477B Manometer User Manual

The Popular New Dwyer Digital Manometer Series 477B is available with 0.1% full scale accuracy. The 477B contains a highly accurate differential pressure sensor that offers a 0.1% full scale accuracy on air ranges from 20" w.c. to 100 psid. Series 477B Handheld Digital Manometers are packed with features needed to make pressure measurements and recording faster, easier and more accurate than ever. Instantly select from up to nine of the most widely used pressure units without having to waste time and risk mistakes with tedious conversions. A non-volatile memory function enables storage of up to 40 readings - perfect for HVAC technicians making Pitot tube traverses of air flow readings across a duct. The 477B is also ideal for maintenance personnel or technicians that require a highly accurate standard to check their instrumentation or equipment to ensure proper performance.

When working in poorly lighted areas, just switch on the handy backlight feature. The manometer automatically shuts itself off after 20 minutes to minimize battery drain. Electronic zeroing means you simply touch a single key to perfectly null out any minor pressure differences. A display HOLD key freezes the current pressure for those all-too-common situations where readings fluctuate. Included is an audible alarm to warn of overpressure plus a visual alarm warning in case ambient noise levels are too high to hear the alarm. Audible alarm also confirms a value has been stored, eliminating the need to observe display during a duct traverse.

Clear, concise operating instructions for all functions are printed on the rear of the rugged extruded aluminum case for quick reference. One-piece front membrane fully protects all keys from dust and moisture; wipes clean in seconds. Detailed written instructions, a wrist strap and 9 volt alkaline battery are included.

477AV Manometer User Manual

The Dwyer 477AVHandheld Digital Manometer is available with pressure, flow, and velocitymeasurements along with a number of other features. The 477AV uses a highly accuratedifferential pressure sensor to offer ± 0.5% full scale accuracy. It displays negative,positive, and differential pressure. For pressure, flow, and velocity there areselectable English and metric units, as seen in the model chart below. Thebuilt-in air velocity and volumetric flow calculations conserve time associatedwith cumbersome manual calculations. Up to 40 readings can be saved—perfect forHVAC techs making traverse airflow readings across a duct with a pitot tube.The accuracy of the 477AV Series is essential for maintenance personnel andtechnicians who require a highly accurate standard to check theirinstrumentation or equipment against.

Thedigital display is back-lighted for easy viewing in dark areas. Battery conservation is monitored anddisplayed in the event of low battery condition. The digital manometer shutsoff automatically after 20 minutes. The shut-off time can be reduced ordisabled if necessary. The Series 477AV can be field-calibrated by setting zero& span values. The damping feature compensates for the fluctuating readingsby averaging input values to display a more stable readout. The unit features anaudible and visual alarm to warn over flow, over pressure or over velocity.

Displaying Pressure, Velocity, and Flow

The instrumentmeasures pressure using a piezoelectric sensor. When the 477AV is powered onthe pressure value and the unit of measurement will be shown. If you select thevelocity or flow mode, then velocity or flow will be displayed instead. Themode selection will persist even after the instrument is turned off. Invelocity and flow modes, if the reading exceeds 9,999, then a “K” will bedisplayed next to the unit of measurement and the display will read in units of1,000 times the original unit of measurement.
