Hi-Z Dcv, Acv & Line-Level Hz Functions - Amprobe ACD-15 Pro Manual De Uso

Hi-Z DCV, ACV & Line-Level Hz functions
Set the slide-switch function selector to the position that selects common
impedance (Hi-Z) voltage measurements. Input impedance is set at
approximately 5MΩ to minimize loading on circuits under tests. DCV is
the default function. The DC symbol "�" appears. Press SELECT button
momentarily to select ACV. The AC symbol "�" a ppears. Press momentarily
again to activate the Line-Level Hz function.
Note:
• Line-Level Hz input sensitivity varies automatically with ACV range selected
when Line-Level Hz is selected. AC 6V range has the highest and AC 600V
range has the lowest sensitivity. Measuring the signal in ACV function WHILE
selecting Line-Level Hz function in that ACV range automatically sets the
most appropriate sensitivity for higher voltage applications. This can avoid
electrical noises as in 110/220V line voltage applications for example. If the
reading shows zero due to insufficient signal levels, select Line-Level Hz
function BEFORE making measurements (at AC 6V range) will set the highest
sensitivity.
