LGMI-16 intrinsically safe teletechnical meter - a universal measuring device used to test the parameters of underground telecommunication networks and other electrical parameters.

DESCRIPTION

The LGMI-16 intrinsically safe teletechnical meter is a universal measuring device used to test underground parameters of telecommunication networks and other electrical parameters. It enables, among others, assessment of the efficiency of telecommunication networks and the size of interference occurring in the tracks. The device allows for measurements of such parameters as: Alternating and direct voltage Alternating and direct current Resistance Signal attenuation The meter also allows for generation of a sinusoidal signal with a given amplitude and frequency. Measurements are made using the "True RMS" method
