5. Operating Principle
The KOBOLD manual pressure measuring devices HND-P210 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, for example.
The HND-P210 types also have a logger function, a peak value memory, or a
minimum/maximum alarm.
6. Electrical Connection
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.
Connecting/Changing Sensors
Do not use insuitable 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
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
see chapter 10 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.
In case of doubt, please return device to manufacturer for repair or maintenance.

8. Start of Operation
8.1 Connections
Connection for pressure sensors of the HND-P-family
Interface: Connection for el. isolated interface adapter
(see chapter 8.7 The Serial Interface)
The mains adapter socket is located at the left side of the
device.
8.2 Display
8.3 Basic Operation
When switching on the device and the logger function is not off the time of the
integrated clock will shortly be displayed. Furthermore the kind of measuring is
displayed (Slo/Fast/P.det, p.r.t 2.1) and “Corr”, if a Sensor with activated offset or
scale correction is connected.
After changing the battery the clock-setting menu is activated automatically
(‚CLOC‘). Check the clock and adjust, if necessary (see chapter 8.4
Configuration).
Tare Function: By pressing ´Tara´ (key 3) the display will be set to 0. All
measurings from then on will be displayed relatively to the set
tare value. When tara 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.

HND-P210 K08/0422 page 7
Max Memory: Pressing ´max´ (key 2) shows the maximum of the measured
values. Pressing it again hides them. 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 them. 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.
(only when logger = ‚off‘).
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 button 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).
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.
8.4 Configuration
To change device settings, press Menu (key 4) for 2 seconds. This will call the
configuration menu (main display: „SEt“).
Pressing key Menu changes between the menus, pressing (key 3) jumps to the
referring parameters, which can be selected with key (key 3).
The parameters can be changed with  (key 2) or  (key 5).
Pressing Menu again jumps back to the main configuration menu and saves the
settings.
Quit (key 6) finishes the configuration and returns to standard measuring
operation.

8.4.1 Different Kinds of Measuring: “rAtE-Slo, -P.dEt, -FASt”
Three different kinds of measuring pressure are supported. Two of them (P.dEt
and FASt) are working with high measuring frequency of more than 1000
measurings per second.
8.4.1.1 rAtE-Slo: Standard Measuring
Measuring rate 4Hz, averaging and filter functions are active.
Application: Measuring of slowly changing or static pressures, eg. measuring of
leakproofness, atmospheric pressure...
Highest accuracy, high noise immunity (EMI and unstable measuring signals),
low power consumption.
8.4.1.2 rAtE-P.dEt: Peak detection
Measuring rate >1000Hz, the value is displayed unfiltered.
Application with logger function: Measuring of short pressure peaks or fast
changing pressures with a resolution of <1ms. The cyclic logger function records
the arithmetic mean value, the highest and the lowest peak of the referring time
interval.
Attention: higher power consumption, measuring is sensitive to noise (EMI,..)
8.4.1.3 rAtE-FASt: Fast filtered measuring
Measuring rate >1000Hz, the value is filtered slightly (higher noise immunity than
P.dEt., small peaks will be filtered out), apart from that identical behaviour like
P.dEt.
8.4.2 Averaging Function
The averaging function concerns the display values (LCD and interface). It is
completely independent from the averaging of the logger function, please don’t
mix them up!
The averaging integrates the measuring values during a selectable period of time
and then calculates the average display value. It is independent from the selected
kind of measuring (slow, fast, peak detect). As long as not enough values are
collected (selected averaging time) to calculate a average value, the upper
display shows “----“, the lower display a ‘countdown‘.
During an active low-power-logging procedure the averring is always deactivated
Function of min/max-value memory during averaging:

HND-P210
page 10 HND-P210 K08/0422
 If averaging is activated and slow measuring is selected (rAtE-Slo), the min-
/max-value memory refers to the average display value.
 If averaging is activated and fast measuring is selected (rAtE-FASt or P.dEt) ,
the min-/max-value memory refers to the internal measured values (fast peaks
can be detected).
8.4.3 Power Off Time
If there won’t be pressed any key and no interface communication takes place for
the time of the power off time setting (P.Off), the device will be switched off
automatically to save battery power.
If P.oFF = oFF then the automatic switch off is deactivated.
8.4.4 Address
Up to 10 devices of the HND-P- handheld-family can be connected to a serial
interface at once (depending on interface converter). 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. See also chapter 8.7
The Serial Interface.
8.4.5 Alarm
There are three possible settings: Alarm off (AL. oFF), on with horn sound (AL. on),
on without sound (AL. no.So).
Following conditions will display an alarm, when the function is activated (on or
no.So):
 Value is below lower (AL. Lo) or above upper alarm rail (AL.Hi).
 Sensor error (Sens Erro)
 Low battery (bAt)
 Fe 7: System error (always with sound)
In case of an alarm and when polling the interface, the prio-flag is set in the
returned interface message.
8.4.6 Real Time Clock
The real time clock is used for the logger function: Recorded values are also
containing the point of time, when they were measured. Please check the settings
when necessary.
If the battery was replaced the refering menu ‚CLOC‘ will automatically be started.
