Zoom Mode (Power Up Option Only)
To use the Rel Zoom Bar Graph:
Hold down F while turning the Meter on. The
1.
display reads "2rEL".
Select the relative mode by pressing F
2.
again.
3.
The center of the bar graph now represents zero
and the sensitivity of the bar graph increases by
a factor of 10. Measured values more negative
than the stored reference activate segments to
the left of center; values more positive activate
segments to the right of center.
Uses for the Zoom Mode
The relative mode, combined with the increased
sensitivity of the bar graph's zoom mode, helps you make
fast and accurate zero and peak adjustments.
For zero adjustments, set the Meter to the desired
function, short the test leads together, press
connect the leads to the circuit under test. Adjust the
circuit's variable component until the display reads zero.
Only the center segment on the zoom bar graph is lit.
For peak adjustments, set the Meter to the desired
function, connect the leads to the circuit under test; then
F
press
. The display reads zero. As you adjust for a
positive or negative peak, the bar graph length increases
to the right or left of zero. If an overange symbol lights
(< >), press
continue with the adjustment.
HiRes Mode
Pressing H for one second causes the Meter to enter the
high-resolution (HiRes), 4-1/2 digit mode. Readings are
displayed at 10 times the normal resolution with a
maximum display of 19,999 counts. The HiRes mode
works in all modes except capacitance, frequency counter
functions, temperature, and the 250 s (peak) MIN MAX
modes.
To return to the 3-1/2 digit mode, press H again for one
second.
