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.

7.6 Some Basics of Precision Temperature Measuring

 Probe Precision/Device Precision

The device is very precise (please refer to technical data). To be able to use
this high precision, the connected temperature probe has to be as precise as
possible, too. The following precision classes are available as a standard at
reasonable prices (Platinum resistor thermometers according to EN60751):

Class Error ranges
B ± (0.3 + 0.005 • |temperature|)
1/3 B (=1/3 DIN) ± (0.1 + 0.0017 |temperature|)
1/10 B (=1/10 DIN) ± (0.03 + 0,0005 • |temperature|)

A ± (0.15 + 0.002 • |temperature|)

Error over measuring range Error over range –50...150 °C

For applications demanding higher precision than given by this classes we
suggest to adjust the device to the used probe or to get a calibration certificate for
the device combined with the probe.
When demanding highest possible precision we suggest the usage of the
instrument HND-T205.

Attention: if an adjusted or calibrated probe is replaced, also the
adjustment or calibration certificate has to be renewed to maintain the
referring overall precision!

Be careful when buying third party temperature probes: Besides the
standard EN60751 there are some other obsolete or unusual standards on
the market. If such a probe has to be connected, the HND-T205 should be
used instead!

4-Wire-Measuring

When using resistance thermometers as the Pt100, a quite large measuring error
can be caused by inadequate cables and connections. Using 4wire measuring
avoids these kinds of errors mainly caused by unwanted resistances. It is
suggested to use suitable probes and extensions only. (For pin assignment

please refer to chapter 7.9 Probe pin assignment)

HND-T HND-T

HND-T105

page 10 HND-T105 K04/1016

Heat loss caused by probe construction:

Especially when measuring temperatures which deviate very much from the
ambient temperature, measuring errors often occur if the heat loss caused by the
probe is not considered. When measuring fluids therefore the probe should be
emerged sufficiently deep and be stirred continuously. When measuring gases
the probe should also emerge as deep as possible in the gas to be measured
(e.g. when measuring in channel/pipes) and the gas should flow around the probe

at sufficient flow.
Measuring Surface Temperature

If temperature of the surface of an object has to be measured, one should pay
attention especially when measuring hot (or very cold) surfaces, that the ambient
air cools (or heats) the surface. Additionally the object will be cooled (or heated)
by the probe or the probe can have a better heat flow to the ambient temperature
as to the objects surface. Therefore specially designed surface probes should
be used. The measuring precision depends mainly on he construction of the
probe and of the physics of the surface itself. If choosing a probe try to choose
one with low mass and heat flow from sensor to handle. Thermally conductive
paste can increase the precision in some cases.

Allowable temperature Range of Probes

Pt100 Sensors are defined over a wide temperature range. Depending on probe
materials and sort of sensor (e.g. hybrid sensors, wire wound resistors...) the
allowable temperature ranges have to be considered. Exceeding the ranges at
least causes a wrong measuring, it may even damage the probe permanently!
Often it also has to be considered, that the temperature range is just valid for the
probe tube, (plastic-) handles can’t stand the same high temperatures. Therefore
the tube length should be selected long enough, so that temperature keeps low at
the handle.

Self Heating

The measuring current of the instrument is just 0.3 mA. Because of this
comparably low current practically now self heating effect has to be considered,
even at air with low movement the self heating is <= 0.01 °C.

Cooling by Evaporation

When measuring air temperature the probe has to be dry. Otherwise the cold due
to the evaporation causes too low measurings.

7.7 Special Functions

7.7.1 Display Resolution

Standard setting: 'Auto', i.e. the device automatically switches over to the
optimum resolution between .01° and 0.01°.
If temperatures to be measured are near the switching threshold, a fixed
resolution may be better, e.g. for easy recording. In such a case please select the
optimum resolution manually.

7.7.2 Zero Displacement ('Offset')

A zero displacement can be carried out for the measured temperature:

temperature displayed = temperature measured - offset

Standard setting: 'off' = 0.0°, i.e. no zero displacement will be carried out.
Together with the scale correction (see below) this factor is mainly used to
compensate for sensor deviations. Unless the factor is set to 'off', the offset arrow
in the display shows an active zero displacement.

7.7.3 Scale Correction ('Scale')

The scale of the measuring can be influenced by this setting (factor is in %):

displayed temperature[°C] = measured temperature[°C] * (1+Scal/100)

respectively displayed temperature[°F] = (measured temperature [°F]-32 °F) *

(1+Scal/100) + 32 °F

Standard setting: 'off' =0.000, i.e. temperature is not corrected. Together with the
zero displacement (see above) this factor is mainly used to compensate for
sensor deviations.
Unless the factor is set to 'off', the Corr arrow in the display shows an active scale
correction.

7.7.4 Output

The output can be used as serial interface (for HND-Z031) or as analogue output
(0-1V). If none of both is needed, we suggest switching the output off, because
battery life then is extended.

7.7.4.1 Interface - Base Address ('Adr.')

By using an electrically isolated interface converter HND-Z031 or HND-Z032
(accessory) the device can be connected to a PC. In order to avoid transmission
errors, there are several security checks implemented (e.g. CRC).

The following standard software package is available for data transfer:

BUS-S20M Software for recording measurement data on a computer, for

instruments of the HND-series without logger function

Note: The measuring and range values read via interface are always in the
selected display unit (°C/°F)!

7.7.4.2 Analogue Output – Scaling with DAC.0 and DAC.1

With the DAC.0 and DAC.1 values the output can be rapidly scaled to Your
efforts.
Keep in mind not to connect low-resistive loads to the output, otherwise the
output value will be wrong and battery life is decreased. Loads up to ca 10kOhm
are uncritical.
If the display exceeds the value set by DAC.1, then the device will apply 1V to the
output.
If the display falls below the value set by DAC.0, then the device will apply 0V to
the output.
In case of an error (Err.1, Err.2, no sensor, etc.), the device will apply slightly
above 1V to the output.
