-FLOW CORRECTION EXAMPLE-
The balancer is consistently measuring a Total value of 9,500 CFM, which is 500 CFM less than the
10,000 CFM value on the MicroTrans
II
display (Total). The user would then perform the following
math function: Total Measured Value / Total Displayed Value = K-Factor so 9,500 CFM / 10,000 CFM
= 0.950. The user would enter 0.950 for the K-Factor Flow Correction. If the K-Factor Calculator is
used, the K- Factor Flow Correction would automatically update the K Factor.
8.6. AUTOZERO
The AutoZero option detects and corrects any zero offset caused by large ambient temperature changes.
