WARNING
To avoid electrical shock while manual ranging use the
display annunciators to identify the actual range selected.
Correcting an Overload (
0o
or -
0o
) Indication
�
An
0o
or -
0o
indication may appear on the display to indicate
that an overload condition exists. For voltage and current
measurements, an overload should be immediately corrected
by selecting a higher range. If the highest range setting does
not eliminate the overload, interrupt the measurement until
the problem is identified and eliminated. The
0o
indication
is normal for some functions; for example, resistance,
continuity, and diode test.
Measuring DC Voltage
1. Set the Function Switch to
v
.
2. If
RANGE
is displayed, press the
RANGE
button to
enable autoranging.
3. Connect the Test Leads: Red to
E
, Black to
COM
4. Connect the Test Probes to the circuit test points.
5. Read the display, and, if necessary, correct any
overload (
0o
) conditions.
