Product Description
GF211BMulti-function Double Clamp Digital Phase Angle Meter
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.
1. Can check connection of transformer
2. Measure two way voltage phase sequence
3. Discern inductive circuit and capacitive circuit
4. Can check whether the meter connection is right or not
5. Can evaluate the running speed of electric kWh meter
6. Directly read differential protection phase among every unit of CT
7. Hhigh resolution of current, so can be used as a leakage current meter
8. Current signal is obtained by the clamp current transformer on line directly
9. Measure phase angle between two voltages, between two current or between voltage and current
10. Measure alternating voltage (U), alternating current (I), frequency (F), active power (P), reactive power (Q), power factor (PF) and so on
