G.L McGavin have been manufacturing High & Low voltage testers since 1975. The new G.L McGavin Digital hand held Proximity Tester FR30 is designed for Electricians, Technicians and the Fire & Rescue departments.For electricians it can be used for picking up live wires behind walls, identifying live cables and tracing live cable runs. For the Fire & Rescue it is used for the safety of the rescue personnel in situations where live voltage can be present impeding rescue operations. Because it is a Digital device it can be programmed to suit any application.
When the unit is activated using the ON switch the unit will self test automatically ensuring the unit is in working order. The Self Test button is located on the front face of the tester. This is a full function test of all components of the unit testing:
The self test button is recommended to be used at regular intervals during the working day. In the event the tester fails please refer to (Service and trouble shooting).
The Self Test feature is designed as an independent circuit, apart from the detection circuit. This Self Test circuit produces an AC signal that the detection circuit can pick up, as it would pick up an outside signal source. This allows confidence The Rescue FR30 is working correctly.
