Information:
The trend recording is not activated when being shipped. It must be
started by the user via the menu item "Start trend curve".
A comparison of the echo curve and the false echo curve allows a
more detailled evaluation of measurement reliability. The selected
curve is updated continuously. With the [OK] key, a submenu with
zoom functions is opened.
The following functions are available with "Echo and false echo
curve":
•
"X-Zoom": Zoom function for the meas. distance
•
"Y-Zoom": 1, 2, 5 and 10x signal magnification in "dB"
•
"Unzoom": Reset the presentation to the nominal measuring range
with single magnification
In the menu item "Trend curve" the following are available:
•
"X-Zoom": Resolution
– 1 minute
– 1 hour
– 1 day
•
"Stop/Start": Interrupt a recording or start a new recording
•
"Unzoom": Reset the resolution to minutes
As default setting, the recording pattern has 1 minute. With the adjust-
ment software PACTware, this pattern can be also set to 1 hour or 1
day.
Echo curve
In this menu item you simulate a user-defined level or pressure value
via the current output. This allows you to test the signal path, e.g.
through connected indicating instruments or the input card of the
control system.
The following simulation variables are available:
•
Percent
•
Current
•
Pressure (with pressure transmitters)
•
Distance (with radar and guided microwave)
With Profibus PA sensors, the selection of the simulated value is
made via the "Channel" in the menu "Basic adjustments".
How to start the simulation:
1. Push
[OK]
2. Select the requested simulation variable with [->] and confirm
with [OK].
3. Set the requested numerical value with [+] and [->].
4. Push
[OK]
