Integrates more than 1,300 chip data models and more than 420 transistor data models, covering the most common general-purpose devices within 24 pins, which can greatly reduce maintenance workload and improve work efficiency. The cable is upgraded to FPC for better connectivity. Can test 74ch series, series, series, 4500 series, operational amplifiers, interface chips, optocouplers, transistor automatic detection and regulator voltage value detection. The maintenance assistant 9V laminated battery is the same as the standard multimeter battery, and its power consumption is very standard for a digital multimeter. Press the Enter key to turn on and automatically run the self-test. The self-test will detect the battery voltage and display it on the screen after more than two seconds. When the battery voltage is lower than 7V, please replace the battery to ensure measurement accuracy. If there is no alarm, you can start measuring. The original ad 10 ad, 5V voltage theoretical resolution is 0.0048V. Because it is battery-powered, it is not suitable for measuring high-power thyristors. The Zener value must be based on actual measurement, not just the nominal value. The default directory is initialized to the search directory. A standard optocoupler can test up to a dozen parameters. Measuring the logic ratio of the optocoupler alone has little practical significance. This machine can test the secondary saturation voltage drop of the optocoupler for reference. Test standard 4-pin optoisolator. M Multi-function IC tester Description: TSH series multi-function IC tester is a professional instrument designed by first-class microelectronics engineers and service personnel. You can choose different test modes: 5V/3.3V/automatic mode Note: Teaching: The panel has seven buttons: up, down, left, right, type key and hot keys O, P. The up and down keys are used to adjust the list and change the model, and the left and right keys are used to move the cursor left and right to select the item to be changed. The Enter key is used to turn on and off the machine and execute test commands. Open the 25#1.5V battery cover, then cover the battery cover, press and hold the Enter key for more than 2 seconds, and the device will turn on. The current battery voltage is automatically displayed when the device is powered on. The battery should be replaced when the battery voltage is too low. The low voltage affects the reliability of the test results and the automatic shutdown protection function. Power on: Press and hold the Enter key for more than 2 seconds to turn on. Shutdown: 1. Press the Enter key in the Off directory to shut down immediately. 2. Press to enter any directory and hold down the Enter key for more than 10 seconds to hang up. 3. Automatically shut down after 60 seconds of no operation. Fast: 1 Press the 0 key for quick shutdown (06 type) 2 P key for repeated self-test and reset Note: The appearance, color, and printed characters of different batches of products may vary, which does not affect the use Material: Plastic Color: As shown in the picture Note: Light reflection and different monitors may cause the product in the picture to be slightly different from the actual product color. The allowable measurement error is +/- 1-3 cm.
