RKI Instruments GX-2001 Data Logging with Calibration Station - Manual (Page 34)

34 • Viewing, Printing, Exporting, and Deleting Data
The fields also include the following:
• Gas — Lists the target gas for which the Before, After, and
A.Cal readings are displayed.
• Before — shows the settings prior to calibration.
• After — shows the settings after calibration.
• A. Cal. — lists the auto-calibration setting for each channel of
a Model GX-2001 unit. If a unit passes its calibration, the
“After” column should match the “A. Cal.” column. If the unit
fails calibration on any of its channels, those channels will
retain the previous calibration information.
NOTE: If a unit is calibrated using the Single Calibration menu
in the GX-2001 (see the GX-2001 instruction manual) it
is possible for the “After” reading to be different from the
“A.Cal” setting if the unit was set to a level different than
the “A.Cal” setting.
