2.1 Users safety information
Read all these instructions first!
Save these instructions for later use.
Do Not Remove Connectors
To avoid personal injury or damage of equipment, do not remove the connectors for the
High Voltage supply, preamplifier supply, and the input connector until the High Voltage is
shut down and the device is switched off at least for 1 minute.
Do Not Remove Covers
Do not open the device before the power is switched off.
2.1.1 Power Source
This device is intended to operate from an internal accumulator set (high
performance Li-Ion battery) or together with an external wall adapter.
Furthermore the device can be powered directly from a high power USB port (up
to the maximum nominal input power of 2,5W).
Do not apply more than the specified voltage to the wall adapter. Usually it is 230VAC
nominal. The adapter must be in a good condition. Never use a damaged wall adapter!
2.1.2 High Voltage Supply
Make sure that the High Voltage connector and the High Voltage supply cable of
the detector are in a good condition before connecting them to the MCA166-USB
or before switching the High Voltage on. Do not allow anything to rest on the HV
cable.
Never insert objects of any kind into the High Voltage connector as they may touch the
dangerous voltage point. This might cause an electric shock or a damage of the device.
2.2 General Description
The MCA166-USB is an autonomous module. The device has its own battery and
provides power supply to radiation detectors. Together with a computer the MCA166-USB
forms a multi channel analyzer. The spectra are collected in the memory of the MCA166-
USB and are periodically transferred via a serial interface to the computer. The computer
is used to setup the MCA166-USB, to display and process the measurement results, and
to store the data. The design concept of the MCA166-USB also supports a Multi-Channel
Scaler mode.
For operation the MCA166-USB itself has only a power switch and a green LED indicator.
