NOTE:
When conducting the measurement procedure, be aware of the following rules and empirical values:
1. Never plunge the device at the same spot in the bucket
2. Delete individual measured values if they deviate significantly from the mean value.
3. An increase in the number of individual measurements leads to an increase in accuracy.
4. At the start of the measurement procedure, it is recommended to carry out a test measurement and then
delete this first individual value.
5.4 Measurement procedure for concretes with slump F5 and F6
NOTE:
When taking a sample of the concrete for filling the bucket, make sure that the concrete is not segregated
already during this procedure.
Use a 12 liter plastic bucket common in the construction industry. Do not use a metal bucket (this will affect
the electrical measuring field) and no larger bucket (this will result in non-desirable compression.
1. Only fill the bucket ¾ with concrete.
2. Plunge the probe head with the drawn-out tool shovel (made of
plastic) vertically at the edge of the bucket completely into the
concrete.
The shovel ensures that larger pebbles do not move to the side
of the probe head during the measurement, which could lead to
deviations or increased measurement values.
3. Slowly push the probe head with the black ceramic surface in front
to the opposite edge on the bottom of the bucket, with the handle
resting on the edge of the bucket (see red arrows). This ensures that
the concrete does not separate and that a representative concrete
mix is in good contact with the probe surface. Take a measurement.
4. Repeat this process 4 to 5 times, whereby the probe is inserted
about 45° to 90° at the edge of the bucket.

1. Never plunge the device at the same spot in the bucket
2. Delete individual measured values if they deviate significantly from the mean value.
