2.1 Function of the Chamber Adapter
The Chamber Adapter is an ion chamber adapter with a built-in bias voltage supply for use with ion chambers
that have a Lemo connector and operate on negative bias voltage, +300 V DC.
The Chamber Adapter is powered ON with the black button to the right.
The green power LED indicates that it is on.
The red LoBat LED indicates when it is low battery and charging is required.
Note: Do not measure when the LoBat LED is on since it may lead to inaccurate
measurements.
The yellow Bias LED indicates that +300 V is present. The bias is activated
when the Chamber Adapter is turned on. The bias is turned off when the
Chamber Adapter is turned off.
The Chamber Adapter has a rechargeable battery. The Piranha power supply (not the Cobia power supply)
can be used to charge the Chamber Adapter. To charge the Chamber Adapter:
1. Turn off and disconnect the Chamber Adapter from the Piranha.
2. Connect the Piranha power supply to the Chamber Adapter and make sure that the main switch is in the
off position and the Charge LED is on.
3. When the battery is fully charged the Charge LED goes off.
2.2 Connecting the Chamber Adapter
Make sure the Chamber Adapter is powered off before connecting the ion chamber.
1. Connect the ion chamber to the input on the Chamber Adapter (Lemo connector).
2. Power on the Chamber Adapter. The bias is now applied to the ion chamber.
3. Connect the Chamber Adapter to the Piranha or Cobia.
4. Make the necessary settings/selections in Ocean 2014 or in QABrowser. The sections "Measurement with
Ocean 2014" and "Measurement with QABrowser" contain more detailed instructions on how to use the
Chamber Adapter in Ocean 2014 and in QABrowser.
