1. Foreword
Thank you for the confidence that you have shown in Kobold by purcha­sing the PDC digital manometer.
Like all other Kobold products, PDC digital manometers are a combi­nation of customer requirements, state-of-the-art technology, modern manufacturing and stringent quality control.
The Kobold digital manometer described in the operating instructions is designed and produced in line with the most recent developments. All components are subject to the strictest quality criteria during production.
These operating instructions have been compiled with care. However, it is impossible to take every possible usage case into consideration. For this reason, if you feel that instructions for your particular usage case are missing, please contact Kobold, and we would be pleased to provide assistance. Please observe the relevant national safety regulations during the installation, start-up and operation of this temperature switch (e.g.: VDE 0100).
Scope These instructions apply to the PDC series of digital manometers.
Distinctions are drawn between the PDC-1 and PDC-2 models in the individual sections. The state of technology at the time of delivery always applies. Kobold reserve the right to make technical changes without notice.

Safety instructions and warnings
Please read these instructions before installing and starting up the digital manometer. Failure to follow the instructions will make all guarantee, warranty and compensation claims null and void.
• Please ensure that the digital manometer is suitable for your application.
• Please check that the materials that come into contact with the medium are compatible with the media that are going to be measured.
• Perfect function and operating reliability of the device can only be guaranteed for the values specified in the technical data sheet.
• Only qualified persons are permitted to install the equipment and make the electrical connection, and the correct tools must always be used.
• Damaged devices must not be started up. If damage occurs during operation, suitable measures must be taken to prevent persons or property from being put at risk by the damaged digital manometer.
• The manometer must only be repaired by
Kobold. The accepted technical regulations and all national regulations must always be observed and complied with.
Warning When screw-fitting the gauges the force required for this must not be

Exclusion of liability
Kobold guarantees that the digital manometer is in perfect working condition when it is delivered. The basis consists of the technical data in the data sheet and these operating instructions. Liability cannot be accepted for the suitability of the digital mano­meter. Usage for any other purpose than the ones that are mentioned in „Correct purpose of use“ is not permitted.
Claims for compensation will only be entertained by Kobold in the event of intent or gross negligence. Responsibility for damage to equipment, systems or the surroundings of the digital manometer will not be accepted. No liability is accepted for damage caused by incorrect operation. The haulage contractor is responsible for damage that occurs in transit.
2. Digital manometer description
The digital manometer is available in two versions PDC-1 and PDC-2 for most varied areas of use.
The digital manometer offers the user numerous measuring units (bar, psi and MPa). Additional functions such as MIN/MAX memory, tare adjustment plus bar graph with trailing pointer function round off the digital manometer’s profile. The programmable parameters are adjusted by means of user-friendly keys on the front.

Correct purpose of use
The equipment is only authorised for proper use for its correct pur­pose. Failure to do this will invalidate all warranties and release the manufacturer from all responsibility!
The equipment is constructed in compliance with IP65 and should be protected from excessive amounts of water and dust. The equipment must be installed so that it is protected from external damage. It must be ensured that the manometer is correctly installed and has the relevant IP protection. The limits specified in the data sheet must be complied with.
3. Commissioning
Installation
The digital manometer must be connected to the pressure tapping point in a suitable manner using your own tools. In this case there must be no occurrence of pressure which exceed the device’s maximum pressure values. Pressures which exceed the digital manometer’s maximum range can lead to permanent damage to the measuring device.
Voltage supply
The digital manometer is operated with 2 Mignon AA batteries. A flashing battery symbol appears on the display screen if the batte­ry charge is low and the batteries should then be replaced as soon as possible. Open the battery compartment lid on the back of the digital manometer. Replace the batteries with 2 new Mignon cells. Replace the battery compartment lid.

Key Function/Action
- switches the device on
- switches the device off (only display mode)
- changes to programming mode if pressed for longer than 3 secs
- Display indicated max. value as long as key is pressed
- Display indicates min. value as long as key is pressed
- Resets max. value to “ 0 “
- Resets min. value to “ 0 “

Min/Max Memory
The min/max memory is updated with the current measured value in every measuring cycle. The min. value is displayed by pressing the min. key. The max. value is displayed by pressing the max. key. Pressing and holding the appropriate key (min. or max.) and quickly pressing the menu key at the same time resets the device to the current measured value.
Bar Graph with Trailing Pointer Function
The integrated bar graph display with trailing pointer function addi­tionally indicated on the display shows the trend in current working pressure directly regardless of the digital display. With the help of the trailing pointer function, the max. stored value is also indicated in the bar graph display in addition to the digital display in the form of a bar segment. This bar segment is also updated to the current measure value when the min./max. value is reset.

Tare Function PDC-2
In this mode the positive deviation of the measured value from the tared value (max. 20% of the measuring range) is constantly indica
­ted by the main display. The untared pressure value is always shown on the bar graph display. Thus the digital manometer’s actual wor­king load can be read off even if the tare function is active. When the tare function is active, a function indicator appears on the display. There are 2 possible ways of activating this mode:
1) Select the tare function and set the value to be tared using the keys . When set, the measured value to be tared is backed up as tare. The main display and the auxiliary display then show the value “0000” in the unpressurised state. Example: If a value to be tared is set as 2 bar, the main display indicates 0 bar in the unpressurised state.
2) Load the digital manometer with the pressure to be tared. The current measured value appears in the main display field of the main display. Select the tare function and then operate both keys simultaneously . The current measured value will be backed up as tare. The main display and the auxiliary display are set to (0000).
Setting the tare value to (0000) resets the tare function in both models.
