User manual

Proceed as follows to measure alternating “V ” (AC) voltages:

- Switch the DMM on and select the “V ” measurement

mode.

- Press the “SELECT” (I) button on the rotary control to switch to

“AC” mode. “TRMS, “AC” and “V” will appear on the display.

- For lower voltages up to max. 600 mV, select the “mV ”

measurement range. Press the “SELECT” (I) button on the

rotary control to switch to “AC” mode. “TRMS”, “AC” and the

unit “mV” will appear on the display.

- Insert the red lead into the V socket (G) and the black lead into

the COM socket (H).

- Connect the two measuring probes to the object that you want

to measure (e.g. generator or circuit).

- The measurement will appear on the display.

- After taking a measurement, remove the leads from the meas-

ured object and switch the DMM off.

d) LoZ voltage mode

LoZmodeallowsyoutomeasureDCandACvoltageswithalowimpedance(approx.400kΩ).Inthismode,the

multimeter lowers the internal resistance to prevent phantom voltage readings. As a result, the circuit is more heavily

loaded than in the standard measuring mode.

InordertouseLoZmeasurementmode,pressthe“Lowimp.400kΩ”button(J)duringvoltagemeasurement.The

measured impedance is reduced for as long as the button is pressed.

“LoZ” (B20) will appear on the display.

LoZ measurement mode may only be used up to a maximum voltage of 250 V. The duration of the LoZ

measurement must be limited to a maximum of 3 s. This mode is not available in the mV measurement

range.

After using LoZ mode, leave the multimeter for 1 minute before using it again.
