E&$*- Remove plugs from
ends of Test Leads (included)
before connecting to Meter.
E&$*- Test Lead probes have removable
covers for overvoltage protection. With
covers in place, Test Leads are rated for
use with CAT IV circuits. Exposed probes
are rated for use with CAT II circuits.

Measure AC conductors carrying
up to 1000 VAC, 40-400 Hz.
Measure DC conductors
carrying up to 1000 VDC.
R@;ECESb Use caution when working
near voltages above 30 VAC rms,
42 VAC peak, or 60 VDC. Voltages this
high present a risk of electric shock.
1. Plug black test lead into QVD Jack.
Plug red test lead into C8/'$ Jack.
2. Turn Rotary Switch to the %position.
3. Press <FEQ button to choose
between AC and DC voltage.
4. Carefully touch exposed
conductors with tips of probes.
5. Read measured voltage on the
Display. For AC voltage, frequency
is shown at the top right.
Use the G&Ke switch position on
Meter when readings are suspect
(ghost or stray voltages may
be present), or when testing for
the presence of voltage. Follow

Measure frequency up to 66MHz.
1. Plug black test lead into QVD Jack.
Plug red test lead into C8/'$ Jack.
2. Turn the Rotary Switch to
the Ba_%position.
3. Connect the Test Leads across
the circuit to be measured.
4. Read measured frequency in
the center of the Display. Duty
cycle is shown at the top right.
5. When testing is complete, turn
Rotary Switch to V<<I remove
