The device evaluates the condition of the sensors during Calibration.
As the end of a sensor's life approaches, a warning is provided. While the sensor is still
fully functional, the warning gives the user time to plan for a replacement sensor to
minimize downtime. The Sensor Life indicator ♥ displays during ongoing operations as a
reminder of a sensor's pending end of life.
When a sensor's end-of-life is reached, sensor calibration will not be successful, and the
user is then alerted by a Sensor Life Alarm. A flashing Sensor Life indicator ♥ displays
during ongoing operations until the sensor is replaced and/or successfully calibrated.
Monochrome display - the Sensor Life indicator appears on the display at the same
position as the MotionAlert indicator. If MotionAlert is enabled (the + indicator displays)
and a Sensor Life warning or alarm occurs, the Sensor Life indicator ♥ takes priority and
is shown instead.
Color display - each displayed gas will have its own Sensor Life indicator. If a sensor is in
end-of-life warning, its indicator will be an orange ♥. If a sensor has reached end-of-life, it
is in alarm and its Sensor Life indicator will be a continuous blinking red ♥.
See 4.10 Calibration for additional details on Sensor Life determination and indication.
The backlight automatically activates when any front panel button is pressed and
remains ON for the duration of user-selected timeout.
This duration can be changed using the SETUP -
