Measurements
  1. in case of few chilled water circulation pumps working in the same time during the test, please indicate the current (A) and the flow measured with flow meter of all circulation pumps working together.
  2. the load on the chiller during the test should be at least 70%
  3. measurements of all measured parameters should be at the same time (within 5 minutes)
