5. Operating Principle
The KOBOLD Handheld Digital Pressure Meters HND-P239 have an integrated
pressure sensor for absolute pressure measurement. The measuring device is
connected to the measuring point by means of a stable, metal connection on the
top of the housing and an optional plastic hose. This device design offers the
possibility of also displaying the barometric air pressure in relation to sea level
»zero«. In this case, air pressure is corrected by entering the height above
»zero« in meters. Naturally, these devices also have the minimum/maximum
value memory, a hold function, a tare function, automatic self-shut-off function,
and zero point adjustment. The HND-P239 devices also offer additional functions
like the logger function, peak value memory, minimum/maximum alarm, an
adjustable measuring cycle, and averaging.
6. 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 "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 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).

HND-P239
HND-P239 K01/0307 page 5
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
period of time.
In case of doubt, please return device to manufacturer for repair or maintenance.
7. Electrical Connection
By operation with external power supply:
When using a power supply please note that operating voltage has to be 10.5 to
12 VDC. Do not apply overvoltage!!! Cheap 12V-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.

9.1 Different Kinds Of Measuring: „rAtE-Slo, -P.dEt, -FASt“
Three different kinds of measuring pressure are supported. Two of them are
working with high measuring frequency of more than 100 measurings per second.
If one of them was chosen in the configuration (see above), this will be displayed
in the secondary display: „P.dEt“ or „FASt“.
9.1.1 rAtE-Slo: Standard Measuring
Measuring rate 4Hz, averaging and filter functions are active.
Application: Measuring of slowly changing or static pressures, e.g. measuring of
leak proofness, atmospheric pressure...
Highest accuracy, high noise immunity (EMI and unstable measuring signals),
low power consumption.
9.1.2 rAtE-P.dEt: Peak detection
Measuring rate >100Hz, the value is displayed unfiltered.
Application with logger function: Measuring of short pressure peaks or fast
changing pressures with a resolution of <10ms. 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,..).
9.1.3 rAtE-FASt: Fast filtered measuring
Measuring rate >100Hz, 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.
9.2 Sea Level Correction
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 giving the 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 sea level has to be
considered! To correct the measuring display activate the „Sea-Level-Function“
(SL, please refer to chapter 9. “Configuration”). Then enter the altitude above sea
level of the sensor‘s location in meters (Alti, please refer to chapter 9.
Configuration). When activated, the display shows the SL-arrow and the device
displays the pressure value at sea level.

HND-P239
HND-P239 K01/0307 page 9
9.3 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 averaging is always
deactivated.
Function of min/max-value memory during averaging:
• 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).
9.4 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.
9.5 Address
Up to 10 devices of the GMH3xxx- handheld-family can be connected to a serial
interface at once (depending on interface converter, e.g. GRS3105: 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.
See also chapter 11. “The Serial Interface”.
9.6 Alarm
There are three possible settings: Alarm off (AL. oFF), on with horn sound (AL.
on), on without horn 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.

9.7 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 referring menu ‚CLOC‘ will automatically be
started.
10. Operation Of Logger
The device supports two different logger functions:
„Func-Stor“:
each time when „store“ (key 6) is pressed a measurement will be recorded.
„Func-CYCL“:
measurements will automatically be recorded each interval, which was set in the
logger menu ‚CYCL‘ until the logger will be stopped or the logger memory is full.
The recording is started by pressing „Store“ 2 seconds.
The logger records 3 measurement results each time:
Current or mean value (depending on logger setting, see below), min peak and
max peak.
Min and max peak are the minimum resp. the maximum of the measured values
since the last recording.
Using them allows f.e. analysis of fluctuating pressures.
For the evaluation of the data the software HND-Z034 has to be used. The
software also allows easy configuration and starting of the logger.
When the logger is activated (Func Stor or Func CYCL) the hold function is no
more available, the key 6 is solely used for the operation of the logger functions.
10.1„Func-Stor“: Storing Single Measurements
Each time when „store“ (key 6) is pressed a measurement and its time stamp will
be recorded.
The recorded data can be viewed either in the display (when calling the
configuration an additional menu „REAd LoGG“ is displayed, see below) or by
means of the interface and a PC with GSOFT3050-software.
Max. number of measurings: 99
A measuring contains:
- current measuring value at the time of recording
- min peak, max peak since the last recording
- - time and date of the recording

HND-P239
HND-P239 K01/0307 page 11
After each recording „St. XX“ will be displayed for a short time. XX represents the
number of the recording.
If logger memory contains recordings already:
When „Store“ is pressed for 2 seconds, the choice for clearing the logger memory
will be displayed:
The selection can be made by “5“ (key 2) and “6“ (key 5). "Quit" (key 6) enters
the choice.
If the logger memory is full, the display will show:
Viewing Recorded Measurements
Within the „LoGG Stor“ function the measurements can be viewed directly in the
display not only by means of a computer (like at „Func CYCL“): press 2 seconds
„Set“ (key 4): The first menu displayed now is „rEAd LoGG“ (read logger data).
After pressing “4“ (key 3) the measurement recorded last will be displayed,
changing between the different values referring to the measurement also is done
by pressing “4“.
Changing the measurement is done by pressing the keys “5“ or “6“.
10.2„Func-CYCL“: Automatic Recording With Selectable
Logger-Cycle-Time
The Logger-Cycle-Time is settable (please refer to Configuration). For example
„CYCL“ = 60: A measuring is recorded after each 60 seconds.
When the slow measurement "rAtE-Slo" is chosen, additionally a low power
function is available: „Lo.Po“.
If „Lo.Po“ is on, the device only will take a measurement at the point of time of the
recording. In between the recordings the measuring shuts down. This decreases
the power consumption enormously and therefore is recommended e.g. for long
time recordings where no mains adapter is available.
Max. number of measurings: 9999
Cycle time: 1...3600 seconds (=1h), selectable in the configuration
A measurement comprises of:
by slow measurements (rAtE Slo):
• current measuring value at the time of recording
• min peak, max peak since the last recording
by fast measurements (rAtE FASt,P.dEt)

• arithmetic mean value since the last recording
• min peak, max peak since the last recording
Starting a recording:
By pressing "Store" (key 6) for 2 seconds the recording will be initiated. After that
the display shows ‘St.XXXX‘ for a short time whenever a measuring is recorded.
XXXX is the number of the measuring 1..9999.
If the logger memory is full, the display will show: The recording
automatically will be stopped.
If Low-Power-Logger-Function „Lo.Po = on“ the device switches itself off as soon
as the memory gets filled.
Stopping the recording manually:
By pressing "Store" (key 6) the recording can be stopped manually. Then the
following choice appears:
The selection can be made by “5“ (key 2) and “6“ (key 5). "Quit" (key 6) enters
the choice.
Note: If you try to switch off the instrument in the cyclic recording
operation You will be asked once again if the recording is to be
stopped. The device can only be switched off after the recording
has been stopped!
The Auto-Power-Off-function is deactivated during recording!
Clear Recordings:
When „Store“ is pressed for 2 seconds, the choice for clearing the logger memory
will be displayed:
The selection can be made by “5“ (key 2) and “6“ (key 5). "Quit" (key 6) enters
the choice.
