9.2.3. PERFORMING A BASIC MANUAL CALIBRATION
The following section describes the basic method for manually calibrating the
T802.
If the analyzer’s reporting range is set for the DUAL or AUTO range modes, a
step will appear for selecting which range is to be calibrated: RNG1 (LOW) or
RNG2 (HIGH).
Each of these two ranges MUST be calibrated separately.
9.2.3.1. SETTING THE EXPECTED SPAN GAS CONCENTRATION
Note When setting expected concentration values, consider impurities in your
span gas.
The expected O2 span gas concentration should be 80% of the reporting range of
the instrument (see Section 5.4.1)
The default factory setting is 20.95 %. To set the span gas concentration, press:
Note For this Initial Calibration it is important to independently verify the PRECISE
Concentration Value of the SPAN gas. If the source of the Span Gas is from a
calibrated bottle, use the exact concentration value printed on the bottle.
