• Segment Test:
All pixels on the display are driven; those that are intact will flash! When the segment
test is switched off the last text to be displayed will reappear. System messages dis-
played previously will not reappear!
Please note: To maintain equal brightness on all display segments, we recom-
mend that you run the segment test every week for approximately 3 hours.
• Output Version Number:
The version number will be displayed in the following format: "PX 30, Version x.xx" or
"PX 120, Version x.xx". This is the default message on power-up.
• Auto display of text memory contents:
When this is switched on, all records from 1 ... 9999 are automatically displayed one
after the other. Available records are displayed with their text; for records that are not
available, the text number will appear in the format: "xxxx" (xxxx ... corresponding text
number). The unit will automatically switch off after record number 9 999 is displayed.
• Clear display:
The display and all variable positions are cleared.
• Status display:
The current status of data inputs (PX 30: E7 ... E0; PX 120: E15 ... E0) are shown on
the display as "0" and "1". The lowest value input is shown on the right hand side. The
status display can be switched off at control inputs E23 ... E16, using the code 5C
H
(0101 1100 binary).
The function and layout of inputs in special mode is the same for binary as for BCD-mode.
