Readout unit EDAG 02 for ED 150
The ED 150 can be either used as „stand alone“ dosemeter or together with the readout unit EDAG 02 as system dosemeter, too.
Via the RS 232 interface, the EDAG 02 has to be connected with a computer. The software is Windows compatible and serves for reading out measured data from the ED 150 (e. g. dose values) respectively for programming certain functions of the ED 150 (e. g. alarm thresholds, personnel numbers) and to represent these data graphically or in tabular form. All dose data can be processed with MS-Access.
The communication between the ED 150 and the readout unit is effected by the optical interface of the ED 150.
