• If a more accurate measurement is
desired, select the proper. Resistance range
using the RANGE button.
Insert:
• Black lead in COM jack.
• Red lead in RPM, V, Ω jack.
-Touch the test lead probes across the
resistance or circuit to be tested.
Accuracy:
Rapidly changing display readings (noise)
can sometimes be eliminated if you change
to a higher range.
Continuity Test.
A DMM with a continuity beeper allows
you to quickly and easily distinguish
between an open and a closed circuit.
The Meter beeps when it detects a closed
circuit or short, so you do not have to look
at the Meter during the test. This can be
a valuable troubleshooting aid when
determining: good or blown fuses and
fusible links, open or shorted conductors
and wires, the operation of switches, etc.

NOTE: Turn the power off to the circuit
to be tested. A beeper tone does not
necessarily mean zero resistance.
To test circuit continuity:
• Select the Ω /
switch and press the DC/AC button to

The symbol appears on the display and
the Meter defaults to the 400Ω range.
Insert:
• Black lead in COM jack.
• Red lead in RPM, V, Ω jack.
Connect one test probe to each end of the
circuit to be tested:
• If circuit is closed, the Meter will
beep @ < 100Ω
• If circuit is open, there is no beep.
RPM Measurements Using the
Inductive Pickup.
Pickup RPM refers to revolutions per
minute. Using the inductive pickup,
