Voltmeter D5081 (D 5081, D-5081)
Designed to measure the voltage in the DC and AC, and also for testing less precise instruments.
Size not more 65h85h45mm.
Accuracy class 0.2.

Voltmeters D5081 are designed to measure the voltage in the DC and AC, and also for testing less precise instruments.
Voltmeters D5081 are designed for use in moderate climate in enclosed dry heated rooms, at an ambient temperature of 10 ° to 35 ° C and a relative humidity of 80% (at 25 ° C).
Voltmeters D5081-04.1 (tropical version) 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 25 ° C (GOST 15150-69).

Technical data

Voltmeter D5081 corresponds to the accuracy class 0.2 in accordance with GOST 8711-78.
Basic unit voltmeter D5081 shown in Tables 1-3. The limit of additional error D5081 instrument voltmeter, frequency deviation caused by the upper limit of the normal region to any value in the working frequency range does not exceed ± 0,2% of the final value of the measuring range.
The limit of additional error D5081 instrument voltmeter, caused by changes in ambient temperature from normal to any temperature within the operating temperature for every 10 ° C change in temperature is ± 0,2% of the final value of the measuring range. Normal temperature of - 20 ± 2 ° C, if the front of the device otherwise stated meaning.
Change D5081 voltmeter readings caused by the influence of external homogeneous constant magnetic field, and the field varying sinusoidally in time with frequency (within the normal region), equal to the frequency of the current flowing through the measuring circuits of the device is equal to ± 0,2% of final the value of the measuring range at a value of the magnetic field, not exceeding 0.2 mT at a frequency of 1 kHz and 0.13 mT - at a frequency of 1,5 kHz.
Response time less than 3s. Dining lighting circuit unit voltmeter D5081 is made from the AC voltage (220 ± 22) at 50 - 60 Hz via a step-down transformer (supplied with the devices), or directly from an AC or DC voltage (4 ± 0,4) B.
Overall dimensions not more than (205 ± 1,45) x (290 ± 1,6) x (135 ± 2,0) mm, weight of the unit is not more than 4.3 kg. Overall dimensions of the transformer housing no more than 65h85h45 mm, weight of the transformer is not more than 0.5 kg.
