Technical characteristics of the devices phasemeter D39:
 
In tropical execution unit is designed for use in rooms with air-conditioned or partially air-conditioned.
Class of accuracy of the instrument phase meter D39 - 2.5.
Acceptable basic error phase meter does not exceed ± 2,5% of measuring range.
Variation of phase meter readings D39 - does not exceed 3.75% of range.
Measuring range sosφ - 0,5-0-0,5.
D39 phase meter is designed to enable a current transformer with a secondary winding on the 5A and the inclusion of a measuring voltage transformer with a secondary winding on 100V.
The change of reading due to ambient temperature deviation from the normal for every 10 K does not exceed ± 2,0%;
- Under the influence of a magnetic field of 400 A / m - for 50Hz, 500Hz, 1000Hz, 160 A / m for frequencies 2400Gts, 100A / m - for the frequency of 4000Hz, 50 A / m - for the frequency of 8000Hz and 40A / m for frequencies 10000Gts - not than ± 5,0%.
Instrument D39 phase meter is designed to work in an upright position.
