This chronometer has been designed as an accessory to our injection instruments to test protective relays. Its function is to determine one of the most important parameters, the reaction of the delay time of a protection relay in relation to a trip condition. The time between activation / deactivation of any electrical contact can be measured.

APPLICATIONS

- Measures the trip time in protective relays.
- Measures the time of contact operation.
- Measures the duration of a signal pulse.

CHARACTERISTICS

- Accuracy: ± 0.01%.
- 3 selectable display modes: s, cycles, Hz.
- Resolution: 1 ms.
