Troubleshooting
High, Low, or Erratic Output, or No Output at All
Check the Interconnecting Piping

Be sure there are no leaks or blockage in the interconnecting piping

Look for sediment in the sensor process connection(s)
Remove the sediment by purging the connection(s) with a solvent appropriate for your
process.
Caution
Damage may occur to the sensor if the sediment is removed with a
harsh solvent, or by scraping. Therefore:

Do not scrape the inside of the process connection(s).

Only clean the process connection(s) with solvent appropriate
for your process .
Check the Wiring

Ensure the voltage to the transducer is ±15 VDC (±5%) @ 1.0 Amps

Verify that the total current being drawn by the manometer is within the specifications of
the power supply

Check the signal terminals for the correct polarity

Measure the loop impedance

Look for shorts, multiple grounds, and defective wire insulation
If the solutions presented in this chapter fail to resolve the problem, return the transducer to MKS
for servicing. When returning the instrument to MKS, please obtain an RMA Number (Return
Material Authorization Number) from the MKS Calibration and Service Center before shipping.
The RMA Number expedites handling and ensures proper servicing of your instrument.
Refer to the inside of the back cover of this instruction manual for a complete list of MKS
Calibration and Service centers.
Warning
All returns to MKS Instruments must be free of harmful,
corrosive, radioactive, or toxic materials.
