‘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.

Button function:
⑧Power button: switch key, long press more than 3 seconds turn on/off;
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.
