Resistance Measurements / Continuity

�
D isconnect the UUT from all sources of supply and check that it is at
zero voltage.
1) Turn selector switch (2) to Ω / R
2) Plug the black test lead into the "COM" socket and the red lead into
the "+" terminal
3) Connect the probes to the UUT and read the display
If the display is not visible during measurement, press the "HOLD"
button (3) to retain the display. The probes can then be removed from
the conductor and the stored value read.
Continuity: At a resistance between ≤ 10 Ω and > 38 Ω a signal is audible.

MIN/MAX and peak values/ Auto Power Off

The MIN/MAX button can be used to find the largest and the smallest value
of a series of measurements. Press the button to toggle between MAX and
MIN values. Press and hold the button for 2 seconds to exit this function. The
MAX/MIN is not available in the Continuity and Hz function.
Pressing it a second time changes to MAX mode, for the largest value.
Pressing the button a third time returns the instrument to normal
operation.
