5.2 SENSOR REPLACEMENT
The sensor elements used in the OI-6000 detects gas in either % or PPM concentrations, this element must be fully
functional in order for the system to operate correctly. Otis recommends replacing the sensing element whenever a
slow response to gas is observed during the normal calibration process. After replacing the sensing element the
device MUST then be nulled and calibrated for proper operation of the device.
