solution is guaranteed .
5 . the measuring result will not be affected by the
temperature of the cooling solution .
6 . after measuring has occurred, clean the included
pipette [10] and the refractometer thoroughly .
* In europe, Propylene is primarily used as an anti-freeze agent .
** Outside of europe, ethylene is primarily used as an
anti-freeze agent .
Measuring Process for Windscreen Washer
Fluid-Check
1 . the measuring process is identical to the one
used for the anti-freeze-check .
2 . For the windscreen washer fluid-check [c], the
measured value can be read in °c on the measu-
ring scale and indicates a guideline value, as
the composition of individual anti-freeze agents
varies .
3 . after measuring has occurred, clean the included
pipette [10] and the refractometer thoroughly .
Measuring Process for determining Battery
Acid Density
1 . Instead of the anti-freeze solution, apply a little
battery acid to the prism surface [2] by using the
pipette [10] .
2 . take readings for the acid density in g/cm 3
(kg/l) by using the light-dark-border on the
measuring scale for determining [a] “- / +“ the
battery acid density .
3 . the scale [a] is divided into three areas to deter-
mine the battery state of charge (sOc) .
recharGe = replace/recharge (<1 .20 g/cm³);
Battery state of charge (sOc)
~50%
FaIr = acceptable
(1 .20 to 1 .25 g/cm³); Battery
state of charge (sOc) ~75%
GOOD = good (>1 .25 g/cm³); Battery
state of charge (sOc) ~100%
