Unit key
Use this key at any ti me to switch between electrical conducti vity (µS / cm)
and TDS (total dissolved solids) as well as between °C and °F. The fi rst 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 centi metre). Water hardness at the output of
the refi ll 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 backlighti ng is blue and the conducti vity value is displayed. If the
measured value is below the set limit, everything is OK. If the measured value
exceeds the limit, the display fl ashes red, an alarm signal sounds and the
fl oati ng contact switches over (only when using the opti onal power supply
unit). The current throughput and the water temperature, as well as the
total water throughput, are conti nuously displayed. Press the key for approx.
3 seconds to switch off the device. If the combined meter is switched on and
