Operation
AC/DC VOLTAGE MEASUREMENTS
CAUTION: Do not measure AC/ DC voltages if a motor
on the circuit is being switched ON or OFF. Large
voltage surges may occur that can damage the meter.
1.
Set the function switch to the green V position.
2.
Press the MODE button to indicate "DC" or "AC" on the
display.
3.
Touch the black test probe tip to the negative side of
the circuit.
Touch the red test probe tip to the positive side of the
circuit.
4.
Read the voltage in the display
DC/AC CURRENT MEASUREMENTS
1.
Set the function switch to the µA/mA position.
2. For current measurements up to 4000µA DC/AC, set the
function switch to the mA position
3.
Press the MODE button to indicate "DC" / "AC" on the
display.
4.
Remove power from the circuit under test, then open up
the circuit at the point where you wish to measure
current.
5.
Touch the black test probe tip to the negative side of
the circuit.
Touch the red test probe tip to the positive side of the
circuit.
6.
Apply power to the circuit.
7.
Read the current in the display
NOTE: 0.2A/500V fast acting Resettable Fuse
current inputs and Overload protection on mA, µA
ranges. No replacement required.
RESISTANCE MEASUREMENT
WARNING: To avoid electric shock, disconnect power to
the unit under test and discharge all capacitors before
taking any resistance measurements. Remove the
batteries and unplug the line cords.
1. Set the function switch to the Ω
2. Press the MODE button to indicate on the display.
Touch the test probe tips across the circuit or part under
3.
test. It is best to disconnect one side of the part under
test so the rest of the circuit will not interfere with the
resistance reading.
4. Read the resistance in the display
CONTINUITY CHECK
WARNING: To avoid electric shock, never measure
continuity on circuits or wires that have voltage on them.
1. Set the function switch to the Ω
2. Press the MODE button to indicate on the display
3. Touch the test probe tips to the circuit or wire you wish to
check.
4. If the resistance is less than approximately 150, the
audible signal will sound. If the circuit is open, the
display will indicate "OL".
DIODE TEST
1. Set the function switch to the Ω
Press the MODE button to indicate
2.
display.
Touch the test probes to the diode under test. Forward
3.
voltage will typically indicate 0.400 to 0.700V. Reverse
voltage will indicate "OL". Shorted devices will indicate
near 0V and an open device will indicate "OL" in both
polarities
Capacitance Measurement
WARNING: To avoid electric shock, disconnect power to the unit
under test and discharge all capacitors before taking any
capacitance measurements. Remove the batteries and unplug
the line cords. Never measure continuity on circuits or wires that
have voltage on them.
1.
Set the function switch to the " Ω
2.
Press the SELECT button until "nF" appears in the display.
3.
Press the RELATIVE button to zero the display
4.
Connect the test leads to the capacitor to be measured.
5.
Read the value on the display.
Frequency/Duty Cycle Measurement
1. Set the function switch to the "HZ/DUTY" position.
2. Press the Hz/DUTY button once to display Duty Cycle %. Pressing
the button again will toggle the display to frequency (Hz).
3. Touch the test probe tips to the circuit under test. Be sure to
observe the correct polarity (red lead to positive, black lead to
negative).
4. Read the value on the display.
Non-Contact AC Voltage Measurements
WARNING: Risk of Electrocution. Before use, always
test the Voltage Detector on a known live circuit to
verify proper operation
1. Touch the probe tip to the hot conductor or insert into the
hot side of the electrical outlet.

twisted. For best results, rub the probe tip along a
length of the cord to assure placing the tip in close
proximity to the live conductor.
Static electricity or other sources of energy may
randomly trip the sensor. This is normal operation
Flashlight
Press and hold the top button to turn the flashlight on.
Release the button to turn the flashlight off.
AUTO POWER OFF
The auto off feature will turn the meter off after 15 minutes.
REPLACING THE BATTERY
1. Remove the bottom cover and secure the screw.
2. Replace old battery with fresh
