LED AND IC INTEGRATED CIRCUITS TESTER MODULE
This is a multifunctional tester. It is used to test many digital integrated circuits and some other analog ones. It features a small size and is easy to operate. Another advantage is that it works with a single battery
- Determine the model if it is within the list mentioned below.
- Verifies the operation of the chip in a few seconds.
- Uses one battery (AAA SIZE, 1.0 V to 1.5 V). Please work below 1.2V power supply current about 200mA, please do not press the test button without electricity.
- The test speed, approximately 0.5 s, to complete the test and start displaying the results.
- The results are shown on a 7-segment display
Usage method:
1. Connect the power supply. (Install the battery)
2. Put the chip to be tested into the IC test socket, the chip gap facing down, the top alignment, as shown in the figure below.
3. Press the test button (long press), if the chip is in good condition, the LED display will show the reference of the chip being tested after 0.5s.
4. If there is any damage to the chip, the chip is misplaced, or the chip is beyond the test scope, it will take about 0.5s for the LED display after the test button to display "ERR", but it will not will cause no damage to the chip to be tested.
Note:
1. Do not test online components.
2. Some will contain more than one type of IC test result, for example, to test the 74 hc139 it will show the CD4556 hc139 74, this is because the 74 hc139 and CD4556 have logic function and pin are the same. themselves. test button time will stay longer, all models show test release button completion again.
3. Do not test loaded components.
4. Do not insert foreign bodies into the blockage test block.
5. When the battery voltage is less than 1.0V, the display is abnormal, it may appear when the
battery needs to be replaced.
