Page 3: Functional Description
® ® User Manual - PolyGard 2 / µGard Sensors for Toxic Gases Page 3 Intended Use The PolyGard 2 sensors (SC2) are designed for the measurement of toxic gases and oxygen in a wide range of applications only in connection with a basic unit, e.g. SB2, MSC2, MSB2 and WSB2 of the PolyGard series. -
Page 4: Installation
® ® User Manual - PolyGard 2 / µGard Sensors for Toxic Gases Page 4 2 Installation Electronics can be destroyed by electrostatic discharge (ESD). Therefore the installation work should be done only by persons connected to ground, e. g. by standing on a conductive floor or by taking appropriate grounding measures (acc. -
Page 5: Electrical Connection
® ® User Manual - PolyGard 2 / µGard Sensors for Toxic Gases Page 5 3 Electrical Connection 3.1 Plug Connection (SC2) in SB2, MSB2, MSC2, WSB2 SC2 sensors are equipped with a reverse polarity protected connector (3-pin). It must not be plugged in the wrong position by force (already clamped at the factory). -
Page 6: Calibration
® ® User Manual - PolyGard 2 / µGard Sensors for Toxic Gases Page 6 5 Calibration The service tool STL06 or PCE06 Software are available for convenient on-site calibration. See description of Service Tool STL06 or PCE06 Software. There is also the possibility to exchange the SC against a calibrated SC on site. The used SC can then be calibrated directly in the office or at the MSR_E Calibration Service and then reused again. -
