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.
