Technical data
In terms of resistance to mechanical stress during use Voltmeters Э531 belong to group 2 according to GOST 22261-76.
Settling time the movable part of the instrument Voltmeter Э531 not more than 4 when
temperature of 15 to 20 °C. the Limit of additional
error of the instrument Voltmeter Э531 equal to the maximum permissible
error: frequency deviation of ± 10% from the end of normal
range of frequencies, the frequency deviation from the limits of the normal range of frequencies
to any frequency in the working frequency range.
Limit of permissible additional error of the instrument Voltmeter Э531,
caused by the change of ambient temperature from normal
(normal conditions in accordance with GOST 8711-78) to any temperature within
the operating temperature for every 10 °C change in temperature, is ±0,5% of
the final value of the measuring range.
