‘CY-RAM2000 parallel-cables current balance detector’ is designed for easy installation in a small space without removing the main bus or cable. It consists of two parts: flexible rogowski coil probe and electronic modules with a display.The instrument can simultaneously display two wires AC current, and also shows the current difference & current unbalanced degree between two wires. Mainly used for various power bus current measurement, and two current balance detection.
Features：
Flexible,lightweight, beautiful appearance
Simple and quick installation in small space
without high voltage in secondary open circuit
No iron core saturation and damage when overload
Excellent linearity
Multi-size optional
Application：
General measurement and protection for strong mobility or space-constrained or uninterrupted power systems
Power instrumentation, electronic multi-function energy meter and field calibrator, instrumentation measurement and protection
E.g.
parallel-cables bus current balance detection
Three-phase load current balance detection of power system;
Current detection of large load power system lines.

⑦Hold button : data hold key, short press to keep the current data, press again to return to normal;
⑥B/L button: short press to turn on or off the LCD backlight, long press debug two channels for the same value.
Usage instruction：
Attention:
1. To achieve best accuracy, flexible rogowski coil measurement probe should keep consistent with A, B channel when connection.
2. When the display shows low power, display dim, can not boot, you should replace the battery.
3 When the display is not normal (e.g. only two lines are displayed), remove the battery and reload it.
