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 steps
Through parameter adjustment, the instrument is adapted to the indi-
vidual application conditions. A measurement loop calibration 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.
Instruments with Ethernet interface can be provided with a Host name
suitable for the measurement loop. As an alternative to the addressing
via DHCP, it is also possible to adjust an IP address and subnet mask
suitable for your network. If necessary, the e-mail/Web server 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 PACTware and the respective DTM, additional settings
can be carried out which are not possible or only partly possible with
the integrated display 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:
•
Internal check of the electronics
•
indication of the instrument type, firmware version as well as the
instrument TAG (instrument name)
•
The output signals jump briefly to the set fault value
Then the current measured values will be displayed and outputted.
The measured value indication shows the digitally indicated value, the
measurement loop name (measurement loop TAG) and the unit. An
analogue bar graph can also be displayed. If flow measurement with
totalizer is activated, an additional indication window with totalizer be-
comes available. With activated pump control, an additional window
for indication of the assigned pumps is available. By pushing the [>]
key you can move between the different indication options.
