PRESSURE Setup Checklist
1. Make sure PRESSURE sensor type is selected
(see System Setup Menu, page 25).
2. If LOOP is used, set the minimum and maximum 4 to 20 mA setpoints.
3. Set Units of Measurement (PSI, BAR, KPa).
4. Set Last Cal Date and initials.
5. If desired, set up relay functions for your own application.
This is the normal display
and does not time out.
CAL Menu
ON prevents relays from activating while making adjustments, and relays in PULSE mode will suspend
pulsing. Output is held until the user exits the CAL menu. Select OFF/ON.
Default = OFF.
With process pressure at zero, set zero point for measurement.
Calibrate pressure reading to external reference. Provides a maximum 5 psi offset.
Resets calibration to factory default. After pressing
►
, select YES/NO.
Enter date of calibration (mm-dd-yyyy) and initials of calibrator (II)
INPUT Menu
Enter string up to 13 characters (optional).
Default = PRESSURE.
Enter units of pressure measurement. Select PSI, BAR, or KPa.
Default = PSI.
Dampens display, output and relay response rates.
Select: Low, Med, High, OFF (see discussion in Appendix.)
Default = OFF. Signet strongly recommends leaving averaging OFF for pH and pressure measurements
(see discussion in Appendix).
VIEW Mode Menu
Displays the 4 to 20 mA LOOP output
Bottom line shows one of three states (OFF, ON, PLS) for each of the three relays. Displays remaining
time for CYC LOW or CYC HIGH mode. The relay(s) will remain ON while counting down.
NOTE:
(Reset the Timer) In the RELAY menu, select TEST RELAY function. The timer will reset to 0 if
the condition no longer exists when the TEST is performed.
The timer will restart if the condition still exists.
