The voltmeter universal & nbsp; DNV & nbsp; - high-voltage divider used to expand the DC voltage measurement limits the input impedance (10 & plusmn; 0,05) Mohm

& nbsp; & nbsp; & nbsp; & nbsp; DNV divider has a range of DC input voltages - 0-40kV. For high voltage products divider DNV voltage dividing ratios of 1: 1000 and 1: 2000, 1: 5000. Thus DNV error is 0.5% or 0,6%

& nbsp;. & Nbsp; & nbsp; & nbsp; Dividers DNV output voltage are input DC resistance & nbsp; (500 & plusmn; 25) ohms and the output impedance of the constant current (0,526 & plusmn; 0,026) Mohm

& nbsp;. & nbsp; & nbsp; & nbsp; Dividers high-voltage DNV & nbsp; made sizes 515 & times; 80 & times; 80 mm and a weight of 1 kg

& nbsp;. & nbsp; & nbsp; & nbsp; specifications DNV

& nbsp; & nbsp; & nbsp; & nbsp; Dividers DNV & nbsp; are supplied with a voltmeter V7-40. They provide a measurement of the DC voltage from 1 kV to 30 kV, and the voltmeter readings correspond to:

& nbsp; & nbsp; & nbsp; & nbsp; - 0,001U (DNV) for measuring DC voltmeter voltage DNV;

& nbsp; & nbsp; & nbsp; & nbsp; - 0,0005U (DNV) for measuring DC voltmeter voltage DNV and shunt K2;

< strong> & nbsp; & nbsp; & nbsp; & nbsp; - 0,0002U (DNV) for measuring DC voltmeter voltage DNV and shunt R3;

& nbsp; & nbsp; & nbsp; & nbsp; where U (DNV) - the value of the measured voltage at the input of the high-voltage divider DNV voltage

& nbsp; & nbsp; & nbsp; & nbsp; divider DNV & nbsp; has the following limits of allowable values ​​of the basic error in measuring the DC voltage equal to:

& nbsp; & nbsp; & nbsp; & nbsp; - voltmeter DNV + / - (0,4 + 0,04 (Uk / U - 1);

& nbsp; & nbsp; & nbsp; & nbsp; - voltmeter DNV and shunt K2 : +/- (0,4 + 0,04 (Uk / Ush1 & nbsp; - 1);

& nbsp; & nbsp; & nbsp; & nbsp; - voltmeter DNV and shunt K3 : +/- (0,4 + 0,04 (Uk / Ush2 & nbsp; - 1);

& nbsp; & nbsp; & nbsp; & nbsp; where Uk - finite value set limit measuring voltmeter (200mV, 2B; 20B; 200B), U = 0,001 U (DNV) Ush1 = 0,0005 U (DNV) Ush2 = 0,0002 U (DNV), U (DNV) - the value of the measured voltage at the input of the high-voltage divider DNV
