Quick Troubleshooting for Temperature Profiler
1. Inaccurate temperature / Large deviation
Thermocouple type does not match instrument setting (K/J/T mismatch)
Poor contact, oxidation, or broken solder joint on thermocouple
Probe not tightly attached to product, measuring air instead
Instrument not calibrated for a long time
2. Erratic curve / Data dropouts
Damaged, shorted, or loose thermocouple wire
Loose connector, water or flux contamination
Damaged channel
3. Instrument fails to power on
Dead battery or poor contact
Water damage or moisture
4. Cannot start recording / No sampling
Start mode not set (temperature trigger / manual start)
Start temperature set too high
5. No data on PC / Cannot read data
Poor USB/data cable connection
Wrong instrument model selected in software
Data not fully recorded or ended abnormally
6. Instrument overheats / Damaged inside furnace
Damaged thermal barrier box
Placed near hot air or high-temperature area
7. Individual channel shows 0 / No change
Thermocouple open circuit
Damaged channel socket
