Stopwatch electric PV 53L.

 

Designed to measure the response time of relays or contactors.

Rated voltages 110 and 220 V.

Permissible fluctuations + 20%.

Rated frequency 50 Hz.

The measurement limit of the small scale is 10 s.

Division value 1 s.

Limit: large scale measurements 1 s.

The division value is 0.01 s.

The error at the rated frequency of the supply current does not exceed + 0.03 s when measuring the time interval from 1 to 3 s. and + 0.05 s. when measuring a time interval from 3 to 10 s.

When measuring the total time of several time intervals, the errors are summed up.

The strength of the insulation is tested with a voltage of 2000 V.

Power consumption:

at a voltage of 110 V - 5 VA.

at a voltage of 220 V - 10 VA.

The device is new warehouse storage.
