With the T6 electrical tester, you can also carry out measurements where this was previously impossible by measuring voltage and current through the fork opening. You can measure (not just detect) the voltage without making contact with a live wire. This means: Simultaneous measurement of voltage and current with True RMS, Measurement in a very small space as no test leads need to be used, Time saving as no touch protection covers and cable connections need to be removed to carry out the measurements, Measurements with just one hand, Reduction of the risk of electric shock and arc flash
