Enk Ihave not received mine yet, but it claims to be able to measure up to 700v RMS. But why would you want to measure mains voltage? Or mains frequency? I would have thought that although the voltage may change bit, the frequency would always be spot on? I think power networks fail quickly if frequencies are off??
