Description
This is for the newer units, ones with the larger 8-line screen display.
The unit is designed to perform a calibration check and automatic zero procedure at pre-determined times to ensure accuracy.
During the annual service and calibration performed at an approved service center, all components are tested and adjusted to ensure that flow rates and sensors have the proper settings to allow this procedure to take place. As certain sensors age, the service center can adjust to bring those sensors back into the center of the calibration range, often extending their useful life and accuracy.
The full service will include a replacement O2 sensor, NO sensor, filter, batteries, and pump as required along with a filter pack and return shipping.
Excludes parts damaged due to physical damage or abuse as described in the Limited Express Warranty statement.
