2. Note
Please read these operating instructions before unpacking and putting the unit
into operation. Follow the instructions precisely as described herein.
The instruction manuals on our website www.kobold.com are always for currently
manufactured version of our products. Due to technical changes, the instruction
manuals available online may not always correspond to the product version you
have purchased. If you need an instruction manual that corresponds to the
purchased product version, you can request it from us free of charge by email
([email protected]) in PDF format, specifying the relevant invoice number and
serial number. If you wish, the operating instructions can also be sent to you by
post in paper form against an applicable postage fee.
The devices are only to be used, maintained and serviced by persons familiar
with these operating instructions and in accordance with local regulations
applying to Health & Safety and prevention of accidents.
When used in machines, the measuring unit should be used only when the
machines fulfil the EC-machine guidelines.
3. Instrument Inspection
Instruments are inspected before shipping and sent out in perfect condition.
Should damage to a device be visible, we recommend a thorough inspection of
the delivery packaging. In case of damage, please inform your parcel service /
forwarding agent immediately, since they are responsible for damages during
transit.
Scope of delivery:
The standard delivery includes:
pH-, Redox- and Temperature Portable Measuring Instruments
model: HND-R106
4. Regulation Use
Any use of the pH-, Redox- and Temperature Portable Measuring Instruments,
model: HND-R106, which exceeds the manufacturer’s specification, may
invalidate its warranty. Therefore, any resulting damage is not the responsibility of
the manufacturer. The user assumes all risk for such usage.

5. Operating Principle
The KOBOLD hand-held pH, Redox and temperature measuring instruments of
the HND-R106 model are compact and universally applicable measuring units for
electrodes with BNC plug connection. An extensive selection of electrodes makes
it possible to use the HND-R106 in almost all application areas. The KOBOLD
HND-R105 measuring unit offers functions like minimum/maximum value
memory, hold function, auto off function and automatic temperature
compensation. In addition to pH, Redox and temperature measurement, the
device can display the rH value. This is calculated from the measured Redox-
value and the previously measured or manually entered pH-value.
6. Electrical Connection and Maintenance Advice
Treat device and sensor carefully. Use only in accordance with above
specification (do not throw, hit against etc.). Protect plug and socket from soiling.
6.1 Mains operation
Attention: When using a power supply device please note that
operating voltage has to be 10.5 to 12 VDC. Do not apply
overvoltage!! Cheap 12 V-power supply devices often have
excessive no-load voltage. We, therefore, recommend using
regulated voltage power supply devices. Trouble-free operation is
guaranteed by our power supply HND-Z002. Prior to connecting
the plug power supply device with the mains supply make sure
that the operating voltage stated at the power supply device is
identical to the mains voltage.
6.2 When to replace battery
If and ´bAt´ are shown in the lower display the battery has been used up and
needs to be replaced. The device will, however, operate correctly for a certain
time. If ´bAt´ is shown in the upper display the voltage is too low to operate the
device; the battery has been completely used up.
Please note: The battery has to be taken out, when storing
device above 50 °C. We recommend taking out battery if device
is not used for a longer period of time.

6.3 Temperature probe
When connecting the temperature probe the connector may not lock to the jack
correctly.
In such a case hold the connector not at the case but at the buckling protection of
the cable during the plug in. Don't connect electrode canted! If plug is entered
correctly, it will slide in smoothly. To disconnect temperature probe do not pull at
the cable but at the plug.
If plug is entered incorrectly the connecting pins of the plug can be damaged. =>
Plug can no longer be used and connecting cable needs to be replaced.
6.4 Damaged electrode
Display values for damaged electrode cable or if no pH or redox-electrode has
been connected:
If no electrode is connected or the connection cable is damaged the display will
nevertheless show mV, pH or rH values.
Please note that these values can never be correct measuring results!
7. Safety Requirements
This device has been designed and tested in accordance with the safety
regulations for electronic devices. However, its trouble-free operation and
reliability cannot be guaranteed unless the standard safety measures and special
safety advises given in this manual will be adhered to when using the device.
1. Trouble-free operation and reliability of the device can only be guaranteed if
the device is not subjected to any other climatic conditions than those stated
under chapter Technical Data.
If the device is transported from a cold to a warm environment condensation
may cause in a failure of the function. In such a case make sure the device
temperature has adjusted to the ambient temperature before trying a new
start-up.
2. If device is to be connected to other devices (e.g. via serial interface) the
circuitry has to be designed most carefully. Internal connection in third party
devices (e.g. connection GND and earth) may result in not-permissible
voltages impairing or destroying the device or another device connected.
HND-R106
HND-R106 K09/0422 page 7
Warning: If device is operated with a defective mains power supply
(short circuit from mains voltage to output voltage) this may result
in hazardous voltages at the device (e.g. sensor socket, serial
interface).
3. If there is a risk whatsoever involved in running it, the device has to be
switched off immediately and to be marked accordingly to avoid re-starting.
Operator safety may be a risk if:
• there is visible damage to the device
• the device is not working as specified
• the device has been stored under unsuitable conditions for a longer time.
In case of doubt, please return device to manufacturer for repair or
maintenance.
Warning: Do not use these products as safety or emergency stop
devices or in any other application where failure of the product
could result in personal injury or material damage. Failure to
comply with these instructions could result in death or serious
injury and material damage.
