5.4.2‘LoZ’VoltageMeasurements
Whenthefunctionswitchisturnedtothe position,themeterincorporatesalow
impedancecircuitthateliminatesghostvoltages.Thelowimpedanceisapprox.2.5kΩ.Totake
voltagemeasurementsintheLoZmode,selectthe
functionswitchpositionandfollowthe
voltagemeasurementinstructionsintheprevioussection.
