Safety
• Do not exceed the maximum allowable input range of any function
• Do not apply voltage to the meter when resistance function
is selected
• Set the function switch OFF when the meter is not in use
Warning
• Set the function switch to the appropriate position before measuring
• When measuring volts do not switch to current/resistance modes
• When changing ranges using the selector switch always disconnect
the test leads from the circuit under test
• Do not exceed the maximum rated input limits
Caution
• Improper use of this meter can cause damage, shock, injury or death
• Read and understand this user manual before operating the meter
• Always remove the test leads before replacing the battery
• Inspect the condition of the test leads and the meter itself for any
damage before operating
• Repair or replace any damage before use
• Use great care when taking measurements if the voltages are greater
than 25VAC RMS or 35VDC as they are considered a shock hazard

Operating Instructions
AC Current Measurements
1. Set the function switch to the 400
or 40A range. If the range needed
is not known, select the higher
range rst then move to the lower
range if necessary.
2. Press the trigger to the open jaw
and fully enclose one conductor.
The LCD will display the reading.
AC/DC Voltage Measurements
1. Insert the black test lead into the negative COM terminal and the
red test lead into the positive V terminal.
2. Set the function switch to the V position, and select either AC or
DC with the MODE button.
3. Connect the test leads in parallel to the circuit under test.
The LCD will display the reading.
Resistance Measurements
1. Insert the black test lead into the negative COM terminal and the
red test lead into the positive V terminal.
2. Set the function switch to the Ω position.
3. Touch the test probe tips across the circuit or component under
test. It is best to disconnect one side of the device under test so
the rest of the circuit will not interfere with the reading.
4. The LCD will display the reading.

Diode and Continuity Measurements
1. Insert the black test lead into the negative COM terminal and the
red test lead into the positive V diode terminal.
2. Turn the rotary switch to the Ω position. Press the MODE button
until the Diode Test indicator appears on the display.
3. Touch the test probes to the diode under test. Forward voltage will
indicate 0.4V to 0.7V. Reverse voltage will be indicated by “OL”.
Shorted devices will indicate near 0mV and an open device will
be indicated by “OL” in both polarities. For Continuity tests, if the
resistance is < 150, a tone will sound.
Capacitance Measurements
1. To avoid electric shock, disconnect power to the unit under test
and discharge all capacitors before taking any capacitance mea-
surements. Remove the batteries and unplug the line cords.
2. Set the rotary function switch to the CAP position.
3. Insert the black test lead into the negative COM terminal and the
red test lead into the positive V terminal.
4. Touch the test leads to the capacitor to be tested. Read the
capacitance value on the display.
Frequency or % Duty Cycle measurements
1. Set the rotary function switch to the V position.
2. Insert the black test lead into the negative COM terminal and the
red test lead into the positive V terminal.
3. Select Hz or % duty with the Hz/% button.
4. Touch the test probe tips to the circuit under test. Read the
frequency value on the display.

Temperature Measurements
1. To avoid electric shock, disconnect both test probes from any
source of voltage before making a temperature measurement.
2. Set the function switch to °C or °F.
3. Insert the Temperature Probe into the negative COM and the posi-
tive V terminals, making sure to observe the correct polarity.
4. Touch the Temperature Probe head to the area to be measured.
Keep the probe touching the part under test until the reading stabi-
lizes (about 30 seconds).
5. Read the temperature value on the display. To avoid electric shock,
be sure the thermocouple has been removed before changing to
another function.
Non-Contact AC Voltage Measurements
1. Touch the probe tip to the hot conductor or insert into the hot side
of the electrical outlet. If AC voltage is present, the detector will
light up.
2. The conductors in electrical cord sets are often twisted. For best
results, rub the probe tip along a length of the cord to assure plac-
ing the tip in close proximity to the live conductor.
3. The detector is designed with high sensitivity. Static electricity or
other sources of energy may randomly trip the sensor.
Data Hold
While taking a measurement, press the Data Hold button to freeze the
display. The HOLD indicator will also appear on the display. Press the
Hold button again to resume measuring.
Relative Mode
Press the REL button for Capacitance Zero & Offset Adjustment.
