Large Zero Shift when Screwing In
1) Check Hole with Gage Plug and Rework Hole as Required
2) Check Mounting Torque
Primary Milliamp Reading is Low or
High
1) Check Pressure Variable Reading for Saturation
2) Check if Output in Alarm Condition
3) Verify 4 and 20 mA Range Points or Simply Reset
4) Perform 4 - 20 mA Output Trim with HART Communicator
No Response to Changes in Applied
Pressure
1) Check Test Equipment
2) Check Port/Pipe for Blockage or Solidified Plastic
3) Check if Output in Alarm Condition

2) Check Damping
3) Check for EMI
Transmitter Not Communicating with
HART Communicator
1) Check Power Supply Voltage at Transmitter
2) Check Load Resistance (250 Ohm minimum)
3) Check Communicator Connection Across Power Supply
4) Check if Unit is Addressed Properly
5) Confirm HART communicator is connected to primary
(Pressure) output 4-20mA
HART Communicator missing SPX
Features Described in Manual
From the Communicator’s Main Menu, Access the On-Line
Menu. The Name SPX Should be Displayed on the Top Line of
the LCD. If the Name is not Present, Contact Dynisco to
Arrange for DD Upgrade
Primary output =3.6mA or > 21mA
4) Unit is in fail safe, consult fail safe section
