Technical data
Installation for testing voltmeters V1-8 provides AC and DC voltage up to 300V 10mkV. In this setting gives rms, maximum and srednevypryamlennoe AC voltage and DC voltage of either polarity with nominal values ​​corresponding to the number of 0.4, 0.5, 0.6, 0.7, 0.8, 0.9, 1.0 , 1.5, 2.0, 2.5, 3.0, and stresses that differ from the nominal values ​​ranging from minus 5 to plus 5% from minus 10 to plus 10%.
The basic error of nominal output voltage does not exceed t ± (0,15 +0,0003 / U nom)% - DC, ± (0,3 + 0,0003 / U nom)% for AC, where U nom - the nominal output voltage, V output voltage accuracy at a deviation from the nominal value of ± 5% at constant current does not exceed ± (0, 25 + 0,0003 / U nom)% for AC - ± (0,4 + 0,0003 / U nom)%, and with a deviation of ± 10% at constant current does not exceed ± (0,25 + 0 0003 / U nom)%, on an alternating current - ± (0,5 +0,0003 U nom)%.
Installation for testing voltmeters V1-8 produces an alternating voltage frequency of 45, 400 and 1000 Hz. The error fixed frequency does not exceed ± 5%. The variable component of the DC output voltage of either polarity is less than ± 0,01% of the nominal output voltage.
Harmonic Distortion Output voltage alternating current does not exceed 0.2%. Additional error nominal output voltages caused by the deviation of the ambient temperature from normal to any temperature within the operating temperature range does not exceed half of the maximum permissible basic error of the DC and the maximum permissible basic error on alternating current for every 10 ° C change in temperature. Additional error of nominal output voltage values ​​due to changes in humidity and temperature of the environment in the working conditions, does not exceed twice the value, the maximum permissible basic error on direct current. Additional error of the output voltage caused by the deviation of the voltage at 50 Hz from the nominal value by ± 10% and a frequency of 400 Hz ± 5%, no more than half of the maximum permissible basic error.
Installation for testing voltmeters V1-8 enables calibration of voltmeters with an input impedance of at least 100 kW. Additional error of the output voltage setting caused by external load 100 ohms, does not exceed 0.15%.
DC output voltage at the socket for connecting an external device to the impedance at least 1 Mohm is (100 ± 2) mV error index scale mounted on end of the scale.
The time setting of the output voltage does not exceed 10. The unit provides its specifications after samoprogreva time of 30 minutes under normal conditions and 1 h - in the field.
Installation for testing voltmeters V1-8 retains its specifications from eating it from the AC voltage (220-22), frequency (50 ± 0,2) Hz, harmonic content up to 5% and the voltage (220 ± 11) , frequency (400 +28 / -12) Hz and harmonic content to 5%.
