Use of the product in accordance with the intended use DG-10-S, DG-10-E:
Use the digital gauge for reading pressure from the digital display.
1. Important details for your information
Read these operating instructions before installing and starting the digital gauge. Keep the
operating instructions in a place that is accessible to all users at any time.
The following installation and operating instructions have been compiled by us with great care
but it is not feasible to take all possible applications into consideration. These installation and
operation instructions should meet the needs of most pressure measurement applications. If
questions remain regarding a specific application, you can obtain further information:
Via our Internet address www.wika.de / www.wika.com
The product data sheet is designated as PE 81.66
Contact WIKA for additional technical support (+49) 9372 / 132-295
With special model number, e.g. DG-10000, please note specifications in the delivery note.
If the serial number gets illegible (e.g. by mechanical damage or repainting), the retraceability
of the instrument is not possible any more.
WIKA digital gauge are carefully designed and manufactured using state-of-the-art technology. Every component undergoes strict quality and environmental inspection before
assembly and each instrument is fully tested prior to shipment. Our environmental management system is certified to DIN EN ISO 14001.
Knowledge required
Install and start the digital gauge only if you are familiar with the relevant regulations
and directives of your country and if you have the qualification required. You have to be
acquainted with the rules and regulations on measurement and control technology and electric circuits, since this digital gauge is „electrical equipment“ as defined by EN 50178. Depending on the operating conditions of your application you have to have the corresponding
knowledge, e.g. of aggressive media.
2. A quick overview for you

The pressure prevailing within the application is transformed into a standardised electrical
signal through the deflection of the diaphragm, which acts on the sensor element with the
power supply fed to the digital gauge. This electric signal changes in proportion to the pressure and is correspondingly displayed.

Notice, important information, malfunction.
The product complies with
the applicable European
directives.
Potential danger of life or
of severe injuries due to
catapulting parts.
Potential danger of burns
due to hot surfaces.
5. For your safety
Select the appropriate digital gauge with regard to scale range, performance
and specific measurement conditions prior to installing and starting the
instrument.
Observe the relevant national regulations (e.g.: EN 50178) and observe
the applicable standards and directives for special applications (e.g. with
dangerous media such as acetylene, flammable gases or liquids and toxic
gases or liquids and with refrigeration plants or compressors). If you do not
observe the appropriate regulations, serious injuries and/or damage
can occur!
Open pressure connections only after the system is without pressure!
Please make sure that the digital gauge is only used within the overload threshold limit all
the time!
Observe the ambient and working conditions outlined in section 7 „Technical data”.
Observe the technical data for the use of the digital gauge in connection with aggressive /
corrosive media and for the avoidance of mechanical hazards.
Ensure that the digital gauge is only operated in accordance with the provisions i.e. as
described in the following instructions.
Do not interfere with or change the digital gauge in any other way than described in
these operating instructions.
Remove the digital gauge from service and mark it to prevent it from being used again
accidentally, if it becomes damaged or unsafe for operation
Take precautions with regard to remaining media in removed digital gauge.
Remaining media in the pressure port may be hazardous or toxic!
Have repairs performed by the manufacturer only.
6. Packaging
Has everything been supplied?
Check the scope of supply:
Completely assembled digital gauge.
Inspect the digital gauge for possible damage during transportation. Should there be
any obvious damage, inform the transport company and WIKA without delay.
Keep the packaging, as it offers optimal protection during transportation (e.g.
changing installation location, shipment for repair).
Ensure that the pressure connection thread and the digital display will not be
damaged.

For Model DG-10 you have to provide for a sealing element; exceptions are instruments with self-sealing threads (e.g. NPT thread).
Please refer to our data sheet “Pressure gauge sealing washers AC 09.08” in WIKA’s
product catalog Pressure and Temperature Measurement or our website
www.wika.de for details about sealing washers.
When mounting the instrument, ensure that the sealing faces of the instrument and
the measuring point are clean and undamaged.
Screw in or unscrew the instrument only via the flats using a suitable tool. The
appropriate torque depends on the dimension of the pressure connection and on
the sealing element used (form/material). Do not use the case as working surface for
screwing in or unscrewing the instrument.
When screwing the digital gauge in, ensure that the threads are not jammed.
For tapped holes and welding sockets please see Technical Information IN 00.14 for
download at www.wika.de -Service
Operate the digital gauge with 2 Mignon batteries AA.
If the charge state of the batteries is low, a flashing battery symbol will appear on the
display. In this case, replace the batteries.
Open the battery compartment cover on the back of the digital gauge.
Replace the batteries with 2 new Mignon cells. Close the cover of the battery
compartment.

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.
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 -key.
The max. value is displayed by pressing the -key.
Pressing and holding the appropriate key (min. or max.) and quickly pressing the menu key at

Tare Function DG-10-E
In this mode the positive deviation of the measured value from the tared value (max. 20% of
the measuring range) is constantly indicated by the main display. The untared pressure value
is always shown on the bar graph display. Thus the digital gauge’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 gauge 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.

Functional test
Open pressure connections only after the system is without pressure!
Observe the ambient and working conditions outlined in section 7
„Technical data.
Please make sure that the digital gauge is only used within the overload
threshold limit at all times!
When touching the digital gauge, keep in mind that the surfaces of the
instrument components might get hot during operation.
When designing your plant, take into account that the stated values (e.g.burst
pressure, over pressure safety) apply depending on the material, thread and sealing
element used.
The displayed measure value must be proportional to the pressure. If not, this might
point to a damage of the sensor diaphragm. In that case refer to chapter 9 „Troubleshooting“.
