9. You can enter the desired mass concentration using the
[Arrow keys]
.
CAUTION!
– Observe the decimal point.
–
The mass concentration is affected by both
changes in the stroke rate and the stroke length.
The value in the continuous display cannot be freely
changed using the [Arrow keys] as the least significant
figure values changes in jumps, the value of which
depends on the input data.

The "Concentration input" in
‘BATCH’
operating mode, is intended for
metering a substance into a storage tank so that it then exists in the con‐
tainer with a defined mass concentration (batching of a solution. Do not
forget to stir!).
n the medium in the storage tank has the same density as water (1 kg/L
≜ g/cm

)
n the mass concentration of the feed chemical is known - see the feed
chemical safety data sheet (e.g. with 35 % sulphuric acid: 35 %)
