Saftey precuations and intended use of the
Chamber Adapter
Always remember to make all connections when the power is off.
After power off the bias voltage drops slowly due to the high impedance of the Chamber Adapter.
This means that high voltage is present on the connector up to 1 minute after power off.
The Chamber Adapter is only intended for use together with the Piranha and Cobia.
The Chamber Adapter is only intended for use together with ion chambers that works on positive
bias level.
Do not connect an ion chamber that is not intended for +300 V bias voltage, to the Chamber
Adapter.
The Chamber Adapter is only intended to be used with ion chambers that has a LEMO connector or
with available adpaters from RTI Group. AB.
RTI Group AB takes no responsibility for misuse of the Chamber Adapter or use together with
products that the Chamber Adapter is not intended for.
RTI Group AB assumes no responsibility to customers not following these safety precautions.
Note! The Chamber Adapter is intended for service and quality control of diagnostic X-ray
equipment. It is not intended for use during or together with diagnostic examinations of patients.

1 Introduction
The Chamber Adapter is an external electronic bias supply for the Piranha X-ray multimeter and Cobia. The
Chamber Adapter makes it possible to connect ion chambers with a Lemo connector to the external input of
the Piranha. The Chamber Adapter is primarily designed for CT and mammography applications but can be
used for other applications.
For the purposes of this documentation, the expression ”electrometer” refers to the electrometer of
the Piranha or Cobia.
The Chamber Adapter makes it possible to choose between solid state detectors and ion chambers depending
on the measurement application. The calibration factors for the ion chamber(s) used with the Chamber
Adapter are stored in memory located in the connector that connects to the Piranha or Cobia. Up to four
different calibration factors can be stored in memory. The utility program "RTI Detector Manager" can be
used to add/modify calibration factors.
