What is the correct procedure for zero-point calibration of LGF electromagnetic flowmeter?

LGF electromagnetic flowmeter zero-point calibration is crucial for ensuring measurement accuracy. Before calibration, ensure the medium in pipeline is completely stationary with no flow, pipeline must be filled with measured medium without air bubbles.

Zero-point calibration procedure: First access calibration menu through Ecolor configuration software or field keypad, select zero-point calibration function. After system stabilization (typically 2-3 minutes), initiate zero-point calibration program. During calibration process, display shows calibration progress, system automatically saves calibration data upon completion.

After calibration completion, recommend recording calibration time and environmental conditions. Regular zero-point calibration helps eliminate temperature drift and electrode contamination effects, suggest performing zero-point calibration every 3-6 months or when measurement deviation is detected.
