MANUALLY SETTING THE RANGE

When you measure voltages or resistance, your meter
can automatically select a measuring range. When you
measure current, the meter automatically selects a range
within the limits of the selector's setting. While this fea-
ture is convenient, it might be faster to manually set the
range when measuring values that you know are within a
certain range.
To switch to manual-range control, press . RH
RANGE
(Range Hold) appears on the display and the meter holds
the range at its current setting. Repeatedly press

hold for about 1 second. RH disappears from the
RANGE
display and the meter automatically selects the range
that gives the best reading.
