2. Technical manual TLD-Irradiator is built in a portable condition housing. The front side of the housing contains the following modules from on the left of to the right: the electronic tax and control unit the thrust subject the calibration factor announcement. On the back is a cold equipment installation plug in combination with the in out rocker switch, the safeguard subject and the voltage switch as slidegate valve. - Page 5 During the calibration procedure the disk, propelled by an alternating current synchronous geared motor, turns with the elements which can be illuminated continuously under the opened source screen. With a frequency of 50 cycles per second the speed 1 rotation / minute is. With a frequency of 60 cycles per second the speed 1.2 rotations / minute is.

If the equipment is purpose-alienated used, the manufacturer takes for this no guarantee! - Page 9 4.2 Operating instructions In order to serve duly the equipment, first is to be clarified it, which kind of Tld elements are to be calibrated. If it concerns TLD maps, then the photograph plate is to be used for maps (card disc). Five maps can be put, with the map corner outward, on the plate.
- Page 10 When TLD chips and/or. TLD- sticks are calibrated, you take the plate with the blind holes arranged at the edge (combi disc), into which the elements are to be put down. Then the thrust subject is put to be pulled out up to the notice and the appropriate plate is put on the thorn.

- Page 12 Note Calibration data for other dosimeters and/or plates can be determined easily with an TLD-analyzer (e.g. Harshaw model 4000 TLD). The determined desired value can be entered by the appropriate manipulation of the keys at the counter. After effected input those, the ,,reset" key is to be pressed in order to put the counter exit back.
- Page 13 4.3 Error recognition and recovery If the red, lights up ,,shutter”-LED announcement with the start of the calibration process, the source screen did not open. Repeat the starting process after the equipment were completely switched off. If the Irradiator does not show the desired reaction after renewed switching on and operation of the push-button, please inform the service.
