  • Page 7: Introduction

    INTRODUCTION The Accu-Dose™ system measures dose, time, and more. Measurements are processed and displayed by a microprocessor-based control unit. To eliminate cable noise, dose sensors connect to the control unit via a 4-m cable that carries only digital signals and operating voltages. Dose is measured using ion chamber or diode-dose sensors connected directly to a digitizer-electrometer.
  • Page 8 process measurements performed by the Accu-Dose™ System. XLPRO, an Excel add-in, uses this capability to produce reports, graphs and to automate measurements. The Accu-Dose™ may be operated from a rechargeable NiMH battery, from alkaline C cells, or from mains power. The control unit is shown on page 5.
  • Page 9 Measurement results are presented on the display and are available in digital formusing the USB connection (see XLPRO page 29).

  • Page 14 Ion Chamber Dose Timing Specifications Measuring time (pulse width) The Auto-Dose mode Accu-Dose Advanced only provides a pulse width (time) measurement capability when you use either ion chambers or dose diodes. For ion chambers, the 10X6-6 and 10X6-6M are recommended. The range of pulse width extends from 10 ms to 9999s.
  • Page 15 For time less than 10ms, dose diodes are recommended. For the DDX6 diodes in Auto Dose the width uncertainty is 1.2 ms plus 0.1% of width over a range from 5 ms to 9999 s. Minimum dose rate is 102 μGy/s or 700 mR/min.

  • Page 18 Connect the ion chamber digitizer: Align the red dots of the smaller round connector of the sensor cable and corresponding connector of the digitizer and push to engage. Pull on the ribbed metal ring to disconnect. Connect the ion chamber: Connect the ion chamber to the larger circular connector on the ion chamber digitizer.
  • Page 20 Connect the battery charger: The batteries are fully charged when they leave the factory and may be charged before use. The charger connects to the rear of the control unit. Plug it into an ac outlet. The charge indicator should turn orange indicating the battery is being charged. The instrument can operate while charging.

  • Page 21: Operation

    Operation Turn on the Accu-Pro™: Press the green power button. A beep sounds and a set of vertical rectangles marches across the display to assure it is operating, the calibration date is displayed, and self-test is performed. During turn-on the control unit reads the type and calibration factors of each sensor, measures the ion chamber temperature and the ambient pressure.
  • Page 22 When it reaches zero, pressure and temperature display: Press 99.2 kPa Temp 20.1 deg C The top line of the display will then show: Change or SELECT and the second line will show setup or whatever measurement mode was active the last time power off occurred. If self-test is unsuccessful, a failure message is displayed.

  • Page 23: Display

    Display Instrument operating status and measurement results are shown on the 2-line display. In some cases there are more measurements than will fit on 2 lines. Press selectto scroll additional readings onto the display. Characters at the left side of the display have special meaning: For dose measurements: ? indicates dose-sensor signal was outside calibrated range.

  • Page 24: Sounds

    Sounds: A short beep signals a key-press. A long beep signals an error. Making a measurement: The UP and DN arrows move through the main menu. The top line of the display continues to show Change or SELECT while the second line shows the measurement you may select. Pressing select starts the measurement.

  • Page 25: Dose Rate

    Dose Rate Use UP or DN to reach Dose Rate then press select. The display will briefly show 6cc Corr 1.02 measuring zero after which it will become [ Dose Rate 0.0 mR/min The up arrow indicates low-sensitivity mode. Press and hold test (or make an exposure). The display becomes [ Dose Rate 999.5 mR/min...
  • Page 26 Once the measurement has been completed, the display retains the values. A subsequent exposure does not replace them until the measurement is complete. The > appears to the left of the exposure value to indicate signal-present. When it disappears, a beep sounds and the new reading is displayed.

  • Page 27: Making Ion Chamber Measurements

    MAKING ION CHAMBER MEASUREMENTS 1. Allow the system to reach equilibrium by selecting dose rate mode and waiting at least three minutes. Do not touch digitizer. One does not need to shut the system off when replacing chambers, however, do not disconnect the chamber when actual measurements are being made.
