Digital chronometer PTE-30-CH

This chronometer detects state changes in normally open or normally closed contacts, as well as positive or negative changes in voltage up to 250 V (AC or DC). 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. CHARACTERISTICS Accuracy: ± 0.01%. 3 selectable display modes: s, cycles, Hz. Resolution: 1 ms. APPLICATIONS Measures the trip time in protective relays. Measures the time of contact operation. Measures the duration of a signal pulse.
