Page 5: Operating Principle
HND-C110 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). -

Page 9: Start Operation
If the range selection is set to „Auto Range“, the range with the best resolution is automatically selected. However, interface operation requires a manual/fixed selection of the measuring range from the table above (No interface operation with Auto-range!). HND-C110 K05/0422 page 9... -
Page 10: Resistivity Measurement
This may be done by comparison with known reference solutions or by actually evaporating a certain amount of solution with determined conductivity and subsequent weighing of the dry residue. page 10 HND-C110 K05/0422... -
Page 11: Salinity Measuring
The conductivity of aqueous solutions depends on its temperature. The temperature dependency is strongly dependent on the type of solution. The temperature compensation recalculates solutions’ conductivity to a consistent reference temperature. The most common reference temperature is 25 °C. HND-C110 K05/0422 page 11... -
Page 12: Device Configuration
Pressing “menu” and “store” at the same time for more than 2 seconds will reset the device to factory defaults. If no key is pressed for more than 2 minutes the configuration will be aborted. All changes will be discarded! page 12 HND-C110 K05/0422... - Page 13 Auto Power-Off: Selection of power-off delay 1…120 Power-off delay in minutes Device will automatically switch off as soon as this time has elapsed if no key is pressed/no interface communication takes place.
