6.2 Preparations before Turning on Power
(1) Check piping
Check piping and ensure that there are no loose nuts and bolts, or missing gaskets. Make sure that
the density meter is properly connected in the pipeline.
See the section 3.3, Installation and Piping.
(2) Close the valves
Make sure that the drain valve, sampling valve, and zero water valve, which are installed in the
pipeline, are all closed.
(3) Verifying the cable connection
It is verified that cables are correctly connected to their respective terminal blocks. It is verified
that the ground (grounding resister: less than 100 Ω) is reliably connected to this density meter. In
the event of performing an external synchronized operation, the external contact input signal
connected with ON/OFF of the pump is required; therefore, make sure that the external contact
input signal cable is reliably connected.
6.3 Power on and Preparations for Measuring
6.3.1
