6. Commissioning, operation
6. Top up reservoir if necessary.
Wear safety goggles!

6.4.3 Post assembly test
1. Carry out a test calibration of a known instrument (see chapter 6.6 "Procedure") to
ensure that the unit is working correctly.
2. Release the pressure and remove the test instrument.
To remove the instrument from the system, use the appropriate size
of spanners on the top section of the pressure connection and on the
body of the instrument only. Ensure that the lower part of the pressure
connection is not rotated as this may release it from the base.
3. The system is now ready for use.
When testing equipment with a large volume, the capacity of the spindle
pump (65 cm³) may be insufficient to reach the pressure required. In this
case, the equipment should be filled as far as possible with the liquid
before connecting it to the system, so that the displacement needed is
reduced.
Dirty or chemically contaminated test items should not be fitted as they
contaminate the system unless they are first cleaned.
Wear safety goggles!
Protect eyes from flying particles and liquid splashes.
6.5 Procedure
1. Fit instrument to be tested to a test connection.
2. Connect the reference measuring instrument to the other test connection.
