D5065 portable watt meters, ferrodinamicheskoy system with a moving part on extensions are designed to measure active power in single-phase electrical circuits, AC and DC.
Wattmeter D5065 is designed for use in moderate climate in enclosed dry heated rooms at the ambient temperature of 5 to 40 ° C and a relative humidity of 90% at 25 ° C;
Wattmeter D5065 -04.1 designed for use in both dry and humid tropical climate in closed rooms with air conditioned or partially air-conditioned at the ambient temperature from 1 to 45 ° C and a relative humidity of 80% at a temperature of 25 ° C.
Power meter accuracy class 0.5 in accordance with GOST 8476-78. The main parameters are specified in the power meter D5065. Table 1. Rated power factor wattmeter 1. Current branch circuit power meter (3 ± 0,06) mA. The normal frequency range power meter from 45 to 65 Hz, the operating frequency range - more than 65 to 500 Hz.
Maximum permissible error D5065 watt meter in the normal range of frequencies and direct current is ± 0,5% of the final value of the measuring range. The limit of additional error D5065-watt meter, caused by a deflection voltage of ± 20% of nominal value at a constant value of the measured power is equal to ± 0,5% of the final value of the measuring range.
The limit of additional error D5065 power meter, frequency deviation caused by the upper limit of the normal range of frequencies to any frequency value in the working frequency range is ± 0,5% of the final value of the measuring range. The limit of additional error-watt meter D5065 caused by changes in ambient temperature from normal (20 ± 2) ° C to any temperature within the operating range is ± 0,5% of the final value of the measuring range for each 10 ° C change in temperature.
