ADVANCED THERAPY DOSIMETER
MODEL 35040
FEATURES
The Advanced Therapy
Dosimeter is unparalleled in its fundamental performance and offers exceptional
features that enhance the quality of the data.
- Simultaneous measurement and optional
display of dose, dose time, and dose rate, as well as display of average
current/rate, accumulated charge/dose, and computed values.
- User selectable automatic computations
using ion chamber calibration values and air density correction.
- Retention of last set-up upon power-down.
- Automatic power-down after user-specified
time period, when operating from battery supply.
- Annunciators warn of low battery, low
bias, and operational errors.
- Large capacity battery provides eight
hours of continuous operation; fast recharge in less than three hours,
even during operation.
- AC line operation over the range of 90VAC
to 265VAC and 47Hz to 63Hz without operator intervention.
- Charge and current calibration factors
entered by calibration laboratories at user's option. User entry of ion
chamber calibration factors.
- Front and rear panel ion chamber
connections.
- Measures in dose and rate units, as well
as Curies and Becquerels units of activity.
- Automatic reset and hold of measured
values between exposures.
- Front panel adjustment of exposure
threshold and user disable of threshold to permit manual operation.
- Optional carrying case available.
FRONT
PANEL FEATURES
Power On/Off Key: All front panel settings are stored
at power-down and recalled at power-up.
Test Function Key: Sequence of screens to display
firmware revision, last calibration date, leakage and current, bias voltage and
battery voltage level, and charge and current calibration factors.
Detector Select Key: Up to 32 user-entered ion chamber
calibration factors selected. Descriptive text, units, and calibration factors
are displayed.
Air Density Key: User entry of ambient temperature
and pressure; displays calculated air density correction; symbol appears on
screens when air density correction is active.
Units Select Key: User selection of rate measurement
time base (s, min, and hr).
Bias Select Key: User selection of up to 11
user-programmed ion chamber bias voltage settings from -500V to +500V; displays
measured output bias voltage.
Reset/Measure Key: Displays measurement screen; resets
displayed charge and dose measurement values to zero and re-initializes the
measurement system. Up and down arrows select up to 16 user-designed
measurement screens.
4-Line by 20-Character
Vacuum Fluorescent Display: Provides excellent visibility in all lighting conditions.
