Figure 2-3. A typical Cal Status display.
Current Date
This is the current date and time. You can compare this to the last plug-in
module calibration time. That way you will know how long it has been since
the last plug-in module calibration was performed.
Current Frame
∆
Temp
This is the temperature change on the inside of the instrument since the last
mainframe calibration was performed. A positive number indicates how many
degrees warmer the mainframe is currently as compared to the temperature
of the mainframe at the last mainframe calibration.
Channel 1
Calibration
Status
The instrument displays
Calibrated
or
Uncalibrated
, depending on
whether the last plug-in module calibration is still valid. A calibration can be
invalidated if:
• The mainframe has cycled power.
• The plug-in has been repaired, reprogrammed, or removed from the
mainframe.
• The instrument’s operating temperature has changed and remains more than
5
°
C from the temperature at which the Plug-in calibration was performed.
Uncalibrated
indicates the plug-in module vertical calibration is invalid.
