Multimeter DMM-4T

DMM-4T

Digital. Three phases indicator.
DMM-4T multimeter is used for monitoring parameters of three-phase electrical network.

Functioning
* independent current measurement for each phase
* direct measurement 0├Ě5A
* indirect measurement using current transformers in standard current work with 1├Ě9000/5A range
* setting indicator to proper current transformer values using three buttons on the indicator's front
* phase voltage and phase to phase voltage measurement
* phase frequency measurement
* selection of indicated voltage and frequency values for a single phase using button on indicator's front

The indicator shows the current load of all three phase, selected by the user or between voltage phases and frequency. The choice we make with the tension points located on the right side of a voltage indicator. Horizontal line - to the left of the index determines the phase voltages, for which the reading voltage phase. The two horizontal lines = pointer to the left of the phase voltages determine for whom the reading voltage between phases.
