GF211B Multi-function Double Clamp Digital Phase Angle Meter
(Accuracy class 1%)
Application
GF211B multi-function double clamp digital phase angle meter is a multi-functional portable instrument. It is an ideal choice for electric power bureau, factories, mine, petroleum-chemistry enterprises, metallurgy factories and so on.
Features
Measure phase angle between two voltages, between two current or between voltage and current
Measure alternating voltage (U), alternating current (I), frequency (F), active power (P), reactive power (Q), power factor (PF) and so on.
Current signal is obtained by the clamp current transformer on line directly
Discern inductive circuit and capacitive circuit;
Directly read differential protection phase among every unit of CT
Can check connection of transformer
Measure two way voltage phase sequence
Can check whether the meter connection is right or not
Can evaluate the running speed of electric kWh meter
High resolution of current, so can be used as a leakage current meter
