Basic key operation
The setting item is changed by
k

Notes: 1.Values shown are from example in I&M Manual.
2. Changes made within the Setting Mode are saved
by returning to Measurement Mode before powering
the unit “off.”
Note: Values shown are from example in I&M manual.

Loop Check: Use to send a 4-20mA signal meant to sim-
ulate applied pressure, can be accessed either through
Pressure Display Mode or Linear Display Mode. See
“Complete Setting Mode Menu”; Loop Check is noted on
the screen with a prefix “
(
”. The display is indicating in
actual units and starts at the zero (4mA) point.
If $ button is pressed, the linear display will auto incre-
ment by linkage between the linear display and the analog
output. By continuing to press # button, auto decrement
will occur. Release the button at the desired indication.
