3.3.2 Calibration solutions
WARNING!
Incorrect measurement following the use of an incorrect or expired calibration solu-
tion for recalibration.
If an incorrect or expired calibration solution is used for recalibration, the measuring accura-
cy of the instrument may be affected. If recalibration cannot be made due to the loss of the
calibration solutions, the measuring accuracy of the instrument also cannot be guaranteed.

Always ensure that the correct calibration solution is used (e.g. pH 4).

Pay attention to the indicated expiry date and order a new calibration solution in good
time.

Always store the calibration solution according to the prescribed storage conditions (in a
dark place at room temperature).

Store the calibration solution in a defined location.
3.4 Residual risk
WARNING!
According to the risk assessment of the applied safety directive DIN EN 61010-1, the
following residual risks remain:
Overflow in the water circuit. This risk can be minimized with the following
measures:

Set up the system in locations where water drainage is guaranteed.

Use shut-off valves at the sampling point and sample return point.
Incorrect display of measuring values. This risk can be minimized with the following
measures:

Use an access code to prevent unauthorized persons from changing the parameters.

Perform the specified servicing duties.
In the event of faults, the surface of the pumps can become hot. The risk of injuries
can be minimized as follows:

Do not touch surfaces that are marked with the “Hot surface” warning symbol without
gloves.
