(5) Precautions

1. The MF58 series thermistor is sealed with glass. Please do not subject it to severe shock or squeezing to prevent the glass tube from breaking.

2. Welding method: Use the method of direct welding between the metal body and the body. Do not use soldering to avoid welding, and the welding time should be controlled within 3.5 seconds.

3. Do not test the MF58 thermistor in the air. The temperature difference in the air is large and the measurement is very inaccurate. There will often be a deviation of more than 1-2°C. A high-precision constant-temperature oil tank must be used for measurement. The measured NTC discharge After entering the constant-temperature oil tank, the temperature of the constant-temperature tank must be stable before measurement.

4. The voltage should be as low as possible during measurement to reduce the measurement error caused by NTC self-heating.

5. When measuring high temperature, a thermometer needs to be used to correct and check the temperature of the thermostatic bath.
