Milliampermetr D5098 (D 5098, D-5098)
Ammeters D5098, D5098 milliammeters designed for accurate measurement of current in AC and DC, as well as less accurate calibration devices.
Milliammeter D5098 is designed for use in moderate climate in enclosed dry heated rooms at the ambient temperature of 10 to 35 ° C and a relative humidity of 80% at a temperature of 25 ° C.
Milliammeter -04.1 D5098 is designed for use in both dry and humid tropical climate indoors 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.
Milliammeters D5098 accuracy class 0.1 in accordance with GOST 8711-78. Major instrumental parameters are listed in the table.

Ambient temperature 20 ° C (when the front part of the device is not explicitly stated otherwise.) permissible deviation of ± 2 ° C;
ambient relative humidity of 30-80% atmospheric pressure 84-106 kPa (630-795 mm Hg);
the orientation of the device relative to the magnetic field of the earth - any;
external magnetic field (besides the earth's field) is almost absent;
ferromagnetic base is absent;
waveform distortion factor of voltage and current is not more than 5%:
Frequency - within the normal region;
voltage for the power meter - rated with a tolerance of ± 2%;
power factor - nominal;
the potential difference between parallel and serial connections wattmeter virtually absent;
position of the device - the horizontal;
measurements are carried out after the establishment of the operating mode.
Maximum permissible error of the instrument Milliammeter D5098 in the normal range of frequencies and direct current is ± 0,1% of the final value of the measuring range. The limit of additional instrument error caused by the frequency deviation from the upper limit of normal values to any frequency in the working frequency range is ± 0,1% of the final value of the measuring range.
Response time unit Milliammeter D5098 does not exceed 3 seconds. The limit of additional instrument error caused by changes in ambient-temperature from normal to any temperature within the operating range is ± 0,1% of the final value of the measuring range for each 10 ° C change in temperature.
The limit of additional error device Milliammeter D5098 caused by the influence of external homogeneous constant or variable (frequency within the normal range of frequencies) of the magnetic field with an induction of 0.1 mT, is equal to ± 0,1% of the final value of the measuring range.
Dining lighting circuit unit Milliammeter D5098 is powered by the AC voltage (220 ± 22) V, 50-60 Hz through a step-down transformer, can be combined with the unit, or from a DC or AC voltage (4 ± 0,4) B.
