units of standard liters per hour. This standard flow rate is corrected to
1013.25 hPa (1 atm, 29.92 in Hg, or 760 mm Hg) and to the temperature
displayed next to NORM. The last line of this screen shows the pump
control voltage output in percent (%).
Attach the small sample tube adapter to the Model 5030 inlet. Attach the
inlet adapter to the sample tube. Depending upon your NIST-traceable
volumetric flow transfer standard (FTS), you may either attach your FTS
now or add the flow audit adapter to accommodate any flexible tubing that
your FTS may require. Allow 60 seconds to stabilize the flow.
Note Keep this inlet assembly for nephelometer zero.
Record the Model 5030 Volumetric Flow Rate as Qm and the FTS flow rate
as Qi, assuring that both are being recorded in units of L/h. Take three (3)
readings each from Qm and Qi and average the respective values. Use the
following equation to calculate the percent difference:
If %D is within ±4%, then the Model 5030 volumetric flow rate acceptance
test has passed. If the Model 5030 volumetric flow rate is slightly out of
tolerance, ±5%, the acceptance test should be classified as marginal. If the
volumetric flow rate performance is less than marginal, please contact
Thermo Fisher Scientific's Technical Support at (866) 282-0430 or your
local sales representative.
The Model 5030 Volumetric flow rate calibration is covered in the
"Calibration" chapter.
Perform a leak test. Refer to "Leak Test Procedure" on page 2-10.
Prior to field installation, the inline nephelometer should be tested and
zeroed. There are two approaches that can be used at this point:
•
Perform a background zero on the Model 5030 nephelometer (~2
minutes), or
