5.1
Notice
This chapter discusses the user interfaces along with the Auto-Calibration Mode.
Types of Interfaces
User interfaces are provided so that the operator may interpret and direct the Model S800 in
the performance of its various functions. User interfaces consist of (Figure 3):
•
The
digital display
provides the user with the gas concentration at the sensor site,
fault diagnostic codes, and auto-calibration prompts.
•
The
status indicators
provide the user with an indication of the current mode of
operation (alarm, warn, fault, ready and calibration).
•
The Rest/Test and Calibration switches provide the user access to the LED/Ramp
test and auto-calibration functions.

Auto-Calibration Mode
To perform an auto-calibration, follow the procedure listed below.
•
Place the calibration cup from the
calibration kit (Use United Central calibration
kit #543568) over the sensor with splash guard in place and apply zero air.
•
Enter the Auto-Calibration mode by applying a magnet to the magnetic Calibration
switch (see Figure 10, sec. 7.2.1 for switch location) until the
CAL
LED lights (about
five seconds) then remove the magnet. The unit is now in the Auto-Calibration
Mode (Figure4).
