SAFETYOPERATIONMAINTENANCE SETUP
Resistance Measurement
WARNING! TO PREVENT SERIOUS
INJURY: To prevent electric shock, turn off
all power and fully discharge capacitors on
the circuit under test before measuring.
Note: When measuring Ohms,
start with the lowest range if the
resistance is unknown.
1. Plug black test lead into COM Jack.
Plug red test lead into INPUT Jack.
2. Turn Rotary Switch to the position.
3. Press MODE until Ω is displayed.
4. Carefully touch exposed
conductors with tips of probes.
5. Read measured resistance
on the Display.
6. When testing is complete, turn
Rotary Switch to OFF, remove
Test Leads and store with Meter.
Note: Sometimes resistor value and
measured resistance differ. This is due
to the Meter’s output test current going
through all possible paths between leads.
Note: For low resistance measurements,
short the test leads and record the
resistance displayed. Then connect to
the circuit and subtract the recorded
resistance from the measurement
for the most accurate results.
AC NCV (Non-Contact Voltage)
1. Turn Rotary Switch to the position.
2. Move the tip of the clamp close
to the unshielded conductor.
3. If AC voltage is present, the LCD will
display 1 to 3 dashes, Meter will beep
and the Non-Contact Voltage Indicator
will flash. The higher the AC voltage,
the more dashes that will be displayed.
Thicker wire insulation, and different
power outlets will give lower reading.
WARNING! TO PREVENT SERIOUS
INJURY: Even if no indication is given,
voltage may still be present.
Do not rely solely on NCV detection to
determine the presence of voltage.
