| Note: |
| |
Values for ion chambers are calculated using
nominal sensitivities: 15 cc: 2.4 x 10 8 R/C 150 cc: 2.4 x 10 7 R/C Very
Low Dose Rate effective range at 5% resolution steps. At 60 frames/sec
(1 to 120 frames/selectable). IEC 61674 effective range at 1% resolution
steps. |
|
| Measurement modes: |
| kVp/Dose/Time: |
Single shot, direct beam measurement of
exposure, kVp, and time. Auto-ranging across three decade ranges. Auto
reset between exposures. Display update after each exposure |
| kVp/Rate: |
Simultaneous measurement of kVp and exposure
rate |
| Full sensitivity dose: |
Auto-ranging across five decades of sensitive
ranges. Automatic drift & offset compensation, and automatic
post-exposure display hold |
| Full sensitivity rate: |
Measurement range covers a span from low level
image intensifier measurements to unattenuated direct beams. Automatic
offset compensation and nonlinear filtering. Autoranging provides five
decades of sensitivity ranges. Display updates once per second |
| Very Low Dose Rate (VLDR): |
This mode is only for making very low dose rate
measurements. Nonlinear digital filtering and autoranging provide five
decades of sensitivity ranges. Display updates once per second. In this
mode, automatic current offset and drift compensation is disabled. As a
result, the system can display very low dose rates |
|
| Power requirements: |
| |
30-hour life with six AA alkaline batteries.
Automatic power-down after user-selected period of unattended operation
(5-255 minutes). An AC adapter is supplied with each 35050AT. When the
AC adapter is in use, the auto power down feature is disabled, providing
continuous operation. User selections for ion chamber, units, kV filter
pack, temperature, pressure, and frame are stored in nonvolatile memory
before automatic turnoff; eliminates manual re-selection at power-up |
|
| Bias voltage supply: |
| |
Fixed electronic bias (~300 V). Bias voltage is
removed from triaxial input connector at instrument turnoff |
|
| Customization: |
| |
Allows user to modify contents of nonvolatile
memory including ion chamber and kV filter pack conversion factors,
temperature and pressure units, radiation units, and power down
interval. A field customization software program is included for use
with an IBM®-PC or compatible |
|
| Display: |
| |
Two-line, 20-character alphanumeric PLED
(polymer LED), with 0.5 cm character height. Indicates all ion
chamber/kV filter pack identification information, numerical measurement
results, battery level, calibration date and other information |
