Extracted measurements have the same measurement index as the parent, but include a decimal value.
Additional extractions of the same measurement will increment the decimal (1, 1.1, 1.2…etc.).
List View and export will also provide the results as a sequence.
Note: Waveforms are limited in length to 300 seconds (5 min) in USB mode, and 40 seconds when using
WiFi mode. A measurement can continue past this but a waveform will not be available and the message
“Extra Long Mode” will be displayed. Measurements lasting up to 2.45 days are possible.
AGMS DM+, D+, M+ will display dose information when filter is out of range
Previous versions of Accu-Gold did not display multi-sensor dose information when kV data could not be
obtained when the reported filtration was out of range (e.g. >40 mm Al eq. for diagnostic x-ray). This
information is now available for all Accu-Gold “Plus” multi-sensors. This capability is especially useful for
copper filtered diagnostic beams (> 1mm Cu). For mammographic beams, aluminum filtration can now be
added up to 1 mm without loss of dose accuracy (± 5%). Thus, manual hvl measurements can be
performed with aluminum filters. Although dose will continue to be displayed with >1mm Al added filtration,
the uncertainty may increase to >10% for filtrations exceeding 2mm Al. Note: there is no warning that the
uncertainty has exceeded Radcal’s specification for dose once the 1 mm Al limit is reached.
