Aer 5400

12. Operation conditions

The instrument has been designed as a robust unit for portable use in nuclear and mining facilities.
Because of the sampling method, the detector head is directly exposed to the ambient conditions.
Therefore, the user should mind a few limitations.
•
The temperature range from 0°C to 50°C should not be exceeded. An extended range can be
provided on request.
•
Condensation of water must be avoided. After strong temperature changes (moving a cold
unit in warm environment) the instrument should be tempered for a while before using.
•
Avoid beats onto the enclosure or detector head. The microphonic (piezo-electric) effect
generates electronic signals similar to decay events. The instrument is equipped with
dynamic shock suppression (electronic pulse shape analyses). Frequently shocks or
permanent vibration must still be avoided.
•
Do not use any strong source of electro-magnetic fields in the immediate vicinity of the
detector head (e.g. mobile phones, Wi-Fi adapter/router).
•
The instrument should never be operated without filter. Particles in the air loop resulting in
an increased abrasion of the pump.

13. Communication with a PC

The instrument is equipped with an internal USB interface for service purposes which is located
directly at the cover of the display unit. A nine-pin SUB-D connector at the bottom of the enclosure is
configured either for RS232 or RS485 (bus) interface depending on customers request. Both
interfaces can be used for all required data transfer from and to the instrument. If the USB interface
is connected, the RS232 interface will be disconnected (USB priority). The standard transfer rate is
9600 baud. If no sampling is in progress, the transfer speed can be increased significantly using the
"Card Reader" function. Push simply the touch area at the top of the main menu to enter this mode.
Please make sure that the card reader mode has been selected in dVISION too. Increased transfer
speed is only available for the USB interface.
The instrument offers a simple proprietary communication protocol which allows the user to access
the unit by own software solutions. For more detailed information please contact the manufacturer
or your retailer.
