Accu-Gold measurements and Feature comparison
The following are measurements that can be assigned to any cell when creating custom profiles. These
are grouped by the measurement source. Note that not all measurements are available when using the
Nugget or Touch WiFi mode.

Definition
Digitizer
Air Pressure yes yes
The atmospheric corrections compensate for the effects of
variations in the current temperature (T in C) and pressure
(P in kPa) on an unsealed ion chamber and uses the
following equation:
Displayed value = (101.3/P) * ((T + 273.15)/295.15) *
Instrument value
Ave. Pulse Duration yes yes
Average duration of pulses.
Duration yes yes
Exposure duration from start to stop trigger. If pre-pulse
detection was activated, duration is the duration of the main
signal without pre-pulse.
Pre-Pulse Detected yes no
True if pre-pulse detection was active and pre-pulse signal
was detected.
Pre-Pulse Duration yes no
Duration from detection of pre-pulse start to main signal
start.
Pulse Count yes yes Measurement pulse count.
Pulse Duty Cycle yes yes Pulse duty cycle.
Pulse Frequency yes yes
Pulse frequency
Pulse Rep. Period yes no
Measurement pulse repetition period.
Total Duration yes no
Exposure duration from start to stop trigger, ignores pre-
pulse detection.
Trigger Level yes yes
Trigger level used for this measurement.
Trigger Sensor yes yes
Sensor that was trigger.
Typical Pulse Count yes no
Measurement pulse count ignoring scout pulse.
Multi-Sensor
Anode yes yes
Tube anode setting used for this measurement.
Average kV yes yes
Average kV is derived from the ratios of the outputs of
diodes in the multi-sensor, where these averages use the
entire region of interest.
Biased Average kV yes no
The average value of kV in the region of interest above an
adaptive kV threshold.
Calibration Description yes yes
The name of the calibration and correction that was used
for making the measurement. e.g. "Diagnostic", "Standard",
"Mo Mo", "Mo Mo GE" etc.
Dose yes yes Dose Integral
Dose / mAs yes no Dose / mAs
Dose / Pulse yes yes
Dose / Pulse
