Buttons
When no buttons on the Analyzer are being pressed, the instrument is in the Analyze mode. It is monitoring the amount of oxygen in the sample gas that is flowing through the Remote Probe.
When one of the Function Buttons is being pressed, the Analyzer is in the Setup mode or the Calibration mode.
The 4 Setup Mode buttons on the analyzer are:
•SET HI ALARM
•SET LO ALARM
•SET HI RANGE
•SET LO RANGE
The Calibration Mode button is:
•SPAN
The Data Entry buttons (∆ and ∇) increment the values displayed on the TRACE OXYGEN meter while one of the Function buttons is being held down.
•∆ : Increments the displayed value upwards.
•∇ : Increments the displayed value downwards.
Any of the functions can be selected at any time by holding down the appropriate button.
Each function will be described in the following sections. Although the operator can use any function at any time, the order chosen in this manual is appropriate for an initial setup.
4.3Setting the Analysis Ranges
The two user definable analysis ranges are both capable of being adjusted for from
Whatever values are selected, the analyzer automatically switches from the LO range to the HI range when the oxygen concentration reaches the LO range fullscale value, and it switches back to the LO range when the oxygen concentration falls below the LO range fullscale value
Note: For proper operation, the HI Range setpoint should be set at a higher concentration than the LO Range setpoint.
