6.1.2 Numeric Display
The 5-digit numeric display can be configured to show one of the following.
•
Transmitter current output (4-20 mA or %, selection shown in the unit/bargraph display)
•
Pressure value, in percent, relative to the set range
•
Measured value in a selectable engineering unit (shown on the unit/bargraph display)
Sign for the Measured Value
When the measured value is a negative number, the minus sign is lighted.
Status Arrows
Table 6-1 shows the modes in which the status arrows are active, as well as the meaning of each arrow for
each mode.

switch point
Magnetic Pushbutton Operation
(Mode 2, 3, 5, or 6) Span to be set exceeds the maximum
span Span to be set is less than the
minimum span
Normal Operation Output current exceeds the upper
saturation limit or
Input pressure exceeds the upper
sensor limit Output current is below the lower
saturation limit or
Input pressure is below the lower
sensor limit
