Quarterly audits should be simple … thorough … but still as simple as possible. Unlike the Teledyne procedure (see below), our method is fully compliant with EPA Method 203, EPA Procedure 3, ASTM D 6216-98, and 40 CFR part 60.
This is a snippet of RIGAS’ procedure:
[1] record the serial numbers
[2] challenge the PLCF
[3] note the Fault indicators
[4] record current readings (including Dust Compensation)
[5] record current calibration values
[6] record calibration set points
[7] record LED drive current
[8] check purge air system (replace air filters as necessary [be careful not to disturb the dust, that will alter your EPA data])
[9] align
[10] perform a dust accumulation test (which cleans the optical surfaces as a PM measure)
[11] manual calibration cycle check
[12] record new Dust Compensation value
[13] install Cal Kit Fixture
[14] do NOT perform Background Set
[15] do NOT perform Normal Set
[16] do NOT remove Cal Kit Fixture
[17] do NOT perform Zero Set
[18] check Cal Zero value
[19] do NOT manual calibration cycle check
[20] analog output check
[21] perform Calibration Error Test
[22] record all EPA data from the data historian (or chart recorder)
[23] clean the unit (outside)
[24] complete the EPA compliant report
