results is displayed below and is provided as a reference.
Use the following settings to adjust the meter calibration as it relates to your test results:
• Prover station mode. Use the drop-down menu to select the % in which your prover
station results are expressed:
◦ (Example selection) % Error
◦
% Accuracy

• Prover flow rate unit. From the drop-down menu, select the flow rate unit:
◦ (Example selection) Imperial (cubic feet per hour)
◦ Metric (cubic meters per hour)
• Prover flow rate check. Enter the prover station check flow rate. This is typically
20-35% of the meter capacity. (Example entry 50 CFH)
• Prover percentage check. Enter the value from the test mode screen for the meter's
check result. (Example entry +0.7).
• Prover flow rate open. Enter the prover station open flow rate. This is typically
80-100% of the capacity. (Example entry 250 CFH).
• Prover percentage open. Enter the value from the prover screen for the meter's open
result. (Example entry -0.3).
