Battery Digital Elcb Tester

The RCB Tester is a microprocessor-controlled instrument designed for accurate and reliable testing of residual current devices (RCDs). Featuring a clear 2-line × 16-character LCD display, it allows users to view test parameters and results simultaneously. The tester includes an automatic data hold function and zero-crossing circuitry for precision testing at 0° and 180°, ensuring dependable results under varying test conditions.

With selectable current ranges from 3 mA to 375 mA, it is suitable for testing a wide variety of RCDs. The device also measures voltage and frequency between line and earth before conducting a test, adding an extra layer of safety and convenience. Compact and battery-powered, it is ideal for field and workshop use.
