You adjust the sensor via the four keys of the display and adjustment
module. The individual menu items are shown on the LC display. You
can find the functions of the individual keys in the previous illustration.
By pushing the [+] and [->] keys once, the edited value or the cursor
changes by one position. By pushing the keys longer than 1 s the
change will be continuously.
By pushing the [OK] and [ESC] keys simultaneously for more than
5 s, a return to the basic menu is caused. The menu language is then
switched over to "English".
Approx. 60 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.
After switching on, the SITRANS LG250 carries out a short self-test
where the device software is checked.
The output signal transmits a fault signal during the switch-on phase.
The following information is displayed on the display and adjustment
module during the startup procedure:
•
Instrument type
•
Device name
•
Software version (SW-Ver)
•
Hardware version (HW-Ver)
With the [->] key you can move between three different indication
modes.
In the first view, the selected measured value is displayed in large
digits.
In the second view, the selected measured value and a correspond-
ing bar graph presentation are displayed.
In the third view, the selected measured value as well as a second
selectable value, e.g. the temperature, are displayed.
