2.1 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.
2.2 Scope of delivery
Cross-check scope of delivery with delivery note.

5.1 Mechanical mounting
■
The sealing faces at the instrument and at the
measuring location have to be undamaged and
clean.
■
When screwing in the instrument, the force
required to do this must not be applied through
the case, but only through the spanner flats
provided for this purpose and using a suitable
tool.
The correct torque depends on the dimensions of the process connection and the sealing used
(form/material).
Do not overwind the process connection, do not exceed the permissible torques.
■
When screwing in, do not cross the threads.
■

For sealing the process connections with parallel
threads, use flat gaskets, lens-type sealing rings
or WIKA profile sealings at the sealing face .
For sealing process connections with tapered
threads, the sealing is made in the threads
using additional sealing material, e.g. PTFE tape
(EN 837-2).

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 off via the menu item “LIGH”, see

Bar graph display with drag pointer function
The additional integrated bar graph display 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 bar graph display in the form of a bar segment,
as well as in the digital indicator. On resetting the MIN/MAX value, this bar graph is then updated to the
current measured value.

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 bar graph 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”.
