Material Requirements
* Detcon PN 943-003270-000 MicroSafe™ Programming Magnet
* Detcon PN 943-000006-132 Calibration Adapter
* Zero Air gas containing no VOC compounds
* Span gas containing isobutylene in air. The cal gas concentration is recommended at 50% of range (which is the fac-
tory default) at a controlled f low rate of 200 cc/min. Example: for a Model PI-600 sensor with a range of 0-100ppm,
a test gas of 50 ppm isobutylene is recommended. For a sensor with a range of 0-10 ppm a test gas of 5 ppm is rec-
ommended, etc. Other concentrations can be used as long as they fall within 10% to 90% of range. See section
3.8.2 for details. Reference section 3.9-b-1 if you do not know the sensor target gas or range of detection.
3.8.1 Calibration Procedure - Zero
NOTE 1: Before performing a zero calibration, determine if there are any active VOC target gases in the area. If it can
be concluded that there are no active VOC gases in the area, then execute steps b) and c) below.
