SYSTEM/Parameters
O2 Slope - O
2
slope is data regarding the strength of the sensing cell output.
This information is automatically calculated after a calibration, and the user
does not normally input this data.
O2 Constant - O
2
constant is the amount of voltage a cell generates with
ambient air as the calibration gas. Again, this is normally calculated as a
result of calibration, and is not normally input by the user.
O2 T90 Time - Some users may feel that the O
2
reading is too active for
certain processes. This feature permits the user to dampen the O
2
signal. The
default value is zero seconds dampening.
Auto Tune - The electronics detects the line voltage powering the instrument
automatically, and picks proper algorithms for heater control. User can force a
high voltage algorithm, or a low, but Auto Tune is the default, and is
recommended.
Lockout Time - Keypad lockout time default is 30 sec., but it is user
configurable. A "Z" keypad pattern will unlock the keypad.
Revert Time - Once a user goes one level deep into the menu structure, an
additional "revert time" is provided to prevent nuisance lockouts. One hour is
the default, and it is user configurable.
Luminance - Gas fluorescence brightness is user adjustable.
SYSTEM/Status
Alarms - Diagnostic alarms. Section 8: Troubleshooting.
PID Parameter - Displays the line voltage, powering the Oxymitter, and infers
the temperature control algorithm being used to control heater temperature.
Reset Device - Device can be reset here as opposed to re-powering.
Calibration parameters will be lost.
SYSTEM/Software
This is data regarding the Oxymitter 4000 software version, and errors that
may have occurred.
SENSOR DATA
Displays information about the O
2
cell and thermocouple.
