    In determining the reduced errors normalizing value leveled the upper limit of the measuring range. Limit of permissible variations readings E4202 becomes no more than polutorakratnogo value of the maximum permissible basic error.

    Changes display ammeters, voltmeters E4202 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).
