MENU FUNCTIONS
Step 2: Press the
(up arrow key) or
key) until the word UPDATE appears.
Step 3: Press Enter.
Step 4: Press the
(up arrow key) or
key) to select an update rate.
Step 5: Press ENTER to finalize the selection.
DAMP or dampening: with five different options, this mode
allows for taking process pressure readings and averaging
them. This option is particularly useful to stabilize minor
process fluctuations. The options are NONE*, AVG 8, AVG
6, AVG 4, AVG 2.
Step 1: Press the MENU key until the word dAMP appears.
Step 2: Press Enter
Step 3: Press the
(up arrow key) or
key) to select a dampening option.
Step 4: Press the ENTER key to finalize your Damp option.
(This Menu item is only seen on units with the switch option)
SWSET: Allows for setting switch setpoints. The gauge is
offered with one or two SPDT switches. If (one) SPDT
switch is ordered the menu option is SW1. If (two) SPDT
switches are ordered, the MENU options are SW1 and SW2.
Step 1: Press the MENU key.
Step 2: Press the
(up arrow key) or
key) on the keypad to select the switch to be set. (If two
switches are present.)
Step 3: Press ENTER. The top line of the gauge display will
indicate pressure at 60% of the fullscale gauge range* or
the most recent switch setpoint. The middle line of the dis-
play will indicate a bar graph that displays the pressure
position within the pressure range. The bottom line will
display SETPT (blinking).
*Indicates default.

MENU FUNCTIONS
Note: Setpoints are limited to the full-scale pressure range
of the gauge.
Step 4: Press the
(up arrow key) or
on the keypad to increase or decrease switch set-point
Step 5: Press the ENTER key to finalize switch setpoint. The
gauge will display SET. After two seconds, the top line will
indicate RETRP pressure. The bottom line will read SET.
Step 6: Repeat above to set RETRP (retrip value) If the
gauge is supplied with (one) setpoint, the screen will
advance to the measurement mode. If (two) switches are
supplied the display will advance to SW2.
Repeat the aforementioned if the gauge is supplied with
two switches.
Notes: The bar graph will increase or decrease as any
setpoint pressure is adjusted. The bar graph indicates
switch setpoint position within the full-scale pressure
range of the gauge.
The switch setpoint unit of pressure measurement corre-
sponds with the current set unit of measure of the gauge.
If gauge unit of measurement is changed after switch(es)
is set, switch setpoint(s) will automatically be updated to
correspond with revised unit of measurement. Switch
deadband is the difference between the SETPT (setpoint)
and the RETRP (retrip) pressure.
