Purpose of zeroing
Ensure accuracy: Regular zero calibration or zeroing can eliminate errors such as zero drift and ensure the accuracy and stability of the flowmeter. This is especially important for applications that require high-precision measurement.
Maintain equipment: Zeroing is also part of equipment maintenance. Regular zeroing can timely discover and solve potential equipment problems and extend the service life of the equipment.
Convenient for subsequent use: After the zeroing operation is completed, the flowmeter reading will return to the initial state, which is helpful for subsequent data recording and analysis.
Precautions
The zeroing operation should be performed after the flowmeter is working stably: to ensure the accuracy of the zeroing result.
Pay attention to the indicator light status and display value on the flowmeter panel: If there is any abnormality, the cause should be checked in time.
Ensure the stability of the gas source flow: During the zeroing operation, the gas source pressure should be avoided to be too high or too low, so as not to affect the accuracy and stability of the flowmeter.
