The Sensor Range is selectable between 0-20ppm, 0-50ppm, or 0-100ppm
depending on the installed sensor. To adjust the Sensor Range of the Model
S4000T, apply the magnet to the GM Logo on the cover of the unit until “SE” is
displayed, then remove the magnet. This puts the unit into Setup Mode. After a few
seconds “Sr” will be displayed. Apply and remove the magnet to adjust the Sensor
Range. The current Sensor Range will be displayed. To change the sensor range,
apply and remove the magnet repeatedly, until the desired range is displayed. Once
the desired range is displayed, wait 3 seconds and “Fi” will be displayed. Apply and
remove the magnet, to return to the next level of the Setup menu. When “Fi” is
displayed again, apply and remove the magnet to return to normal operation.
