3 OPERATING MODE

When power is supplied to the CVM-MINI, the equipment will start its software interface
on the screen showing the version of the firmware and its setting. After a few seconds
the equipment is ready to operate and shows all available screens.
Once started the power analyzer will display the programmable electrical parameters
via the measurement Set-up. If there is no previous setting, the analyzer will display the
voltage between phase and neutral for L1, L12 and L1
