Common Issues & Troubleshooting Steps

1. Tester Not Powering On

Symptoms:

• No LED indicators when connected to power.
• The device remains unresponsive after pressing the power button.

Possible Causes: ✔ Faulty Power Supply – The tester requires a stable 5V input; an incompatible or damaged adapter can prevent startup. ✔ Loose Connections – Poor contact between the power cable and the tester’s input port. ✔ Internal Circuit Issue – Rare but possible if the device has suffered physical damage.

Solutions:

1. Verify the Power Adapter – Ensure you’re using the original 5V power supply included with the tester. Test the adapter with another device to confirm functionality.
2. Check Cable Connections – Replug the power cable firmly into both the tester and the outlet. Try a different USB-C cable if available.
3. Inspect for Physical Damage – Look for signs of burns, bent pins, or liquid damage inside the power port. If found, professional repair may be necessary.

2. Inconsistent or False Test Results

Symptoms:

• A known-good chip fails the test.
• Test results vary unpredictably between repeated tests on the same chip.

Possible Causes: ✔ Poor Chip Contact – Dust, oxidation, or misalignment on the test socket can disrupt signal integrity. ✔ Power Fluctuations – Unstable voltage input may cause erratic readings. ✔ Outdated Firmware – Older versions might have bugs affecting accuracy.

Solutions:

1. Clean the Test Socket – Use a soft brush or compressed air to remove debris from the chip contacts. For oxidized pins, apply a small amount of isopropyl alcohol.
2. Ensure Proper Chip Insertion – Align the chip correctly in the socket, applying gentle pressure to guarantee full contact.
3. Stabilize Power Input – Connect the tester to a regulated power source or UPS to avoid voltage drops.
4. Update Firmware – Check the manufacturer’s website for firmware updates that improve testing algorithms.

3. Tester Detects All Chips as Faulty

Symptoms:

• Every tested chip is reported as defective, even when known to be functional.

Possible Causes: ✔ Incorrect Test Mode Selected – Different BM1368 variants (PB, AA, PA, PV) require specific testing protocols. ✔ Calibration Drift – Over time, the tester’s internal calibration may shift, requiring adjustment. ✔ Damaged Test Socket – Worn-out connectors can cause false negatives.

Solutions:

1. Confirm Chip Variant Selection – Double-check that the correct BM1368 model (e.g., PB vs. PV) is selected in the tester’s settings.
2. Perform a Calibration Test – Some testers include a self-calibration feature; refer to the user manual for instructions.
3. Test with a Known-Good Chip – Use a brand-new or verified working chip to rule out batch-wide defects.
4. Contact Support if Issues Persist – If recalibration doesn’t help, the tester may need servicing.

4. Intermittent Connectivity Issues

Symptoms:

• The tester disconnects randomly during operation.
• Data transmission errors occur mid-test.

Possible Causes: ✔ Loose USB/Data Cable – A worn-out or poorly connected cable can interrupt communication. ✔ Driver/Software Conflicts – Outdated or corrupted drivers may cause instability. ✔ Electromagnetic Interference (EMI) – High-power mining equipment nearby can disrupt signals.

Solutions:

1. Replace the USB Cable – Use a high-quality, shielded cable to minimize interference.
2. Reinstall Drivers – Download the latest drivers from the manufacturer’s website.
3. Relocate the Tester Away from High-Power Devices – Keep it at least a few feet away from miners or transformers.

5. Overheating During Prolonged Use

Symptoms:

• The tester becomes excessively hot after extended testing sessions.
• Performance degrades or tests take longer to complete.

Possible Causes: ✔ Insufficient Ventilation – Blocked airflow around the tester can cause heat buildup. ✔ High Ambient Temperature – Mining facilities often run hot, exacerbating thermal stress.

Solutions:

1. Allow Cooling Breaks – Let the tester rest for 10-15 minutes after continuous use.
2. Improve Airflow – Position the tester near a fan or in a cooler section of the facility.
3. Avoid Direct Sunlight – Keep the device away from heat sources like direct sunlight or miner exhaust vents.

Preventive Maintenance Tips

To minimize future issues, follow these best practices:

• Regularly Clean the Test Socket – Prevents dust buildup that can interfere with chip contact.
• Use a Surge Protector – Protects against power spikes that could damage the tester.
• Store in a Dry, Cool Place – Humidity and heat can degrade electronic components over time.
• Keep Firmware Updated – Ensures compatibility with new chip batches and bug fixes.
