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 EWG-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:

• Handheld Digital Pessure Meter with internal pressure sensor

model: HND-P239

• Operating Instructions

4. Regulation Use

Any use of the Handheld Digital Pressure Meter, model: HND-P239, 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 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).

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 HND­Z002. 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.

8. Operation

When switching on the device and the logger function is not off the time of the

integrated clock will shortly be displayed.
After changing the battery the clock-setting menu is activated automatically
(‚CLOC‘). Check the clock and adjust, if necessary (see chapter 9. Configuration).

On-/Off-Switch
Tara: Calling of tara function, zero point adjustment
min/max: Showing the min- resp. max-memory in sec.

display
Store/Quit: Calling of hold function resp. calling of logger
functions

(please refer to chapter 10. “Operation Of Logger”)

Set/Menu: Calling of configuration

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. (only when logger
= ‚off‘).

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.

Note: Activating/deactivating tara clears the max- & min-memories.
