19.3. Restarting
Restarting is to be carried out like the original start-up. Follow all steps described in this manual.
Before opening the water inlet, make sure that the flow is not impeded or interrupted anywhere. When
using assemblies that can hold several sensors, make sure that all holders are occupied or closed with
a blind. Make sure that all valves are in the right position (for example, inlet and outlet open, sampling
point closed). Check that all screw connections are sealed tight before applying pressure.
Sensors are delivered with a fix and tested C value. You do not have to determine the C value prior to
measurement. The tolerances in the C values are within 1.5-2% of the measuring range. For very precise
measurements the C value can be determined and calibrated using Potassium chloride solutions with a
known conductivity.
After installing the sensors, wait until all measurements are stable, and check if the measured values
are plausible, before activating the controller. Also check all settings, especially for controller and
alarm, and make sure that the feed lines are properly connected and undamaged.
Use all safety features the instrument provides, such as the alarm relay, the limits, the dosage check,
and the controller stop.
19.4. Decommissioning and disposal
If you want to take the measurement out of service for a while, mind the storage conditions listed in the
data sheets, especially regarding temperatures. Store sensors always in solution, preferably in 3M KCl,
never in deionized water or aggressive solutions. We advise to use for storage the protective covers in
which the sensors were delivered. If you want to use other beakers, use plastic instead of glass to
avoid damage to the glass membrane, and ensure that the storage solution always covers the junction.
Store instruments and cables in a cool, dry, and dark place, protected against dust.
If you want to dispose of the instrument permanently, mind that it contains electrical components that
have to be disposed of following national directives.
19.5. Facilitating functions
19.5.1. Store and load settings via SD card
You can store your settings on an SD card and reload them anytime to ensure that the settings are not
lost during maintenance.
This function can also be used to duplicate settings into other instruments of the same type and
parameter or to recover your settings after a software update or an upgrade via add-on. Additionally,
you can do all settings comfortably on your PC, using the Kuntze configuration software, and then load
the settings into the instrument via SD card. The configuration software is available free of charge.
