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
Through parameter adjustment, the instrument is adapted to the
individual application conditions. Calibration of the measuring point is
the most important step and should always be carried out. A scaling of
the measured value to the desired physical variable and unit, possibly
including a linearization curve, is often useful. The adaptation of the
relay switching points or the setting of an integration time to smooth the
measured value are further standard adjustment options.
For instruments with Ethernet interface, the instrument must be
provided with an IP address and subnet mask suitable for the
instrument. As an alternative, addressing via DHCP and a host name
is also possible. If necessary, the e -mail/webserver can be also
configured with PACTware.
A setup assistant is available for easy, convenient setup. It guides the
user through the standard applications and settings step by step.
Information:
When using PA CTware and the respective DTM, additional settings
can be carried out which are not possible or only partly possible with
the integrated indicating and adjustment unit. Communication is
carried out via the integrated USB interface or one of the optional
interfaces (RS232/Ethernet).
Further instructions for setting up the web server and e-mail functions
are stated in the online help of PACTware or the VEGAMET 391 DTMs
as well as the supplementary instructions manual "RS232/Ethernet
connection".
After being switched on, VEGAMET 391 first of all carries out a short
self-check. The following steps are carried out:
l Internal check of the electronics
l indication of the instrument type, firmware version as well as the
instrument TAG (instrument name)
l The output signals jump briefly to the set fault value
