2. Safety

WARNING!

Before installation, commissioning and operation, ensure that the appropriate digital

pressure gauge has been selected in terms of measuring range, design and specic

measuring conditions.

Non-observance can result in serious injury and/or damage to the equipment.

WARNING!

■

Open the connections only after the system has been depressurised.

■

Observe the working conditions in accordance with chapter 3 "Specications".

■

Always operate the digital pressure gauge within the overpressure limit.

Further important safety instructions can be found in the individual chapters of these

operating instructions.

2.1 Intended use

The digital pressure gauge acts as the display for the applied pressure. The pressure value is displayed

via a digital indicator.

The instrument has been designed and built solely for the intended use described here, and may only

be used accordingly.

The technical specications contained in these operating instructions must be observed. Improper

handling or operation of the digital pressure gauge outside of its technical specications requires the

digital pressure gauge to be taken out of service immediately and inspected by an authorised WIKA

service engineer.

The manufacturer shall not be liable for claims of any type based on operation contrary to the intended

use.

2. Safety

2.2 Personnel qualication

WARNING!

Risk of injury should qualication be insucient!

Improper handling can result in considerable injury and damage to equipment.

The activities described in these operating instructions may only be carried out by skilled

personnel who have the qualications described below.

Skilled personnel

Skilled personnel are understood to be personnel who, based on their technical training, knowledge

of measurement and control technology and on their experience and knowledge of country-specic

regulations, current standards and directives, are capable of carrying out the work described and

independently recognising potential hazards.

Special operating conditions require further appropriate knowledge, e.g. of aggressive media.

2.3 Special hazards

WARNING!

For hazardous media such as oxygen, acetylene, ammable or toxic gases or liquids,

and refrigeration plants, compressors, etc., in addition to all standard regulations, the

appropriate existing codes or regulations must also be followed.

WARNING!

Residual media in dismounted digital pressure gauges can result in a risk to persons, the

environment and equipment.

Take sucient precautionary measures.

4. Design and function / 5. Transport, packaging and storage

4. Design and function

4.1 Description

The prevailing pressure is measured at the sensor element through the deformation of a diaphragm. By

supplying power, this deformation of the diaphragm is converted into an electrical signal. This signal is

displayed via a digital indicator.

4.2 Scope of delivery

Cross-check scope of delivery with delivery note.

5. Transport, packaging and storage

5.1 Transport

Check the digital pressure gauge for any damage that may have been caused by transport.

Obvious damage must be reported immediately.

5.2 Packaging

Do not remove packaging until just before mounting.

Keep the packaging as it will provide optimum protection during transport (e.g. change in installation

site, sending for repair).

5.3 Storage

Permissible conditions at the place of storage:

■

Storage temperature: -20 ... +70 °C

■

Humidity: < 90 % rel., non-condensing

WARNING!

Before storing the digital pressure gauge (following operation), remove any residual media.

This is of particular importance if the medium is hazardous to health, e.g. caustic, toxic,

carcinogenic, radioactive, etc..

6. Commissioning, operation

CAUTION!

Prior to commissioning, the digital pressure gauge must be subjected to a visual inspection.

Only use the digital pressure gauge if it is in perfect condition with respect to safety.

Required tool: Open-ended spanner (spanner width 27)

6.1 Mechanical mounting

■

The sealing faces at the instrument have to be

undamaged and clean.

■

When screwing the instrument in, the force

required to do this must not be applied through

the case, but only through the spanner ats

provided for this purpose and using a suitable

tool.

The correct torque depends on the dimensions

of the process connection and the gasket used

(form/material).

Do not overwind the process connection, do not exceed the permissible torques.

■

When screwing in, do not cross the threads.

■

For information on tapped holes and welding sockets, see Technical information IN 00.14

at www.wika.com.

Sealing of the process connection

For further information on sealings see WIKA data sheet AC 09.08 or under www.wika.com.

Rotatability of the case

The case of the model DG-10-E can be rotated through 300°, thus the

display can be read from almost any position.

Do not turn the case forcibly past the stop point.

Parallel threads Tapered threads

Correct sealing of the process connections with

parallel threads at the sealing face  must be

made using suitable at gaskets, sealing rings or

WIKA prole sealings.

For sealing process connections with tapered

threads, the sealing must be made in the threads

using additional sealing material, e.g. PTFE tape

(EN 837-2).

6.2 Voltage supply

The power supply for the digital pressure gauge is provided via two 1.5 V AA cells.

The operating time is approx. 4,000 hours, when using batteries with a capacity of 2,000 mAh.

Battery status

The battery status is shown by a battery symbol in the display (see

chapter 6.3 "Description of the digital indicator").

Change the batteries as follows, as soon as the battery symbol

shows no bars and is blinking.

6. Commissioning, operation

Backlighting (model DG-10-E)

The model DG-10-E features backlighting so that the display can

be easily read, even under poor lighting conditions.

After pressing any key, the display will light up for 7 seconds.

The backlighting can be switched on and o via the menu item

"LIGH", see chapter 6.4 "Menu navigation in the programming

mode, model DG-10-E".

6.4 Keys and functions

Bargraph display with drag pointer function

The additional integrated bargraph with drag-pointer function within the display indicates the trend of

the current pressure directly, independently from the digital indicator. Using the drag-pointer function,

the max. memory value is also displayed in the bargraph display in the form of a bar segment, as well

as in the digital indicator. On resetting the MIN/MAX value, this bargraph is then updated to the current

measured value.

11250313.03 09/2012 GB/D/F/E

GB

MIN/MAX memory

The MIN/MAX memory is reset to the current measured value with each measuring cycle.

Tare function "TARE" (model DG-10-E)

In this mode, the positive deviation of the measured value from the tared value (max. 20 % of the

measuring range) is shown on the main display. The non-tared value is shown on the bargraph display,

so that you can always read the current utilisation of the digital pressure gauge.

The following possibilities can be activated for the tare function:

■

Select the tare function via the "TARE" menu item. Use the arrow keys to adjust the value to be tared.

The adjusted value to be tared will be stored in the memory as tare.

■

Load the digital pressure gauge to the pressure to be tared. The main display will show the current

measured value. Via the menu, select the tare function, "TARE", and press the two arrow keys

simultaneously. The current measured value will be stored as tare. The main and secondary display

will be set to "0000".

The tare function can be reset in both variants by setting the tare value to "0000".
