 seconds

• Power on & Measurement Interface

- Automatic measurement of NPN and PNP transistors、- N-channel and P-channel FETs, diodes (with dual diodes), resistors (with potentiometers), inductors, capacitors, thyristors,batteries (0.1-4.5V) and other components- Automatic test voltage stabilizing diode（0.01-30V）

- Automatic calibration function

• Infrared decoder

- Support Hitachi encoding- Infrared waveform display- Infrared receiving indication

Notice: Built-in lithium battery，It is forbidden to immerse the tester in water, and it is forbidden to approach the hot and high temperature source!

Notice: For your personal safety, please strictly observe the use of lithium battery standards and matters of attention!

• Others

- Measurement results using TFT graphic display- One-button operation- Automatic shutdown (shut down time can be set)- Built-in large capacity rechargeable lithium battery- Lithium battery voltage detection- Support Chinese and English bilingualism

2.3 Test transistor

When the shutdown or test is completed, the components to be tested are put into the test area of the test block, and press the locking handle, and press the multi-function button. The tester automatically performs the measurement. After the test is completed, the graphics show the measurement results.

• Placement of components The test seat is divided into the transistor test area and the voltage stabilizing diode test area, as detailed in the 1.1 machine instructions.• Non component, unidentified or component damage

• Battery （There are 6 forms:）

Notice: Be sure to discharge the component in front of the test seat so as not to damage the tester!

Notice: It is not recommended to use a tester to measure the battery! When measuring the battery, make sure that the voltage is less than 4.5V, or the tester will be damaged.

illustration: The following will no longer enumerate the various test methods of the components,explain only one of them.

• Triode

• Diode

• Double diode

The measurement result of the voltage regulator diode below 4.5V is also dual diode：

• Field effect tube

• Silicon-controlled

• Bidirectional triode thyristor

2.4 Automatic calibration

Potentiometer or two resistors：

Short connection of three test seats, short press multi function keys, the tester automatically calibrated.In the process of calibration, there is no need to do other operations except the short wiring is disconnected according to the prompt.

• Capacitor

• Inductor

• Start calibration

• Resistance One resistor：

2.5 Test zener diode

When the shutdown or test is completed, the voltage stabilizing diode is put into the test area of the voltage stabilizing diode, and the locking handle is pressed, and the multi-function button is pressed short. The tester starts and automatically measures, and the graphics show the measurement results after the test is completed.

• Break short connection

• Calibration end

Notice: Do not perform other operations during calibration so as not to affect calibration accuracy!

Notice: Do not put components in the component test area, or you can not test the voltage regulator diode!

2.6 Infrared decoding

2.7 Power off

After the component test is completed, the infrared remote controller is aligned to the "IR" test hole of the tester, press the remote control button, and the user code and data code are displayed after the tester is successfully decoded, and the corresponding infrared waveforms are displayed. If no decoding or decoding fails, the user code and data code can not be displayed. If the interface of the tester is not able to enter the infrared decoding interface, if the infrared decoding interface still displays the last successful decoding information. The upper right corner points are used to indicate whether the infrared data of the remote control is received. Red indicates that the infrared data is being received, and the blue indicates that the decoding is successful.

The multi-function tester has the function of timeout automatic shutdown and manual shutdown。

Press and hold the multi-function button in any state to forcibly shut down, including while measuring components.

When the component test is completed or the infrared decoding is completed and the automatic shutdown time is reached, the tester is automatically turned off. The auto-off time can be set by the hardware jumper, support 10 seconds, 15 seconds, 20 seconds and 25 seconds four-block timeout, the factory setting is 20 seconds.

• Automatic shutdown at timeout

• Manual shutdown

Notice: Adjust the automatic shutdown time to open the shell, and use the electric soldering iron to shorten the jump line.

Notice: Please do ESD static protection during welding!

illustration: The infrared decoder only supports Hitachi encoding format.

2.9 Built-in lithium battery charging

3 Performance parameters

Component type Rang Parameter description

The built-in lithium battery voltage will be detected before each component measurement and displayed. When the battery voltage is less than 3.0V, it will be forcibly shut down. Please charge at this time.

Multi-function tester can automatically identify components and pin arrangement, automatic range switching.

The main performance parameters are as follows：
