| 摘要 |
The invention relates to a monitoring device for a measuring device (100), comprising an indicator (120) and a sheet (110). Said indicator (120) and sheet (110) have a reflection behaviour for light which are different from each other. Said device comprises at least one first detection means (210) comprising a light source (220), and a sensor (230), at least one securing means (250) for securing the detection means (210) to the measuring device (100). Said detection means (210) can be arranged, with the aid of the securing means (250) such that the first sensor (230) can capture the light (228) reflected by the measuring device (100), the light being emitted by the first light source (220). |
