Description

1. Scope of application: can test 74ch series, osmo series, cd4000 series, hef400 series, 4500 series, operational amplifiers, interface chips, optocouplers, automatic transistor identification, voltage regulator voltage identification
2. Integrate more than 1,300 types of chip data models and more than 420 types of transistor data models, covering most common general-purpose devices within 24 pins, which can greatly reduce maintenance workload and improve work efficiency
3. Press the Enter key to turn on the machine for the first time and automatically run a self-test. The self-test detects the battery voltage and displays it on the screen after more than two seconds. When the battery voltage is lower than 7v, replace the battery to ensure the measurement accuracy. If If there is no alarm, the measurement work can be started
4. Nativead 10 ad, the theoretical resolution of 5v voltage is 0.0048v
5. Due to the use of batteries for power supply, it is not suitable for measuring high-power thyristors
6. The Zener value must be based on the actual measurement, not just the nominal value
7. The default directory for initialization is the search directory
8. Different test modes: 5v mode, 3.3v mode, auto mode
9. There are seven buttons on the panel, which are respectively used for up, down, left, right and typing keys and hotkeys o, p
10. The up and down keys are used to adjust the catalog 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
11. The input key is used to change the machine and execute the test command
12. Use two AA 1.5v batteries (not included), press Enter for more than 2 seconds to turn on the machine, and the current battery voltage will be displayed automatically when the machine is turned on. When the battery power is too low, replace the battery. Too low voltage will affect the reliability of the test results. and automatic shutdown protection
13. After 60 seconds without any operation, it will automatically shut down
14. Test socket: SOP16 narrow body, SOP20 medium body, SOP24 wide body

The device positioning method is as follows:
1. Place the chip and optocoupler on the top of the alignment, and the 1-pin ic alignment seat
2. The triode on the left, mostly three slots
3. The 13 and 14 pins of the ic regulator are placed
Note: Transistor display pin sequence from left to right corresponds to 10-foot, 11-foot, 12-foot ic block (not built-in battery or adapter)
