6.3. Display/keypad commands
6.3.1. Display mode
In the display mode the transmitters output measurements on the display; dif-
ferent quantities can be scrolled with the arrow keys according to the variables
selected when ordering the transmitter. The first line is scrolled with button
σ
and the second line with button
τ
. All selections are stored with ENTER. The
selected quantities appear on the display also after power failure. After reset
the transmitters are always in the display mode.
The display also shows error messages and alarms if they occur.
6.3.2. Command mode
Press the CL key to enter the command mode. The first display is the main
menu:
The commands can be scrolled with arrow keys. The currently active
command flashes; a command is selected with the ENT key. When a menu is
displayed, either the first command or the currently valid setting flashes. The
CL key takes the transmitter back to the display mode.
6.3.3. Entering numbers
When the transmitter needs numbers to be entered into the program (e.g. when
scaling or setting the analogue outputs, in calibration or when giving the
transmitter an address), the field is either empty or the currently valid figure is
displayed. Any previously given value is deleted with the CL key.
When the field is empty, a cursor blinks at the right side of the display.
Pressing the arrow keys brings either a blank ( ), a comma (,), a dash (-), a full
stop (.) or a number from 0 to 9 on the display. The right character is selected
with ENT; after that the number or numbers move left one step. Entering
numbers is ended with selecting a blank ( ) and pressing ENT. The last charac-
ter entered can be deleted with CL. If CL or ENT key is pressed when the field
is empty, the program returns to the previous display.
With some commands (e.g. calibration) the figures are changed using the ar-
row keys. When an arrow key is pressed continuously for a while, the numbers
start changing at an increasing rate.
