5. Operating Principle
The KOBOLD manual pressure measuring devices HND-P105 are highly precise,
compact pressure measuring devices that can be used universally. In conjunction
with the appropriate external pressure sensors, precise measurement results
over the entire measuring range can be achieved.
Various pressure sensors 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 pressure. All devices in this series allow for
minimum/maximum value memory, hold function, automatic self-shut-off, or zero
point offset entry for all connected pressure sensors.
6. Electrical Connection
6.1 Mains Operation With Power Supply
Warning: When using a power supply please note that operating
voltage has to be 10.5 to 12 VDC.
Do not apply overvoltage!! Cheap 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 power supply to the mains make sure that
the operating voltage stated at the power supply is identical to the
mains voltage.
6.1.1 Connecting/Changing Sensors
Do not use unsuitable sensors. Connecting other devices/sensors as specificated
may cause a damage to the instrument and device/sensor! Switch off device
before changing the sensor.
Connect sensor before switching on the device, otherwise the sensor may not be
detected correctly. When connecting the sensor 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 plug is entered correctly, it will slide in
smoothly. To disconnect sensor do not pull at the cable but at the plug (to open
locking mechanism).

7. Operation / Configuration / Adjustments
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 9 Technical Information.
2. Device and sensors have to be handled with care (don’t throw, hit, etc.).
Protect plugs and sockets from soiling.
3. 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.
4. 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
(e.g. short circuit from mains voltage to output voltage) this may
result in hazardous voltages at the device (e.g. at sensor socket or
interface).
5. 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
period of time.

7.3 Display
7.4 Basic Operation
When switching on the device displayed “Corr”, if a sensor with activated offset or
scale correction is connected.
Tare Function: By pressing `Tara`(key 3) the displays will be set to 0. All
measuring from then on will be displayed relatively to the set tare
values. When the tare function is activated, the arrow “Tara”
appears in the display. To deactivate tare function press `Tara`for
>2 seconds. Please note: Activating/deactivating tara clears
the max-&min-memories.
Max Memory: Pressing ´max´ (key 2) shows the maximum of the measured
values. Pressing it again hides it. To clear the max memory press
key ´max´ for >2 seconds.
Min Memory: Pressing ´min´ (key 5) shows the minimum of the measured
values. Pressing it again hides it. To clear the min memory press
key ´min´ for >2 seconds.
Hold Function:By pressing ´Store/Quit´ (key 6) the last measuring value will be
held in the secondary display. Pressing it again hides it.

Zero-Point Adjustment: If there is no pressure or zero-pressure (absolute)
applied to the pressure ports the device will display 0. If there is a
permanent deviation (and device is operated under steady
conditions), a permanent zero point adjustment can be carried
out. To carry out the adjustment press key 3 for approx. 5
seconds. (Auto Null will be displayed shortly). The adjustment is
done via the OFFSET-value of the sensor (referring configuration
menu). Please note: A zero-point adjustment can only be carried
out if the difference between the value on display is less than 500
digits!
To recall the manufacturer`s calibration press button 3 for approx.
15 seconds.
Note: If a zero-point adjustment was carried out, this will be
signalled by the short displaying of “Corr” when switching on the
device.
7.5 Configuration
To change device settings, press Menu (key 4) for 2 seconds. This will call the
configuration menu.
Pressing key Menu jumps between the parameters.
The parameters can be changed with (key 2) or (key 5).
Quit (key 6) finishes the configuration and returns to standard measuring
operation.
7.5.1 Unit: Choice Of The Display Unit
Choose the desired display unit, the referring unit is displayed by means of
a functional arrow in the display. The selection is permanently stored in the
sensor, therefore after reconnecting the sensor the unit will instantly
reappear. The choice depends on the used sensor.
7.5.2 Sea Level Correction For Absolute Pressure Sensors
The device displays the absolute pressure measured at the sensor. This is not
necessarily the same like the values given by weather stations! The weather
stations‘ values are pressure at sea level. Usually the sensor is placed above sea
level and therefore, if the value at sea level (zero) is to be measured, the
pressure loss resulting from the actual level above zero has to be considered!
To correct activate the „Sea-Level-Function“:
Select „on“ in the menu „SL“ with (key 2) or (key 5).
Jump to the next parameter „Alti“ by pressing Menu (key 4).
Then enter the altitude above sea level of the sensor‘s location in meters
and leave the configuration by pressing Quit (key 6)
If the sea level correction is active this will be shown by the functional arrow „SL“
in the display, the device now displays the absolute pressure at sea level (zero).

