Optocoupler module online tester

Can be used with one hand, widely applicable
Dual signal lights are more convenient
Compatible with most 4-pin optocoupler online tests,
817, 781, 521 and other plug-in patches can be tested

2 versions available:
V5.0 Basic test functions, compact and easy to use, economical
V6.0 Upgraded version, equipped with rechargeable lithium battery, LED lighting



Spring-loaded probe, more flexible and stable contact



Two detection methods are supported:



How to use:
1. During the test, make sure that the board being tested is powered off and the large electrolytic capacitor on the motherboard has been fully discharged. It is strictly forbidden to test when the motherboard is powered on.
2. Confirm that the No. 1 pin of the optocoupler (the pin with a small dot) has the corresponding No. 1 pin mark on the test board
3. Connect the optocoupler test board to the USB power cable, and the probe of the test board touches the optocoupler to be tested. If the indicator light on the optocoupler test board keeps flashing, it means that the optocoupler is good (the brightness of the indicator light may be different, as long as it flashes, it means that the optocoupler is good)
4. During measurement, ensure that the optocoupler test board has good contact with the optocoupler being tested
5. If the indicator light is always on or off, remove the optocoupler from the circuit board and insert it into the optocoupler seat of the test board to confirm the test result again.
6. Applicable to 4-pin optocouplers, other types of optocouplers are not applicable for the time being.
