As titled, how to replace the probe or clips of the Topdon CT100 circuit tester?
Here is the clue:
Yes. You can use your current probes or clips, or purchase compatible accessories from other brands. The tester only works with 4 mm connector accessories.
Note: Replacing the accessory may affect test accuracy.
Some other FAQs releated to the Topdon CT100 circuit tester:
Q: What should I do if the spring wire of the supplied clip is not long enough?
A: You can extend the cable by connecting an additional wire using an adapter.
Note: This may affect measurement accuracy.
Q: What should I do if the tester does not operate properly?
A: Check the voltage source and connections, then test again. If the tester still does not function correctly, contact customer service.
Q: Why is the light dim during the load test?
A: During the load test, the tester applies current based on the measured voltage (for example, 0.6 A at 12 V, 1 A at 24 V, and up to 1.2 A at 30 V). When the voltage is low, the applied current is reduced, and the built-in lamp dims. Therefore, a dim lamp indicates low circuit or battery voltage.
Q: Can the load test be used to determine whether a battery or circuit is weak?
A: You can make a basic judgment by observing the voltage drop during the load test. If the voltage drops by more than 3 V under load, the battery or circuit may be weak. For a more accurate assessment, use a dedicated battery tester to check battery health, charging status, and other parameters.
Q: Why does the screen repeatedly turn off and on and the buzzer beep during the load test?
A: This may occur when the current of the circuit or battery is below 0.4 A, which is insufficient to support the normal operation of the tester. As a result, the tester may repeatedly interrupt the test, causing the screen to turn off and on and the buzzer to beep. Try using another power supply or test tool for measurement.