7.5.3 P.oFF: Auto Power Off Time
The device will be automatically switched off if no key is pressed/no
interface communication takes place for the time of the power off time.
The power off time can be set to values between 1 and 120 min. It can be
completely deactivated by setting the parameter to ‚P.oFF = oFF“.
7.5.4 Adr: Base Address of Interface
Up to 10 devices of the HND- handheld-family can be connected to a
serial interface at once (depending on interface converter, e.g. HND-P...: 5
devices). To get access to each device the base addresses of the devices
have to be different. For example choose 01 for the first, 11 for the second
device and so on.
7.5.5 OFFS: Adjusting Sensor Zero Displacement
A zero displacement can be carried out for the measured value:
value displayed = value 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. Input is in the display unit.
7.5.6 SCAL: Adjusting Sensor Scale
The scale of the measuring can be influenced by this setting (factor is in %):
displayed value = measured value*(1+Scal/100)
Standard setting: ´off´= 0.000, i.e. value is not corrected. Together with the zero
displacement (see above) this factor is mainly used to compensate for sensor
deviations.
7.6 Measuring Of Water Level – Display Unit [m]
(only for devices with ‚m‘ printed below the display)
When using a suitable waterproof pressure sensor the unit [m] for meters of
water can be set in the menu “Unit“. 10 m of water are roughly 1 bar over
pressure. Measurings can be made e.g. like described below :
With abs. pressure sensor (SL oFF!): Press ‚Tara‘ when sensor is at ambient
air and then bring sensor to the depth to be measured. The display shows now
the depth in [m].
With rel pressure sensor: bring tube connection for lower press. in contact to
ambient air by means of a tube (no water contact!) and bring the sensor with
its open press. connection for higher pressure to water depth to be measured
(display and is compensated for pressure changes in ambient air).

7.7 Calibration Services
Calibration certificates – DKD-certificates – other certificates:
If device should be certificied for its accuracy, it is the best solution to return it
with the referring sensors to the manufacturer.
Only the manufacturer is capable to do efficient recalibration if necessary to get
results of highest accuracy!
7.8 Pressure Connection To The Sensors
The device is designed to be connected to the sensors of the HND-PS...-series
without a new calibration being necessary. Therefore a great variety of
replaceable sensors of e.g. –1.999...2.500 mbar relative up to 0...400.0 bar
absolute pressure can be connected to the device (p.r.t. chapter 10.1 Pressure
sensors)
7.8.1 Relative Pressure Sensors
For measurements of over- or under pressure:
Connect plastic tube with internal dia of 4 mm to pressure port "B". Port "A" will
not be used!
Pressure sensors HND-PS01, -PS02 and –P03 allow for measurements of
under pressure up to the entire over pressure measuring range by re-plugging
the tube to pressure port "A". Please note that all values are displayed as
positive values. No minus sign will be shown. (Example for HND-PS02: For
tube connection "B" the measuring range covers -19.99 to 25.00 mbar. If you
replug to port "A" under pressure measurements down to -25.00 mbar could be
carried out with the display showing the value 25.00 (no minus sign).
For measurements of pressure differences:
Connect both plastic tubes with an internal dia of 4 mm to pressure port "B"
and "A"; make sure to apply higher pressure to port "B".
7.8.2 Absolute pressure sensors:
Connect plastic tube with an internal dia of 4 mm to pressure port "A". (Port "B" is
not used.)
7.8.3 Stainless steel pressure sensors:
For measurements of over-, under- or absolute pressure screw sensor to G1/4"
pressure terminal or plug plastic tube to a suitable adapter.
