FAQ
Q1: Why no temperature signal detected during heating?
A: Check if the temperature signal cable is properly inserted into the oil cup temperature hole.
Q2: How to handle abnormal empty cup capacitance or tanδ?
A: Re-clean the oil cup as standard procedure; check signal line connection and RF connector.
Q3: What is the standard empty cup reference value?
A: Capacitance 60pF±5pF, tanδ ≤0.00010; unqualified means need re-cleaning.
Q4: How to properly clean the electrode cup for precision test?
A: Use petroleum ether, acetone, neutral detergent and distilled water for step cleaning, oven dry at 105~110℃ for ≥1 hour, assemble with silk gloves.
Q5: The instrument does not heat up, what to check?
A: Check if the heating fuse is blown; confirm no abnormality in the induction heating module.
