Use the LOADpro* with your meter to find these problems FAST:* High Corrosive Resistance* Shorts to ground* Open CircuitsLOADpro* performs voltage drop Applications * Automotive * Heavy Duty * Marine * RV Equipment LOADpro* performs voltage drop test with the push of a button. Voltage drop has never been this simple! LOADpro* works with your existing DMM. Connect the LOADpro* to your with your DMM. Then connect the LOADpro* to a 12 Volt system, press the LOADpro* switch to apply a load of approximately 0.5 Amps across the circuit. This simple test finds problems in corroded wires/connections and shorts to ground. Watch the LOADpro* video to see how it helps you diagnose faster and earn more $$$ diagnosing wiring problems.
