13. Inspection before Power-On
1. Check whether the flow meter is damaged during transportation and installation.
2. Check whether the voltage of the power supply is consistent with that specified on
the nameplate.
3. Check whether the fuse used is of the correct current value.
4. Check whether the flow meter is grounded correctly.
5. Open the pipe valve to fill the pipeline system with liquid. One should pay attention
to removing the leaked gas and residuals in the system.
6. Power on the flow meter to warm up for 10 minutes. Then it can work normally.
