8978
Digital Loop/PSC Tester c/w RCD-LOC

Loop testing without tripping out any type of RCD. The unique 5
mA test current means the unit will not overheat. The 8978 is the
fastest non trip loop tester on the market
The resistance of the individual conductors can be measured with
a single press of the test button, enabling R1 & R2 values to be
established on live circuits.
The unique RCD-LOC feature allows loop testing without tripping any type of RCD. The 8978 meets all the safety and performance requirements of BS EN 61557.
Features;
- Will test in the presence of any type RCD > 30mA,
with a resolution of 0.01 ohm - Direct readout of Prospective Short Circuit Current
- Enables the measurement of the individual conductor
resistances independently - Includes an auto power off to ensure optimum battery usage
- Measure AC voltages up to 300 V AC
- Fully compliant with safety standards: IEC1010, EN61557,
BS7671 and Part P
