Precautions Of The Enameled Wire NTC Thermistor 6.8k 3977
Welding method: The metal body and the body are directly welded for
welding. Please do not use tin soldering to avoid false welding.
The welding time is controlled within 3.5 seconds
Do not test the enameled wire thermistor in the air. The
temperature in the air varies greatly and the measurement is very
inaccurate. It often produces deviations above 1-2°C. It must be
measured with a high-precision constant temperature oil tank. The
tested NTC is placed in the constant temperature oil tank. After
that, the temperature of the constant temperature bath must be
stabilized.
