305 BK Precision Insulation Meter
- Test insulation resistance
- Measure AC voltage to 600V
- Battery powered
- 500V test voltage
- Test up to 1000M ohms
The BK Precision 305 500 V / 1000 M Megohmeter insulation tester is intended primarily for periodic testing of industrial motors, transformers, electrical wiring, and cable insulation for signs of deterioration.
Low readings may indicate impending failure allowing for permit replacement of suspect component during routine maintenance rather than risking component failure.
The Bk 305 is also useful for safety testing of TV sets and appliances to assure no hazardous leakage current. The voltage and resistance ratings for insulation testing are often specified for the product to be tested.
