The limits of the scale (initial and final values of the measuring range) limits. Allowed values of the basic errors of the device in normal conditions of use (Table 2), the values of current consumption device correspond to the values specified in Table 1;
Table 1: Values of the combined unit of consumed electrical analog device current 43102
Table 2 Limits. Allowed values of the basic errors of the combined unit of electrical analogue instrument 43102 in normal conditions of use
The limits of acceptable basic and additional errors in the combined unit of electrical analogue instrument 43102 expressed in the form of error given by the formula:
γ = ± ((100 ∙ Δ) / X)
where Δ - the absolute error, X - normalizing value.
Normalizing values are given in determining the errors are:
- When measuring DC and AC current, frequency, engine speed and the angle of the closed state of the breaker contacts - a finite value of the measurement range;
- When measuring the DC resistance - the entire length of the scale, with a minimum of:
- 46mm - for measuring range 0 k, 100 k;
- 54mm - for measuring range 0 MW-100 MW;
The limits of permissible values of the combined instrument additional errors electrical analogue instrument 43102 due to the slope of the device by 10 ° in any direction from the changes of ambient temperature for each 10 ° C does not exceed the limit of acceptable basic error;
The limit of permissible values of additional errors from the influence of external DC and AC sinusoidal magnetic field with induction 0.5 mT do not exceed ± 1,5%;
The limits of permissible values of the combined instrument additional errors electrical analog device is less than half the 43102 limit of acceptable basic error when installing the device on the basis of ferromagnetic thickness of 2 mm ± 0,5 mm and placed under the influence right up to him a similar device to this is at a distance of at least one m;
Limit of acceptable additional error of the instrument caused by the deviation of the voltage curve of the normal value under the influence of the 2nd, 3rd or 5th harmonic component is equal to 5% of the rms value of the measured voltage does not exceed ± 5%; '
