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.

APPLICATIONS

- Measures the trip time in protection relays.
- Measures the duration of a signal pulse.

CHARACTERISTICS

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