Purpose
DMM-1T multimeter is used for monitoring parameters of one-phase electrical network.
Functioning
* independent current measurement for each phase
* direct measurement 0÷5A
* indirect measurement using current transformers in standard current work with 1÷9000/5A 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
