III Method of Balancing: Supply, Return and Exhaust diffusers, grilles and registers were measured with an Alnor Balometer EBT-721, which includes the flow hood, velgrid, pitot tube and airfoil. Heating and Chilled water flow rates were measured with an Alnor Hydronic Manometer HM-680 by obtaining pressure measurements. RPM was measured with a Shimpo tachometer. Amperage and Voltage readings were taken with a Fluke 930 meter. Instrumentation: Digital Manometer Alnor Balometer EBT-721 Flow hood Alnor Balometer EBT-721 Digital Pressure Gage Alnor Hydronic Manometer HM-680 Tachometer Shimpo Digital Volt-Amp Meter Fluke 930 Thermometer Alnor Balometer EBT-721 Warranty Information: This project was completed per TABB Procedural Standards. The data presented in this report is a record of system measurements and final adjustments that have been obtained in accordance with the current edition of the TABB Procedural Standards for testing, adjusting, and balancing environmental systems. Any variances from design quantities, which exceed TABB tolerances, are noted in the Test-Adjust- Balance Report Project Summary. If a Test-Adjust-Balance Report Project Summary is not issued directly following this cover page, all measurements met the design requirements as specified by the design mechanical engineer. This project has a one-year guarantee on all Testing, Adjusting & Balancing from the date listed on this cover page.
