in the form of a key press, exposure, or RS-232 command for the duration of the power down interval, it
will turn itself off. This interval must be in the range of 5 to 255 minutes. An entry of zero will disable the
automatic power down feature.

Ion Chamber Calibration Units (ICCU)
The Ion Chamber Calibration Units Item defines the units in which the ion chambers in the 35300A
Detector were calibrated. The default is roentgens per nanocoulomb.
This means that the Ion Chamber Calibration Factor (ICCF) given on the Display Calibration Items screen

sieverts per nanocoulomb, and rads per nanocoulomb.

TRACKER Display screen. The choices are roentgens, grays, sieverts, rads, and monitor units. The
default is rads.
Display Units Conversion Factor (DUCF)
The 35360A TRACKER Display uses the Display Units Conversion Factor (DUCF) Item to convert the
output of the ion chambers (in units defined by the Ion Chamber Calibration Units) to the units required for
display (defined by Display Units).
You must set the Display Units Conversion Factor
correctly and accurately to convert the ion chamber
output to displayed units. The default is 0.879
rads/R.
