n
The display rises to the red section, while all yellow LEDs are
on: Maximum compaction with this vibratory plate has been
reached.
n
The red status-LED lights permanently, no other LED lights up:
The Economizer does not detect any vibration.
n
The red LED is flashing: Diesel vibration frequency is too low.
In order to obtain comparable Economized measuring values,
the vibratory plate must work with a predetermined frequency.
Measuring values obtained with low frequency cannot be com-
pared with values obtained with high frequency.
n
The displayed measuring values are not plausible. weak spots
may also be located under the layer to be compacted and thus
adversely affect compaction of the layers above. In unfavour-
able cases an excessively varying material composition or
moisture can influence the measuring results.
Check the sensor on the base plate for tight fit! Both
screws must be tight.
n
Influence of the water content in the soil on the Economizer:
Display of reduced measuring values in case of too dry or too
moist material.
n
Influence of extension bars on the measuring value: Assem-
bling or removing extension bars changes the contact area and
the vibration amplitude. A generally valid statement about the
influence on the measuring result cannot be made.
