5. Operating Principle
The KOBOLD hand-held conductivity measuring units of model HND-C110 is a
compact conductivity measuring units with solidly connected probes that can be
used universally. Due to the double display, both the conductivity and the
temperature value can be displayed simultaneously. The HND-C110 model offers
functions like minimum/maximum value memory, hold function, auto-off function,
and AutoRange (automatic adjustment of the optimum measuring range).
Due to the high temperature dependency in conductivity measurement, the
manual measuring unit has automatic temperature compensation.
With the improved unit HND-C110, the determination of resistance, salinity and
TDS are also part of the scope of functions.
6. Electrical Connection
6.1 Mains operation:
When using a power supply unit please note that operating voltage has to be 10.5
to 12 V
DC
. Do not apply over-voltage!! Simple 12 V-power supply units often have
excessive no-load voltage. We, therefore, recommend using regulated voltage
power supply units. Trouble-free operation is guaranteed by our power supply
HND-Z002. Prior to connecting the plug power supply unit with the mains supply
make sure that the operating voltage stated at the power supply unit is identical to
the mains voltage.
