Adjusting and Measuring
SONO WZ
Translation of the Original Instructions for Use
Adjusting the raw density
The hand-held measuring instrument can
only be switched to the measurement
mode for measuring water content once
the adjustable parameters have been en-
tered.
Raw Density D (density):
Here, the raw density can be entered in
kg/dm³. This is important because it is di-
rectly included when calculating the water
content.
Characteristic (CHAR):
of the concrete formulation with 4 setting
possibilities:
coarse (negative correction),
normal (no correction),
fine (plus correction), or
special (negative correction with
gap grading)
Note: the mortar content in concrete
substantially affects this parameter.
General-Set (G-Set +/-):
Fine adjustment of the SONO WZ for
concrete type together with the type of
rock and core water.
Input max. ±50 l
Typical value: -10 l (2/3 from core water),
which is automatically subtracted during
measurement if the effective
water content (effective water) is to be
measured.
If the Darr water content is to be measured
with the SONO WZ, enter the G-Set with
a plus value, with 1/3 of the core water.
