3. Installation

3.1 Assembly information

• Keep in mind that this device is an electronic precision measuring device. Handle the de-vice

carefully and properly to avoid any damages!

• Do not throw the device!

• Remove the packaging and, if necessary, the protective cap of the device only shortly before

installation in order to prevent damage to the diaphragm!

• Keep the protective cap!

• After disassembling, reattach this protective cap over the diaphragm.

• Handle an unprotected membrane with extreme care; This can be easily damaged.

• Do not use any force when installing the devices!

• Make sure that no mechanical stresses occur at the pressure port with low pressure ranges

during installation, as this may cause a shifting of the characteristic curve..

• For the connection of the pressure lines, a sealing has to be installed by the operator.

• For the pipe assembly, an installation as zero-potential as possible must be observed.

• Consider for the installation of a DMU 10 D, that the pressure ports must not be turned

against the housing!

3.2 General installation steps

1. Remove the pressure measuring device from the package carefully.

2. Connect the reference pressures according to the following installation steps

and to your mechanical connections. Therefore, you will have to observe that:

- The higher pressure must be connected with the input "+" (DMU 10 D) or

"P1" (DMU 11 D)

- The lower pressure must be connected with the input "-" (DMU 10 D) or

"P2" (DMU 11 D)
