(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. (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. (2) At the conclusion of the 24-hour period, the following hourly and daily values must meet the criteria in § 3175.141(d):

   1. (i) Volume;
   2. (ii) Integral value;
   3. (iii) Flow time;
   4. (iv) Average differential pressure;
   5. (v) Average static pressure; and
   6. (vi) Average flowing temperature.

(c) Other tests. The following additional tests must be performed on the flow-computer software:

1. (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. (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.
