Frequency E371 (E-371, E 371)
Frequency E371 is designed to measure the frequency of the AC circuit in the range of 45Hz-55Hz, 450Gts-550Gts (in circuits with rated voltage of 127V, 220V and 380V) and 180Hz-220Gts (in circuits with a voltage of 220V).
Class of accuracy of the instrument - 2.5.
Dimensions - 160×160×91mm.
Frequency with a measuring range of 45Hz-55Hz and 450Gts-550Gts can be incorporated into the circuit via measuring transformers with a rated voltage of the transformer secondary winding 100B;
Frequency Devices E371 used to work at an ambient temperature of -40 º C to +50 º C and relative humidity up to 95% (at 35 º C);
In terms of resistance to mechanical impact devices are shaking and vibration;
Power consumption frequency devices E371, connected via voltage measuring transformers is 0.7 ∙ ∙ A-3B, A;
Settling time moving part does not exceed 4c;
Operating position frequency devices E371 - vertical;
The scale of the instrument - beznulevaya, uniform;
Changing the frequency of reading E371, caused by deviation of the ambient temperature from -20 º C to +50 º C (class H) does not exceed ± 1,2%;
Weight - 1.8 kg;
The manufacturer guarantees the quality of the device frequency E371 technical requirements specifications subject to user terms and conditions of storage, transportation, installation, operation, established specifications and operational documentation.
