2. Note

Please read these operating instructions before unpacking and putting the unit

into operation. Follow the instructions precisely as described herein.

The instruction manuals on our website www.kobold.com are always for currently

manufactured version of our products. Due to technical changes, the instruction

manuals available online may not always correspond to the product version you

have purchased. If you need an instruction manual that corresponds to the

purchased product version, you can request it from us free of charge by email

([email protected]) in PDF format, specifying the relevant invoice number and

serial number. If you wish, the operating instructions can also be sent to you by

post in paper form against an applicable postage fee.

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 EC-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:

 Manual Pressure Measuring Devices with External and Integrated Pressure

Sensors model: HND-P231/HND-P233/HND-P236/HND-P239

4. Regulation Use

Any use of the Manual Pressure Measuring Devices with External and Integrated

Pressure Sensors, 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 highly precise KOBOLD hand-held pressure measuring devices HND-P231/-

P233/-P236 are measuring devices with integrated pressure sensors. They have

two pressure measurement inputs on the top of the housing, which are connected

to the measuring points by means of stable metal connections and plastic hoses

that are available as accessories. Numerous measuring ranges in the

overpressure and under pressure range are available for various measurement

tasks, such as differential pressure measurement. In addition to pressure display,

these first-rate, compact, universally applicable measuring units offer additional

functions such as minimum/maximum value memory, a hold function, tare

function, automatic self-shut-off, or zero point offset. The devices with an

expanded spectrum of functions also have a logger function, a peak value

memory, minimum/maximum alarm, an adjustable measuring cycle, and

averaging.

The KOBOLD hand-held pressure measuring devices 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 KOBOLD HND-P239

devices also offer additional functions like the logger function, peak value

memory, minimum/maximum alarm, an adjustable measuring cycle, and

averaging.

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.

7. Operation

7.1 General

7.1.1 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 Technical Information.

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.

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.

2. When connecting the device to other devices the connection has to be

designed most thoroughly as internal connections in third-party devices (e.g.

connection GND with protective earth) may lead to undesired voltage

potentials that can lead to malfunctions or destroying of the device and the

connected devices.

3. Do not use these products as safety or emergency stop devices or in any

other application where failure of the product could result in personal injury or

material damage. Failure to comply with these instructions could result in

death or serious injury and material damage.

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).

7.2 Connections

Connection for pressure tubes:

„+“ = higher pressure, „-“ = lower pressure

Interface: Connection for el. isolated interface adapter

(p.r.t. chapter 8.5 Serial Interface)

The mains adapter socket is located at the left side of the device.

7.3 Display

7.4 Basic Operation

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

memories.

HND-P231/-233/-236/-239

HND-P231/-233/-236/-239 K05/0422 page 7

1) 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).

To recall the manufacturer’s calibration press button 3 for approx. 15 seconds.

Please Note: A zero-point adjustment can only be carried out if

the difference between the value on display is less than 500

digits!

If a zero point adjustment was carried out the display shows

”Corr” after a restart .

7.5 Operation

After turning on, if the logger function is not off, the time of the integrated clock

will shortly be displayed. If a zero point adjustment was carried out the display

shows shortly „nuLL Corr“.

After changing the battery the clock-setting menu is activated automatically

(‚CLOC‘). Check the clock and adjust, if necessary (p.r.t. chapter 7.7).

7.6 Pop-up clip

Handling:

 Pull at label “open” in order to swing open the pop-up clip.

 Pull at label “open” again to swing open the pop-up clip further.

Function:

 The device with a closed pop-up clip can be plainly laid onto a table or

attached to a belt, etc.

 The device with pop-up clip at position 90° can be set up on a table, etc.

 The device with pop-up clip at position 180° can be suspended from a

screw or the magnetic holder.

7.7 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 menues, pressing (key 3) jumps to

the refering 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.
