CAUTION When lowering the instrument head make sure that the immersion tube and/or the
temperature sensor with its holder (see
the sample container and break it, or make it fall over.
 To raise the instrument head
1. Hold the instrument head with the left hand and loosen the knurled knob screw of the instrument
holder with the right hand.
2. Lift the instrument head upward along the rod into the desired position, then tighten the knurled
knob screw.
By adjusting the radial position of the three clamps blocks (see
sample containers with a diameter varying from 55 to 190 mm can be securely clamped to prevent
unwanted movement of the container.
 To mount a clamp block on the base plate
1. Place the nut (with the flat side facing downwards) in one of the channels at the bottom side of one
of the slits in the base plate.
Figure 5.
2. Place the block on the upper side of the slit in the base plate and insert the spanner bolt through
the hole in the block and through the slit.
3. Screw the spanner bolt into the nut, but do not tighten it.
 To adjust the clamping force of a clamp block
1. Make sure the spanner lever can be swiveled up/down and rotated freely. If necessary screw the
spanner lever upwards (counterclockwise) to achieve that.
2. With the spanner lever kept upright with one hand, screw the knurled ring upward
(counterclockwise) against the spanner lever until a stop with the other hand (without using much
force).
3. With the spanner lever kept upright, screw the spanner lever downward (clockwise) until a stop
(without using much force).
4. With the spanner lever kept upright, screw the spanner lever upward (counterclockwise) for about
two revolutions in such a position that the lever faces to the rim of the base plate when it is
swiveled into the horizontal position.
5. Screw the knurled ring downward (clockwise), for about two to three revolutions, until swiveling
the spanner lever downward (at an angle of about 45°) results in clamping the block to the base
plate.
