11.5 LoZ voltage mode
LoZ mode allows you to measure DC and AC voltages with a low impedance (ap-
prox. 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 measurement mode.
To enable LoZ mode, press the "LoZ" button when taking a voltage measurement.
The impedance will be reduced until you release the button. In the LoZ mode, a
beep sounds and the display (B) is indicated.
The "Loz" symbol (C9) appears on the display.
The LoZ mode can only be used for circuits with a voltage of up to
1000 V. The duration of the LoZ measurement must be limited to a
maximum of 3 s.
After using the LoZ mode, leave the multimeter for 1 minute before
using it again.
11.6 Taking current measurements
Never exceed the maximum permitted input values. Never touch
circuits or parts of circuits when they may contain voltages greater
than 33 V/ACrms or 70 V/DC! Danger to life!
The voltage in the measured circuit must not exceed 1000 V.
Measurements greater than 10 A must only be made for a maximum
of 10 seconds in 10-minute intervals.
Always start the current measurement using the largest measure-
ment range, and then switch to a smaller range if necessary. Always
disconnect the circuit before connecting the multimeter and chang-
ing the measurement range. All current measurement ranges are
protected against overload.
Do not measure any currents above 10 A in the A range or currents
above 600 mA in the mA/μA range, as this will trigger the fuses.
