The direct

- Maximum permissible error of the instrument EV1605 is ± 1,5% of full scale range for devices with the zero mark on the left, and for devices with the zero mark within the measuring range - from the sum of absolute values ​​of the end of the measuring range;
- Maximum permissible additional error caused by:
- Change in the ambient temperature from the normal 20 º C ± 5 º C and any temperature ranging from -40 º C and +60 º C to 10 º C every temperature change of 50% of the class designation accuracy;
- The influence of an external DC magnetic field strength of 0.4 kA / m is equal to ± 1%;
- Changing the operating position (inclination) of the normal EV1605 device in either direction by 45 º, is ± 1%;
- The installation of the device on a ferromagnetic shield thickness 2mm ± 0,5 mm or influenced located near the device must be equal to ± 0,5%;
- Basic and additional error EV1605 expressed as a percentage of the final value of the measuring range - for units with the zero mark on the edge of the measuring range and the amount of modules of finite values ​​of the measuring range - for units with a zero mark within the range of measurement;
