Page 52: Error Display
Error Display If the limits of allowed flow parameters are exceeded during a backpressure compensated measurement, an error message will be displayed. This can happen if there are flow reversals during the measurement or other changes in the flow during the measurement (such as changing a damper position), or as a result of other operator errors. -
Page 54: Chapter 7. Maintenance And Troubleshooting
Chapter 7. Maintenance and Troubleshooting The Model 8710 Micromanometer is designed for long-term field use. If used with reasonable care, it should be able to make precise measurements over a long time period. Some of the components can be cleaned periodically. When cleaning the components, please follow the instructions given below. Fabric Hood The hoods can be washed with mild detergent and cold water. -
Page 55: Cases
Cases If the instrument case or storage case needs cleaning, wipe it off with a soft cloth and isopropyl alcohol or a mild detergent. Calibration TSI recommends an annual calibration for the instrument. For a nominal fee, we will calibrate the unit and return it to you with a certificate of calibration and NIST traceability. -

Page 60: Appendix A. Back Pressure
Appendix A. Back Pressure The quantity of air flowing through a supply diffuser or a return grille is reduced to some extent whenever a capture hood is placed over the flow opening. The amount of flow reduction will vary depending on the combined effects of the diffuser/grille resistance, the capture hood resistance, and the flow rate. -
Page 62: Appendix B. Actual Vs. Standard Air Velocity And Flow Measurements
Appendix B. Actual vs. Standard Air Velocity and Flow Measurements Actual Air Velocity is also known as the “local” air velocity. It can be thought of as the speed of a microscopic dust particle being carried along in the air stream. Actual Air Velocity is measured with a Pitot tube using the basic formula: ×... - Page 63 Thus, to convert from Actual Velocity to Standard Velocity, use the following equation: ρ × Eq. (5) ρ Substituting known values into Eq. (5), we get: × × × × Eq (6) where: P is the local atmospheric pressure, as measured by the micromanometer, for example, in units of (in.
