What to do if Rosemount 8800D have communication problems with HART-based Communicator?
- N
  Nicholas BowersJul 27, 2025
  If you are experiencing communication problems, you can take the following steps: * Ensure a minimum of 10.8 Vdc at the transmitter terminals. * Check the communications loop with a HART-based communicator. * Verify the presence of a loop resistor (250 to 1000 ohms). * Measure the loop resistor value (R) and source power loop supply voltage (V). Confirm that [V - (R x 0.024)] > 10.8 Vdc. * Check if the transmitter is in multidrop or burst mode. * Remove the pulse connection if you have a three-wire pulse installation. * If the issue persists, consider replacing the electronics.

What to do if Rosemount Measuring Instruments have incorrect 4–20 mA output?
- N
  nina05Aug 3, 2025
  If the 4–20 mA output is incorrect, you can take the following steps: * Check for a minimum of 10.8 Vdc at the transmitter terminals. * Verify URV, LRV, Density, Special Units, and LFC, comparing these inputs with the sizing program results. Correct the configuration if needed. * Perform a 4–20 mA loop test. * Inspect the terminal block for corrosion. * If necessary, replace the electronics.

What to do if Rosemount 8800D Measuring Instruments have flow in pipe but no transmitter output?
- D
  Dr. Paul GrantAug 11, 2025
  If there is flow in the pipe but no transmitter output, consider the following: * Check the torque on the sensor nut (32 ft-lb). For 1-8 inch meter body with ANSI 1500 flanges, the torque should be 50 ft-lbs. * Inspect the coaxial sensor cable for cracks and replace it if necessary. * Verify that the sensor impedance at process temperature is > 1 Mega-Ohm (it will function down to 0.5 Mega-Ohms). Replace the sensor if needed. * Measure the sensor capacitance at the SMA connector (115-700pF).

What to do if Rosemount 8800D Measuring Instruments have incorrect pulse output?
- E
  Erica BrewerAug 19, 2025
  If the pulse output is incorrect, consider the following: * Check that the 4–20 mA output is correct. * Check the pulse counter specifications. * Check the pulse mode and scaling factor, ensuring the scaling factor is not inverted. * Perform a pulse test. * Select pulse scaling so that pulse output is less than 10,000Hz at URV.
