Also, this device can be called: EA-0670, EA 0670, ЄA0670, ЄA-0670 ЄA 0670, ea0670, ea-0670, ea 0670.
Microammeter EA0670 - device-coil system for measuring electrical current in DC circuits.
The device contains a magnet within the framework, the principle of operation is based on the interaction of the magnetic field of the permanent magnet electric current passing through the coil frame.
The device has a uniform scale with an arrow the presentation of information.
Specifications ammeter and EA0670
Dimensions 48 x 48 x 60 mm.
Scale length of 38 mm.
Accuracy class 1.5.
Response time less than 4 seconds.
Measurement ranges and how to enable devices Microammeter EA0670 given in the table.
Accordingly, the accuracy class of the instrument limits of acceptable basic error devices are becoming ± 1,5%.
If the zero mark being on the edge of the measuring range, the fiducial value equal to the upper limit of the measuring range, if the zero mark to be within the range of measurement, the normalizing value of the sum of the modules of the upper limits of the measuring range.
