Alarm Status; The Zero And Span Functions - Teledyne 2000RS Operating Instructions Manual

Operation

4.7.6 Alarm Status

The Alarm Status is non editable option. It is used to view the
status of whether a concentration alarm is active or not.
1. When alarm is active (alarm triggered), it will show "Reset
Alarm 1" or "Reset Alarm 2". If the alarm is inactive, it will
not show the Reset Alarm touch button.
2. Reset: Touch the Alarm Indicator icon on the Main screen to
reset the active alarm.

4.8 The Zero and Span Functions

Note: Zeroing is not required to achieve the published accuracy
specification of this unit.
Zeroing will eliminate offset error contributed by sensor,
electronics, and internal and external sampling system and
improve performance beyond published specification limits.
The analyzer is calibrated using zero and span gases.
Suitable gases for zero and span depend on the application
programmed in the 2000RS. Consult the sales order or separate sheet
describing factory calibration. If it is not clear, contact factory and supply
the serial number of the analyzer.
1. The Model 2000RS can have as many as three analysis ranges
plus a special calibration range (Cal Range); and the analysis
ranges, if more than one, may be programmed for separate or
identical gas applications.
2. If all ranges are for the same application, then you will not need
the Cal Range. Calibrating any one of the ranges will
automatically calibrate the others if all ranges are linear. If non-
linear, zero calibration is the same for all ranges, but span gas
must be done independently for each range.
3. If: a) each range is programmed for a different gas application,
b) your sensor calibration has drifted less than 10 %, and c)
your Cal Range was calibrated along with your other ranges
when last calibrated, then you can use the Cal Range to calibrate
all applications ranges at once.
If your Model 2000RS analyzer fits the paragraph (3) description, above,
