    1. Introduction 1.1 RDS-31iTXSD S/R Multi-Purpose Survey Meter The RDS-31iTxSD Multi-purpose Survey Meter continues the line of the MIRION survey meters offering modern design and approach to a wide range of radiation monitoring applications. RDS-31iTxSD is a small handheld, battery-operated survey instrument utilizing an energy compensated single large PIN diode as a primary detector.

  • Page 6: Taking The Instrument Into Use For The First Time

    This allows the alarm to be triggered in case a too high dose rate or an accumulated dose is measured. The RDS-31iTXSD is ready for use after the batteries (2 x IEC LR6/AA) have been installed. 2 Taking the Instrument into Use for the First Time 2.1 Inserting Batteries...
  • Page 7   The instrument uses two IEC (LR6/ HR6) AA-size batteries. The use of alkaline batteries is recommended, but rechargeable NiMH batteries can also be used. The polarity of the batteries can be seen in the picture below. It is also engraved in the bottom of the battery compartment. Insert the batteries and secure the battery cap.
