To avoid equipment damage when using the HiV function make sure
that circuits or components connected to the Multimeter can withstand
at least 240 V dc.

Provides selection of the resolution for subsequent readings.
Controls a single-pole analog filter for increased noise rejection.
The Filter annunciator on the left-hand display indicates that the filter is
active.
The pole or time constant of the filter is formed by a Capacitance
of 22 nF across the resistor under test.
Select a higher read rate. This will result in an increase in uncertainty due
to noise.
Selects 4-wire resistance measurements in which the stimulus current is
fed through the test resistance from the instrument's
terminals. The resulting potential difference is sensed by the
and terminals. Otherwise all measurements are 2-wire, current being
