Yokogawa Pressure Transmitter Local Parameter Setting (LPS) Tutorial

We have all run into this scenario one time or another; you're out in the field when you realized you need to make an adjustment to one of your Yokogawa pressure transmitters, but your Hand Held Communicator (HHC) is back at the instrument shop.

If you have a Yokogawa EJA-E or EJX-A series pressure transmitter it is not a problem. Yokogawa's Local Parameter Setting (LPS) gives you easy access to nine (9) basic parameters:
  1. Tag Number
  2. Unit of measure
  3. Set LRV (4 mA)
  4. Set URV (20 mA)
  5. Damping Time
  6. Transfer Function (Linear or Square Root)
  7. Display
  8. Calibrate LRV (Requires applied pressure)
  9. Calibrate URV (Requires applied pressure)
LPS is available on any EJA-E or EJX-A series model with HART (Output Signal code -E or -J) and BRAIN (Output Signal code-D) communication.

LPS requires Integral Indicator with Switch (code E). The LPS utilizes the Range-setting Switch on the indicator and the Zero Adjust Screw to work through the menu and change values.

The video below provides a detailed tutorial on how to use Yokogawa LPS.
