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-F215
4. Regulation Use
Any use of the Manual Humidity Precision Measuring Unit, model: HND-F215,
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 HND-F215 manual measuring unit allows for the measurement of
gas humidity and gas temperature or the gas respectively water flow. Appropriate
probes are available for both measuring applications (for more technical data, see
subsequent pages). The device offers extensive functions, a high degree of
accuracy, and decisive advantages in operation in order to support the user in
determining the various measured quantities.
In addition to the standard basic functions like minimum/maximum value memory,
hold function, dew-point calculation, or a calibration function for humidity
measurement, the improved device design KOBOLD HND-F215 has a
minimum/maximum alarm, adjustable alarm, a real-time clock, and logger
function.
6. Electrical Connection
6.1 Mains operation
When using a power supply device please note that operating
voltage has to be 10.5 to 12 VDC. Do not apply over-voltage!! 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.
 Treat device and sensor carefully. Use only in accordance with above
specification. (do not throw, hit against etc.). Protect plug and socket from
soiling. Only use for the HND specified sensors. Connecting the instrument to
others, may damaged the instrument and the probe.
 Switch off instrument to change sensors.
 When connecting the probe, the connector may not lock correctly. In such
case take the plug not at the casing but at the buckling protection at the end of
the plug. If the plug is entered correctly, it will slide in smoothly.
 To disconnect sensor/probe, the interface or the power supply devices do not
pull at the cable but at the plug.

7. Operation
7.1 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 9. Technical Information.
2. 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.
3. 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.
Warning: If device is operated with a defective mains power supply
(short circuit from mains voltage to output voltage) this ma result in
hazardous voltages at the device (e.g. sensor socket at interface).
4. 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 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 serious injury and
material damage.
