7. Repeat above steps for each of the other A/D voltage levels. Following
the last A/D Calibration, the system advances to the Calibration Wizard -
kVp Calibration tab.
kVp Calibration Tab
The KV Calibration procedure calibrates the generator to verify accurate sys-
tem measurement of peak tube potential (kVp). The generator’s ability to
measure peak tube potential accurately is verified using a pre-calibrated kVp
meter (Dynalyzer or equivalent) as a benchmark. Proceed as follows:
1. If not already done so, access the Calibration Wizard - kVp Calibration tab
(see Figure D-16).

WARNING! To avoid injury to personnel, ensure
that system power is removed prior to making
and removing any electrical connections.
2. Factory Reset check box - when selected, will reset kVp Calibration val-
ues to factory default settings. This normally should not be selected; it
should only be selected when calibration values are extraordinarily out-of-
range (usually signifying a hardware or software abnormality).
