Channel 1 Calibration Status The instrument displays Calibrated
when the plug-in module has been calibrated in the current mainframe slot
otherwise the instrument displays Uncalibrated. Once a plug-in is
calibrated, the temperature difference (∆Temp) between when the plug-in
was calibrate and the current temperature is displayed. The plug-in module
will met dc accuracy specifications as long as the ∆Temp is within the range
of -5 °C to +5 °C. Also displayed, is a list of the plug-in module’s model
number, serial number, date of last calibration, and time of last calibration.
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.
Calibrate probe
Connect a voltage probe to the plug-in and then press:
Calibrate probe
Continue
The instrument calibrates to the tip of the probe by setting the probe
attenuation to the actual attenuation ratio of the probe. The instrument also
automatically compensates for any offset that the probe may introduce.
