37、he operating value. The wattmeter currentconnection may be at its most sensitive position. Subtract thisloss value from the total load indication to obtain the true load.As an alternative method, use the following equation:WC5 WI2 V2/ RTwhere:WC= corrected wattage,WI= indicated wattage,V = voltmeter

Test Procedure8.1 Operate the vacuum cleaner motor/fan system with noorifice plate inserted in the plenum chamber inlet at nameplaterated voltage 61 % and fr
39、equency 61 Hz for 1 h prior to thestart of the first test run. For vacuum cleaner motor/fan systemswith dual nameplate voltage ratings, conduct testing at thehighest voltage.8.2 For each subsequent test run, allow the unit to reach itsnormal operating temperature by allowing the vacuum cleanermotor/
40、fan system to operate at the open orifice for 1 to 2 minbetween test runs.8.3 While operating the vacuum cleaner motor/fan systemper 8.2, insert orifice plates sequentially into the orifice plateholder of the plenum chamber starting with the largest sizeorifice and following it with the next smaller
41、 orifice plate. Usethe following orifice plates: 2.0, 1.5, 1.25, 1.0 0.875, 0.75,0.625, 0.5, 0.375, 0.25 and 0.0 in. (50.8, 38.1, 31.7, 25.4, 22.2,19.0, 15.8, 12.7, 9.5, 6.3 mm). The following optional orificeFIG. 2 Example of Standoff PipeFIG. 3 Mounting Plate and GasketFIG. 4 Schematic Diagram of
42、Meter ConnectionsF2105063plates may also be used: 2.5, 2.25, 1.75, 1.375, 1.125 in. (63.5,57.2, 44.5, 34.9, 28.6 mm).8.4 For each orifice plate, record the suction, h, and inputpower, P, in that order. All readings should be taken within 10s of the orifice insertion. Allow the vacuum cleaner motor/f
43、ansystem to operate at the open orifice for 1 to 2 min beforeinserting the next orifice.8.4.1 Read the suction to the nearest graduation of themanometer. Readings should be taken as soon as the manom-eter reaches a true peak. (When using a fluid type manometer,the liquid level may peak, drop, and pe
44、ak again. The secondpeak is the true peak reading. A person conducting the test forthe first time shall observe at least one run before recordingdata. See Specification F 431 for instructions on how tominimize the overshoot (first peak) of the liquid level.)9. Calculation9.1 Correction of Data to St
