Tool/software:
Hi everyone,
I'm in the process of designing a test jig/test bench and would really appreciate your suggestions and guidance.
The main objectives are:
- Detect short circuits between two points and provide a clear indication (e.g., LED or buzzer).
- Check for continuity between two other points and indicate whether the connection is good or not.
- Send a signal to a controller (microcontroller or PLC) to log the result or trigger further action.
- Ensure the overall system is safe for both the operator and the device under test (DUT) — no risk of damage or incorrect readings.
I'm looking for input on the following:
- Reliable methods or circuit designs to detect shorts and verify continuity.
- Techniques to prevent false positives/negatives, especially in noisy environments or with varying load conditions.
- How best to interface the test jig with a controller for pass/fail status reporting.
- Any recommended components (op-amps, comparators, opto-isolators, etc.) or reference designs you've found effective.
If you’ve worked on a similar system or have insights into best practices, I’d really appreciate your advice!
Thanks in advance!
