Abstract
Abstract A hand held device for measurement of radiation includes a sensor unit and digital processing unit between the sensor unit and a digital display unit. The sensor unit together with a signal processing unit and the digital display unit are accommodated in a common housing, and a position-dependent switch together with a switchable coding circuit are provided, by means of which the digital display unit may be switched so that it can be read in a position reversed by 180° in a plane thereof.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
100 words
A device, particularly a hand-held device for measurement of radiation, particularly UV-radiation, with a sensor unit, and with a signal processing unit between the sensor unit, and a digital display unit characterized by the sensor unit (11), together with the signal processing unit (16) and the digital display unit (21) being accomodated in a common housing (26), and in that a position-dependent switch (37) together with a switchable coding circuit (19) are provided, by means of which the digital display unit (21) is switchable so that it can be read in a position reversed by 180° in a plane thereof.
Claim 2
Independent Claim
100 words
A device, particularly a hand-held device for measurement of radiation, particularly UV-radiation, with a sensor unit, and with a signal processing unit between the sensor unit, and a digital display unit characterized by the sensor unit (11), together with the signal processing unit (16) and the digital display unit (21) being accomodated in a common housing (26), and in that a position-dependent switch (37) together with a switchable coding circuit (19) are provided, by means of which the digital display unit (21) is switchable so that it can be read in a position reversed by 180° in a plane thereof.
Claim 3
Dependent Claim
61 words
Device according to claim 1, characterized in that in an approximately parallelepiped hand-held housing (26) there is disposed a sensor unit (11) on a front side (27) thereof, said front side having a small surface, and in that there is disposed perpendicularly thereto a digital display unit (21) on a longitudinal side (28) thereof, said longitudinal side having a large surface.
Claim 4
Dependent Claim
85 words
Device according to claim 1, characterized in that the switchable coding circuit (19) is formed by a logic matrix circuit, whose inputs are connected with a control circuit (18) for the digital display unit (21), which latter is formed as a 7-segment indicating unit, said inputs being in turn connected through a respective logic modular block (41, 42) with two mutually point-symmetrical segment indicating units (31) of the display unit (21), and that the segment indicating units (31) are controlled from the position-dependent switch (37).
Claim 5
Dependent Claim
23 words
Device according to claim 3, characterized by the control circuit (18) being connected with a key (22) for storage of the instantaneous display.
Claim 6
Dependent Claim
14 words
Device according to claim 1, wherein said sensor unit further contains a radiation filter.
