What to do if Emerson Measuring Instruments have communication problems with HART-based Communicator?
- M
  Maria BaileyAug 4, 2025
  If you're experiencing communication issues, begin by ensuring a minimum of 10.8 Vdc at the transmitter terminals. Verify the communications loop with a HART-based communicator and check for a loop resistor between 250 to 1000 ohms. Measure the loop resistor value (R) and source loop power supply voltage (V). Confirm that [V - (R x 0.024)] > 10.8 Vdc. Also, check if the transmitter is in multidrop or burst mode. If you have a three-wire pulse installation, remove the pulse connection. If problems persist, consider replacing the electronics.

What to do if Emerson Measuring Instruments show incorrect 4–20 mA Output?
- J
  Jean MurilloAug 12, 2025
  If the 4–20 mA output is incorrect, first, ensure a minimum of 10.8 Vdc at the transmitter terminals. Then, check the URV, LRV, Density, Special Units, and LFC, comparing these inputs with the sizing program results to correct the configuration. Perform a 4–20 mA loop test and inspect the terminal block for corrosion. If issues persist, replace the electronics.

What to do if Emerson Measuring Instruments give incorrect Pulse Output?
- A

  If the pulse output is incorrect, start by checking that the 4–20 mA output is correct. Then, check the pulse counter specifications, pulse mode, and scaling factor, ensuring the scaling factor is not inverted. Perform a pulse test and select pulse scaling so that pulse output is less than 10,000Hz at URV.
