Figure 3 Basic Instrument with a Fixed Basic Plate
5.2.4 System of Exchangeable Measuring Plate
In some laboratories (e.g. in road construction laboratories) a large number of samples need to be measured
daily. Therefore, a special plate system for quick replacement was constructed. As a result, much working
time for sample preparation and cleaning can be saved.
The system of exchangeable measuring plate is shown in Figure 4 and consists of a base (1), an
exchangeable plate (2) and a grip (3). If necessary, additional exchangeable plates can be supplied on
request.
To decouple the exchangeable plate, place the exchange grip perpendicularly to the exchangeable plate on
the holder - small cuboid at the edge (see Figure 4). Thereby push the opening at the front of the exchange
grip into the holder so that the pin at the end of the grip points towards the exchangeable plate. Then, turn the
grip with the exchangeable plate to the right (counter clockwise). Now the exchangeable plate can be
removed upwards.
Note: The grip and the exchangeable plate should not be rotated 180°, both can get in touch to the hand and
cause burns.
To connect and fix the exchangeable plate to the basic plate, set up the plate centric on the holder and turn
fixed the grip to the left (clockwise). In this case, turn the exchangeable plate until a stop is reached. If
pressed lightly in the opposite direction, the plate should not come off immediately. Then the grip may again
have turned upwards and be pushed forward slightly for removing.
