Teledyne 9060L - Zirconium oxide flue gas oxygen analyzer - Manual (Page 13)

Percent Oxygen Analyzer Introduction
Teledyne Analytical Instruments 13
• Set Alarm 2 Sets the concentration at which alarm 2
activates upon dropping below the
threshold (LO alarm).
• Set HI Range Set the high analysis range for the
instrument (up to 0-100%).
• Set LO Range Set the low analysis range for the
instrument (down to 0-1%).
• Span Span calibrate the analyzer.
Data Entry Keys: Two pushbutton membrane switches are used to
manually change measurement parameters of the instrument as they are
displayed on the LED meter readout:
• Up Arrow Increment values of parameters upwards
as they are displayed on the LED readout.
• Down Arrow Increment values of parameters
downwards as they are displayed on the
LED readout.
Digital LED Readout: The digital display is a LED device that
produces large, bright, 7-segment numbers that are legible in any
lighting environment. It has two functions:
• Meter Readout As the meter readout, it displays the oxygen
concentration currently being measured.
• Measurement Parameters Readout The parameter readout
displays user-defined alarm setpoints, ranges, span calibration
point when they are being checked or changed, and probe
temperature on demand.
