How long does it take to calibrate an air meter?
The required three-month interval is a good opportunity to give each meter a thorough cleaning and to check for damage and wear. Before you can perform the initial calibration of a Type B meter, you first must determine the volume of the calibration vessel against the capacity of the measuring bowl.
When to make an air fuel mixture adjustment?
Warm up the engine to normal operating temperature by letting it idle for about 5 minutes. Keep the engine running after it warms up. Always make air fuel mixture screw adjustments with a warm engine and the engine running, so you can listen to how the adjustments affect the engine’s idle speed.
How do you calibrate the AFX on a car?
The procedure to calibrate the AFX is as follows: 1. Connect the harness to the control module and the AFR sensor. With power disconnected from the harness and the sensor removed from the exhaust, hold the sensor by its wires letting it hang free in air.
Is there a correction factor for aggregates in the air meter?
Although a correction factor for aggregates is not part of the calibration process for the air meter, the ASTM/AASHTO test methods still require the determination. Air entrapped in aggregate particles doesn’t play a significant role in overall freeze/thaw durability of concrete, but if not accounted for, it can create misleading test results.
