GPR-2600 Series Oxygen Analyzer - Advanced Instruments Inc.

Advanced Instruments Inc.Auto Span:Manual Span:Timed Span Cal:Timed Span Cal in ___ days:Calibration will occur at ____:Timed Span Gas Value:Applicable only to analyzers equipped with an optional automated sample system. Thesystem automatically closes the sample inlet valve and opens the span inlet valve at apredetermined interval in time, see System Menu section above. It also trends thedownward slope of the oxygen reading vs. time curve. When the slope of the oxygenreading reaches “0”, the system initiates a SPAN CALIBRATION adjustment anddisplays an oxygen reading corresponding to the span gas value entered.The user must ascertain that the oxygen reading has reached a stable value, see SpanCalibration Adjustment above, before the system will accept and make a SPANCALIBRATION adjustment.Subtitle only, this function represented by the following menu options are applicableonly to analyzers equipped with an optional automated sample system.Requires the user to enter a “number” representing the interval in days before the nextSPAN CALIBRATION.Requires the user to enter a “military time in hours and minutes” representing the timeof day at which the next SPAN CALIBRATION will be initiated.Displays the numerical span gas value and units entered when the Auto Span optionwas initiated.Procedure – Zero CalibrationNote: Not necessary and thus not recommended for most percentage range measurements see Analysis Level Required sectionabove.The analyzer is online in the Auto Range mode as described above.Review the Analysis Level Required, Online Recovery Time, Zero Calibration Offset Adjustment and Menu Functions – ZeroCalibration above before proceeding.Assure there are no restrictions in vent line.Regulate the pressure between 5-30 psig and set the flow rate to 2 SCFH for Fuel Cell sensors.Allow the analyzer reading to stabilize below 50% of the most sensitive or lowest range available on the analyzer.Advance the cursor (*) to the “Zero” option as illustrated and press the green ENTER key to accept the selection.MAIN MENUSampleSpan* ZeroAlarmSystemStandbySample0.500 %Auto Range85⁰F 100Kpa0 to 1 %12/31/07 12:00:00The following menu appears:35
