Section 3175.142 - Required static tests(a)Instantaneous flow rate. The instantaneous flow rates must meet the criteria in § 3175.141(d) for each test identified in Table 1 to this section, using the gas compositions identified in Table 2 to this section, as prescribed in Table 1 to this section.

(b)Sums and averages.(1) Fixed input values from test 2 in Table 1 to this section must be applied for a period of at least 24 hours.(2) At the conclusion of the 24-hour period, the following hourly and daily values must meet the criteria in § 3175.141(d) : (iv) Average differential pressure;(v) Average static pressure; and(vi) Average flowing temperature.(c)Other tests. The following additional tests must be performed on the flow-computer software:(1) Each parameter of the configuration log must be changed to ensure the event log properly records the changes according to the variables listed in § 3175.104(c) ; and(2) Inputs simulating a 15 percent and 150 percent over-range of the differential and static-pressure transducer's calibrated span must be entered to verify that the over-range condition triggers an alarm or an entry in the event log.
