4. Operation
The dosimeter is activated by means of the power switch. The user is then requested to remove
any measuring film still in the measuring head and to press any key. Now calibration of the
device takes place: the red and green intensities are adjusted to a particular value. Because
optical components are subject to drift, you should switch on the device 30 min before use and
then recalibrate it after the half hour. In this way, accurate measurements are achieved.
Once calibration is complete, the device is ready to perform measurements. When a radiated
film (see item 10) is inserted, a dose reading immediately appears on the display. A constant
measured mean value is displayed after 8 to 32 measurements. Constant values are identified
by a colon displayed before the dose reading (after 8 measurements) or an asterisk (after 32
measurements).
