< strong> basic specifications

& nbsp;

& nbsp; & nbsp; & nbsp; & nbsp; class precision wattmeters 0.5 according to GOST 8476-78. Basic parameters wattmeter & nbsp; D5067ukazany in. Table 1. Rated power factor wattmeter 1. wattmeter current branch circuit (3 & plusmn; 0,06) mA. Normal frequency region wattmeters 45 to 65 Hz, the operating frequency region - over 65 to 500 Hz

& nbsp;. & Nbsp; & nbsp; & nbsp; Maximum permissible error wattmeter & nbsp; D5067 & nbsp; in the normal range of frequencies and at constant stream is & plusmn; 0,5% of the final value of the measuring range. The limit of tolerable additional error wattmeter & nbsp; D5067 induced voltage deviation of & plusmn; 20% of its nominal value at a constant value of the measured power is equal to & plusmn; 0.5% of the final value of the measuring range

& nbsp;. & Nbsp; & nbsp ; & nbsp; Maximum permissible additional error wattmeter & nbsp; D5067 caused frequency deviation from the upper limit of the normal range of frequencies to any frequency value in the operating frequency range is & plusmn; 0,5% of the final value of the measuring range. The limit of tolerable additional error wattmeter & nbsp; D5067, caused by changes in ambient temperature from normal (20 & plusmn; 2) & nbsp; & deg; C to any temperature within the operating range, is & plusmn; 0.5% of the final value of measuring range per 10 & deg; As the temperature changes

& nbsp;. & nbsp; & nbsp; & nbsp; wattmeter Response time does not exceed 4 sec. at a temperature (20 & plusmn; 2) & deg; C. Dimensions wattmeter (140 & plusmn; 1,25) x (195 & plusmn; 1,45) x (92 & plusmn; 2,7) mm. wattmeters mass does not exceed 1.5 kg.
