If the pointer does not normally rest exactly over “O” at the
left side of the scale, adjust the plastic screw in the lowest
center of the meter face to bring the pointer to “O”

For most accurate readings, keep the meter lying flat on a
non-metallic surface. Also, use a range and range doubler
switch setting that results in a reading in the upper 1/3rd of
To read the scale, look at it from the point where the pointer
and its reflection in the mirror come together; otherwise,
the parallax will cause an error in the reading.

Using Test Leads
Setting up Your Meter
Use only the same type of test leads as are supplied with
your unit. These test leads are rated for 1200 volts;
replacements are available from your local Radio Shack
store. (Cat. No. 278-704)
CAUTION: Although these test leads (Cat.No.278-704) are
rated for 1200V, the maximum rating of this meter is
1000V. You should not attempt to measure any voltage
greater than 1000V.
Always observe correct test lead polarity when making DC
measurements: The black lead should always be connected
to the © COM jack. Connect the red lead to@ (@ V-2-A)
for making DC measurements up to 250V, DC current up to
500mA, all AC voltage and resistance measurements;
connect it to ® (GDC 1000V) when measuring DC voltage
from 250V to 1000V; and connect it to © (@ DC 10A)
when measuring DC current from 500mA to 10A.
NEVER ALLOW YOUR FINGERS TO TOUCH THE BARE
METAL PART OF THE TEST PROBES (OR CIRCUIT
POINTS).
For safety’s sake, disconnect the leads from the circuit
under test as soon as you have completed measurements.
