E4205 ammeter, voltmeter E4205
Also, this device can be called: E-4205, E 4205, Є4205, Є-4205, Є 4205, e 4205, e-4205, e 4205.
Ammeter, voltmeter E4205 - the device of an electromagnetic system to measure current and voltage in AC circuits.
The device has a dial type of display measurement information. FFL is placed on the edge of the measuring range. E4205 works by interaction of the magnetic field of the measured current flowing through the coil and the core, which, depending on the magnitude of the current, is drawn into the coil window.
Technical characteristics of the devices ammeters, voltmeters E4205
Dimensions 60x60x50 mm.
Scale length - 65 mm.
Accuracy class 1.5, 2.5.
Ranges devices and related methods include in the table.
Normal rate instruments - 50, 60,200,400, 500, 800, 1000 Hz.
In determining the reduced errors normalizing value leveled the upper limit of the measuring range. Limit of permissible variations readings E4205 becomes no more than polutorakratnogo value of the maximum permissible basic error.
Changes display ammeters, voltmeters E4205 can be caused by:
- Changing the position of the device from its normal position in any direction by 5 ° (the value of reading changes - less than half the limit of acceptable basic error);
- Frequency deviation of ± 10% of the normal rate (change of testimony - no more than the limit of acceptable basic error);
- The influence of external homogeneous magnetic field of 0.4 kA / m (changing testimony - ± 6%);
- Deviation of the ambient temperature from normal to 50 ° C or minus 40 ° C (the amount of change of indications - no more than ± 1,2);
- Deviation from the normal relative humidity up to 95% at a temperature of 35 ° C (change of testimony - no more than the limit of acceptable basic error).
