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
measures no throughput for about one hour, it automatically switches off.
During operation with the optional power supply unit, the combined meter
does not automatically switch off and cannot be switched off manually. If the
combined meter has switched off automatically, it will automatically restart
once the throughput (> 2 l/min) resumes. If the combined meter is switched
off using the ON/OFF key, it will not restart automatically.
Auto mode
Press the key
twice in quick succession to start automatic monitoring by
the combined meter. The
symbol is shown to indicate that monitoring
has been enabled. In auto mode, the meter only takes measurements when
water is actually passing over it. If the throughput is interrupted, the meter
continues to show the last captured value. When a throughput is present, the
meter takes a new reading of the conductivity value after every 10 litres and
displays it. If the limit is exceeded in two successive measurements, the
display continuously flashes red and an acoustic alarm sounds. In addition,
