The most accurate range of the gauge is the midrange, and the gauge should be calibrated to this area. 5 0 obj For additional details, refer to our Privacy Policy. Before operating, cool the volume meter to the approximate temperature of the beer being tested.

When the gauge pressure is steady, remove the aspirator bulb (1042) and partially open the top vent valve (1020-B) so that the pressure on the gauge drops about 1 psi. The pressure gauge has been calibrated to plus or minus psi (mid-range) and the thermometer tested to plus or minus degree prior to shipment of the instrument.
