5 PRODUCT MAINTENANCE 5.1 SCHEDULED MAINTENANCE Otis recommends that our equipment be calibrated a MINIMUM of every 90 days, and STRONGLY advise that calibration be performed every 30 days. Without knowing the specific application, sensor assembly location, gas exposure and other factors, the company recommends monthly calibrations – assuming no damage or potential damage has occurred to the sensor and that there has not been a power outage to the sensor assembly. -
Page 33: Sensor Replacement
The sensor elements used in the OI-6900 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. -
