Error Possible causes Solutions


The operation interface cannot be connected or do not display measurement results


Controller and cable

connection error

Reconnect the

controller and cables

Cable failure Please contact us

The fluorescent cap is not

tightened or damaged

Reinstall and tighten the fluorescent cap or replace the fluorescent cap




The measured value is too high,

too low or the value is continuously unstable



The outer surface of the fluorescent cap is attached by foreign objects Clean the outer surface of the fluorescent cap and agitate the probe during measurement
Fluorescent cap is damaged Replace the fluorescent cap
The fluorescent cap has exceeded its service life  


Temperature measurement exceeds measurable range or garbled reading

Controller and cable connection error Reconnect controller and temperature sensor cable
Temperature sensor is attached to foreign objects Gently brush the attachment with a soft brush
