"Basic operationCover the holes at the bottom of the orifice and pour in the liquid to be measured. Make sure that the viscosity flow cup is completely filled. Use the glass plate to scrape off any excess liquid from the edge of the flow cup. Uncover the holes at the bottom of the orifice. Negative pressure will keep the liquid in the cup until you're ready to begin measuring. Active a stopwatch (not included) while simultaneously removing the glass plate from the cup horizontally. As soon as the flow is interrupted for the first time, stop the watch and write down the time.Note: When using a viscosity flow cup, it is very important to make sure that the instrument is cleaned thoroughly after each measurement, as residue in the orifice and cup can jeopardize the accuracy of future measurements. Scratches also can cause inaccurate results.The PCE-127 series is available in two configurations: flow cup or immersion cup. The immersion cup features a handle intended for dipping into paint cans and other containers.
