DC voltage measurement
Procedure
1. Set the rotary switch of the device to switch position “Hz
” or “Volt Sense / Lo‑Z Auto‑V”.
– “Hz
”: Press the “AC HFR / DCA ZERO” key to set the desired measuring function
(frequency, AC or DC voltage).
– “Volt Sense / Lo‑Z Auto‑V”: The corresponding measuring function (AC or DC voltage)
and the optimum measuring range are set automatically. The input resistance is
reduced to approx. 3 kΩ in order to suppress inductive and capacitive voltages (reactive
voltages).
2. Connect the safety measuring lines to the device [
3. Bring the safety measuring lines into contact with the measuring points and read the
measured value on the digital display.
