Frequency E372 (E-372, E 372)
Frequency E372 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).
Dimensions - 120h120h89mm.
Accuracy class - 2.5.
Tryaskoprochny, vibration.
Technical characteristics of the instrument E372 frequency counters:
Devices 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 E372 used to work at an ambient temperature of -40 º C to +50 º C and relative humidity up to 95% (at 30 º C).
Power consumption of devices, connected via voltage measuring transformers is 0.7 ∙ ∙ A-3B, A.
Settling time of mobile devices E372 frequency - less than 4 seconds.
Operating position of instruments - upright.
The scale of the device frequency E372 - beznulevaya, uniform.
The change of reading due to the deviation of the ambient temperature of 20 º C to 50 º C (class H) does not exceed ± 1,2%.
