Setting Example 1: Pressure Display Mode
Using a standard pressure range of 0 to 100 psi, the steps to
change the display and analog output zero and span points to 10
and 90 psi respectively are as follows: First, set the Filter. In this
case set at 8 times (where the output is based upon the moving av-
erage equivalent to the pressure data per 30ms for 8 “periods”
(240ms).
After Power On, hold “M” button >3 seconds to enter Setting Mode.
Display will show “U xxx” (version control), press “M” to enter Filter
selection option, display will show “F” and the setting, use Up and
Down arrow keys for desired setting. To move from Setting item 1 to
2 (etc.) press M, when desired Setting function has been com-
pleted hold the “M” button for greater than 3 seconds to return to
Measurement Mode.
Note: see page 24 for full menu.

While in Setting Mode press “M” button until display shows “A
000.0”, using Up and Down arrow keys adjust to desired setting
which is set as a % of FS, thus to display and output 10psi adjust
using Up Key until “10.0” is showing, then press “M,” display will
show “A 100.0” which is for Span adjustment as a %FS, thus using
Down key adjust value to “90.0” which will correspond to 90psi
(20mA) as the new Full Scale value.
