307A CAL D

The 307A CAL D from B&K Precision is an analogue insulation & continuity meter. Insulation is necessary for every electrical apparatus and installation needs to be safe for the user and for the equipment itself. The 307A 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. It 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. It also checks the continuity of wires, complete circuits, connections, closure of contacts, circuit breakers, fuses, bounding resistance of connections to ensure wire integrity.
