7822
Multi-Function Automotive Tester
With colour screen and power probe functions
An innovative and useful multi-function tool that tests for voltage, current,
resistance, continuity, short circuits, signal frequency and bad earths.
It is also a power-probe, suitable for energizing components on or off the
vehicle. Powers up components prior to fitting: relays and bulbs, etc.
Tests continuity in switches, relays, fuses and wiring looms; tests polarity
on cables and sockets.
Powered by the vehicle's own 12-24 volt DC power supply and complete
with 2.0m cable. Kit also includes 6.0m extension cable.
Accessories include extra-long probe, wire-piercing probe and
