Oxymitter 4000
Instruction Manual
SYSTEM/Parameters
O2 Slope - O2 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 - O2 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 O2 reading is too active for certain processes. This feature permits the user to dampen the O2 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
SYSTEM/Software
This is data regarding the Oxymitter 4000 software version, and errors that may have occurred.
SENSOR DATA
Displays information about the O2 cell and thermocouple.
