The measurement unit can be switched between milliseconds and cycles at any time. A special measurement mode can display the frequency of a voltage signal up to 4 kHz. When used in combination with PTE relay test sets, the PTE-30-CH can also be controlled remotely over the built-in PTE BUS interface.
Accuracy: ? 0.01%.
3 selectable display modes: s, cycles, Hz.
Resolution: 1 ms.
Measures the trip time in protective relays.
Measures the time of contact operation.
