Meter of transformation parameters "Coefficient 1.1"

The device "COEFFICIENT-1.1" allows to measure on one phase for transformers of all schemes and connection groups according to GOST 30830:
- transformation coefficient;
- effective (RMS) voltage value.
It is produced in two versions:
- standard (operating temperature range from 5?C to 40?C);
- Northern (operating temperature range from minus 20?C to 45?C), has improved construction and moisture protection.
It has:
- manual or automatic measurement limit selection;
- non-volatile memory for 700 measurement results;
- galvanically isolated RS232 interface for connection to a computer;
- programmable number of measurements with indication of the average value.
