Unit key
Use this key at any time to switch between electrical conductivity (µS / cm)
and TDS (total dissolved solids) as well as between °C and °F. The first two
are units of measurement for the amount of minerals dissolved in the water.
Most European component manufacturers use the unit of measurement
µS / cm (microsiemens per centimetre). Water hardness at the output of
the refill device can be determined using the following rule of thumb: 1 °fH
corresponds to approx. 20 µS/cm or 1 °dH corresponds to approx. 35 µS/cm.
Sequence of units: µS/cm -- °C | µS/cm -- °F | TDS -- °C | TDS -- °F
ON/OFF key (MANU/AUTO)
Press the key once to switch on the combined meter. The water quality is
measured for 10 seconds and compared to the set limit. During measuring,
the screen backlighting is blue and the conductivity value is displayed. If the
measured value is below the set limit, everything is OK. If the measured value
exceeds the limit, the display flashes red, an alarm signal sounds and the
floating contact switches over (only when using the optional power supply
unit). The current throughput and the water temperature, as well as the
total water throughput, are continuously displayed. Press the key for approx.
3 seconds to switch off the device. If the combined meter is switched on and
