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:
 Manual Humidity Precision Measuring Unit model: HND-F205

4. Regulation Use
Any use of the Manual Humidity Precision Measuring Unit, model: HND-F205,
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 manual measuring units HND-F205 were a completely new
development and offer decisive advantages in handling, user-friendliness, scope
of functions, and accuracy during measuring work.

6. Electrical Connection
6.1 Mains Operation
Attention: When using a power supply unit please note that
operating voltage has to be 10.5 to 12 VDC. Do not apply over
voltage!! Simple 12 V-power supplies often have excessive no-
load voltage. We, therefore, recommend using regulated voltage
power supplies. Trouble-free operation is guaranteed by our
power supply HND-Z002. Prior to connecting the plug power
supply with the mains supply make sure that the operating voltage
stated at the power supply is identical to the mains voltage.
 Treat device and probes carefully. Use only in accordance with above
specification (do not throw, hit against etc.). Protect plugs and sockets from
soiling.
 To disconnect sensor plug do not pull at the cable but at the plug.
 When connecting the probe, the plug will slide in smoothly if plug is entered
correctly.
 Selection of Output-Mode: The output can be used as serial interface or as
analogue output. This choice has to be done in the configuration menu.

7. Operation / Configuration / Adjustments
7.1 In General
7.1.1 Safety Instructions
This device has been designed and tested in accordance to 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 it.
1. Trouble-free operation and reliability of the device can only be guaranteed if it
is not subjected to any other climatic conditions than those stated under 9
Technical Information.
2. Transporting the device from a cold to a warm environment condensation may
result 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.
3. The circuitry has to be designed most carefully if the device should be
connected to other devices. 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.
Warning: Operating the device with a defective mains power supply
(e.g. short circuit from mains voltage to output voltage) may result
in hazardous voltages at the device (e.g. at sensor socket)
4. Whenever there may be 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

HND-F205
HND-F205 K06/0522 page 7
In case of doubt, please return device to manufacturer for repair or maintenance.
Warning: Do not use this product as safety or emergency stop
device, 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.
Risk of injury! The used measuring heads are very sharp, use
thoroughly during your measuring to eliminate a possible risk of
injury.
7.1.2 Disposal Notice
 Dispense exhausted batteries at destined gathering places.
 Send the device directly to us, if it should be disposed. We will dispose the
device appropriate and non-polluting.
7.1.3 Connections
1. Output: Operation as interface:
Connect to optically isolated interface adapter
(accessory: HND-Z031/-Z032)
Operation as analogue output:
Connection via suitable cable.
Attention: The output mode has to be configured
and influences battery life!
2. Sensor-connection: BNC
3. Temperature-probe-connection: Thermocouple type K
(NiCr-Ni) for temperature-compensation with an external
temperature-probe
4. The mains socket is located at the left side of the
instrument.

7.2 Device Configuration
Note: Some menu items will be shown depending on the actual
device configuration (e.g. there are some items disabled when the
logger contains data). Please note the hints by the menu items.
For configuration of the device press "Menu"-key (key 4) for 2 seconds, the main
menu will be shown (main display: “SEt”). Choose the desired menu branch by
pressing the "Menu"-key (key 4). By pressing “” (key 3) the referring parameters
can be chosen. The referring values are changed by pressing the keys "" (key
2) or "" (key 5) (Choice of parameter: “”). Pressing “Menu” (key 4) again will
jump back to the main menu selection and stores the settings.
Use key " Store/" (key 6) to leave configuration.
