2.7.4 Making Exposure or Exposure Rate Measurements without a Model
35080/80A/80B kVp Divider
The Model 35050AT Dosimeter can be setup to make only exposure measurements by selecting the filter
pack type “35080/80A Not Used”. This filter pack selection turns off the Model 35050AT Dosimeter's kVp
divider port, and causes only the exposure line to be displayed on the measurement screen.
Selecting any one of the other filter packs enables simultaneous exposure and kVp measurements.
2.7.4.1 Advanced Measurement Options
Exposure Reset – Allows the user to turn the Automatic Exposure Reset feature on or off.
When the Exposure Reset option is set to Automatic, Model 35050AT Dosimeter automatically resets
between exposures; exposure start and end detection are based on the exposure rate level crossing a
0.25 pA threshold. The instrument treats exposures separated by less than two seconds as single
exposures.
When the Exposure Reset option is set to Manual, the Reset/Measure button may be depressed between
exposures to clear the display. When the Manual Reset option is active, the symbol appears in the
upper right corner of the display. Exposure start detection is based on the exposure rate level crossing a
0.25 pA threshold but the exposure measurement may only be reset by pressing the Reset/Measure
button. The manual reset feature is only active in the Full-sensitivity Exposure mode.
