Note:

Approx. 10 minutes after the last pressing of a key, an

automatic reset to measured value indication is triggered. Any

values not conﬁrmed with [OK] will not be saved.

6.2 Setup procedure

Setup encompasses mainly the selection of the application

and the adjustment of the measurement loop. Scaling the

measured value to the requested size and unit (possibly also

applying a linearization curve), as well as the adaptation of the

relay switching points, are additional settings. Further setup

steps might be, if necessary, the modiﬁcation of the current

output characteristics or the setting of an integration time to

smooth the measured value.

For instruments with Ethernet interface, the instrument must be

provided with the host name and IP addr./Subnet mask. If

necessary, the e-mail/web server can also be conﬁgured with

PACTware™.

VEGAMET 625 can process measured values of several

connected HART sensors. All measured values are trans-

mitted as digital HART signals on the same cable (bus).

Therefore an own, unique address (address range 1-15) must

be assigned ﬁrst of all to each connected sensor. This mode is

also called HART Multidrop mode. Addressing can be done

directly on each HART sensor via the respective adjustment

unit or an appropriate adjustment software. As an alternative,

the setting of the sensor address can be also carried out via

the VEGAMET menu under "Service – Sensor address".

Note:

When addresses are being assigned, only one sensor with a

particular address must be connected on the bus. If this is not

the case, the sensor cannot be accessed and it is not possible

to assign an address.

After being switched on, VEGAMET 625 ﬁrst of all carries out a

short self-check. The following steps are carried out:

Set HART address
