Last Calibration Window • 71
NOTE: If a unit is calibrated using One Cal in the instrument’s Calibration 
Mode (see the GX-2012 Operator’s Manual or Gas Tracer 
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). If the instrument 
is due now, the box will be highlighted in red.
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.
It is not possible to print any information when the Calibration Record/
Bump Test Record view option is selected.
To view and print all past calibrations for an instrument, see “Calibration 
History” on page 29.
