2. Note

Please read these operating instructions before unpacking and putting the unit
into operation. Follow the instructions precisely as described herein.
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:

 Double/Differential Second Portable Thermometer, model: HND-T105
 Operating Instructions

4. Regulation Use

Any use of the Double/Differential Second Portable Thermometer, model:
HND-T105, 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 temperature measuring units HND-T105 are highly
precise, compact thermometers for PT100 4-wire-probes that can be used
universally. The high degree of accuracy of these housings makes them
extremely well suited for all calibration tasks. In conjunction with the appropriate
temperature probes, precise measurement results over the entire measuring
range can be achieved. Various probes are available for a multitude of measuring
tasks and special applications. The respective measurement task determines
which combination is selected. Naturally, these first-rate KOBOLD-measuring
units can display more than just the temperature values. All housings in this
series allow for minimum/maximum value memory, hold function, automatic self­shut-off, and zero point/increase entry, for example.

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
overvoltage!! Simple 12V-power supplies often have excessive no­load 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.

6.2 Battery Operation

The battery has been used up and needs to be replaced, if „bAt“ is shown in

lower display.
The device however, will continue operating correctly for a certain time.
The battery has been completely used up, if ´bAt´ is shown in the upper display.
The battery has to be taken out, when storing device above 50 °C.

Hint: We recommend removing the battery if device is not used for
a longer period of time!

7. Operation / Configuration / Adjustments

7.1 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
8 Technical Information.

2. By 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’s safety may be a affected 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 death or

serious injury and material damage.

7.2 Connections

1 Output: Operation as interface: Connect to optically

isolated interface adapter
