2. Standard and supporting device<\/strong><\/h2>\n
\n
\n
– Standard Flow Meter ALICAT PCU, flow range up to 200L\/min or equivalent
\n– Connecting tube with various size, fitting with in\/out port of Unit Under Test (UUT) and standard meter (STD).
\n– Air flow generator range up to 200L\/min or more, with flow regulator or control valve.<\/div>\n

3. Environment conditions<\/strong><\/h2>\n
\n
\n
\n

– Temperature: (20 \u00f7 25)oC<\/p>\n

– Relative Humidity: (20 \u00f7 65)%RH<\/p>\n

\n
\n
\n

Note: environment conditions above apply for Techmaster inhouse laboratories. Outside this bound conditions will be considered with customer for uncertainty and measurement results.<\/em><\/p>\n

4. Preparation<\/strong><\/h2>\n
\n
\n
– Select suitable tubes, connect Air Flow Generator \u2013 STD meter and UUT, at the suction side or arrow direction\u00a0of each equipment.
\n– If UUT has control \/ adjustable valve, then connect UUT between Generator and STD meter.
\n– If UUT has internal pump, then Generator shall not be used. Connect UUT to STD meter directly.
\n– Teflon, quick-connector can be used if need.
\n– Ensure that system is no leak.
\n– Connect Air Flow Generator, STD meter, UUT to suitable power.
\n– Turn all on, allow warm up at least 30minutes or follow manufacturer\u2019s instruction.<\/div>\n
