7: Identify the true statement.
Online monitoring equipment does not check if a parameter has changed or exceeded a preset limit.
You can find the answer here >
7: Identify the true statement.
If all the parameters are recorded immediately after the pump has been installed, you can use them as benchmark against future data.
