9.2.3. PERFORMING A BASIC MANUAL CALIBRATION
The following section describes the basic method for manually calibrating the
GFC7001T/GFC7001TM.
If the analyzer’s reporting range is set for the AUTO range mode, a step will appear for
selecting which range is to be calibrated (LOW or HIGH). Each of these two ranges
MUST be calibrated separately.
IMPORTANT
IMPACT ON READINGS OR DATA
If the ZERO or SPAN buttons are not displayed during zero or span
calibration, the measured concentration value during this time is out of
the range allowed for a reliable calibration. Refer to Section 11 for
troubleshooting tips.
9.2.3.1. SETTING THE EXPECTED SPAN GAS CONCENTRATION
Note When setting expected concentration values, consider impurities in your
span gas.
The expected CO span gas concentration should be 80% of the reporting range of the
instrument (see Section 5.4.1).
The default factory setting is 40 ppm. To set the span gas concentration, press:
