RKI Instruments GX-2009 Data Logger Management Program - Manual (Page 74)

74 • Viewing, Printing, and Deleting Data in the Last Calibration Window
The fields on this screen include SerialNo, UserID, and
StationID just as in the Need Calibration/Need Bump Test and
Calibration Date/Bump Test Date screens. The Calibration
Record 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 the GX-2009. If a GX-2009 passes its calibration, the
“After” column should match the “A. Cal.” column. If the
GX-2009 fails calibration on any of its channels, those
channels will retain the previous calibration information.
NOTE: If a unit is calibrated using One Cal in the GX-2009’s
Calibration Mode (see the GX-2009 Operator’s 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.
• Cal. Due (Days) — shows when calibration is due in days
(e.g., “Remaining 25 Day” means that calibration is due in
25 days, and “Now” means that calibration is due
immediately).
The Bump Test Record fields also include the following:
• Gas — Lists the target gas for which the Test Result and
Concentration readings are displayed.
• Test Result — Shows the gas reading resulting from the
bump test.
• Concentration — Shows the concentration values of the
applied gas.
• Bump Test Due — Indicates what day a bump test is due
for the instrument. If the instrument is due now, the box will
be highlighted in red.
