• Comparing to online power quality analyzer, E6000 handheld type with small size, light weight, easy for the engineer to carry and carry out to survey work whenever and wherever.

 • Easy to wiring

 • It can operate directly to the line under test under the circumstances that the Power Grid without interrupt.

 • Multi-range current switching

 • based on actual demand, the different range of current clamp can be replaced to improve measurement accuracy.

Applications

Frontline troubleshooting - quickly diagnose problems on-screen to get your operation back online
Predictive maintenance - detect and prevent power quality issues before they cause downtime
Quality of service compliance - validate incoming power quality at the service entrance
Long-term analysis - uncover hard-to-find or intermittent issues
Load studies - verify electrical system capacity before adding loads
Energy assessments - quantify energy consumption before and after improvements to justify energy saving devices.
