FAQ

What type of thermocouple sensors does the instrument support?
The instrument supports K-type thermocouple sensors.

Can I use the instrument with sensors raised to voltages exceeding 24 V AC/DC?
No, to prevent any risk of deterioration to the thermometer, do not use it with sensors raised to voltages exceeding 24 V AC/DC as the sensors are electrically connected to the thermometer input.

What should I do if the thermometer is subjected to great variations in ambient temperature?
If the thermometer is subjected to great variations in ambient temperature, wait for 20 minutes after it becomes stable again before continuing with the measurement.
