SECTION 4 MICRO-TURN AUDIT KIT

USING THE ON LINE ZERO REFLECTOR (OPTION)

The "Micro-turn" 200 on - line test and audit system P/N 1232 may be used for:
▪
Opacity audit
▪
Linearity checks and adjustments
▪
System accuracy verification
▪
Service on line or off stack
The "Micro-turn" 200 on - line test and audit system P/N 1232 contains a test reflector, three
neutral density filters, filter certification certificates and carrying case. The Micro-turn 200
on-line test reflector is inserted over the transceiver lens.
FILTER CERTIFICATION
QA/QC testing by EMS of the filters at an interval of not more than 6 months is recommended. Filter certification, replacement or
additional Neutral Density Filters are available from EMS.
EMS Neutral Density Filters for Micro-turn 200 are calibrated on a Perkin-Elmer Lambda Series 6 / PECSS Spectrophotometer per
Federal Environmental Protection Agency specifications. These specifications are contained in the Code of Federal Regulations 40 CFR
60, Appendix B, Performance Specification 1, Attenuator Calibration. The filters are scanned over the visible region from 380 to 780
nanometers in one nanometer steps and the resulting transmittances of the filter are weighted to the Source C Human Eye Response
by multiplying each value by its associated response factor. The corrected values of transmittance are converted to % Opacity and the
value is recorded on the filter and associated chart.
