SAFETY NOTES
· Do not exceed the maximum allowable input range of
any function
· Do not apply voltage to meter when resistance function
is selected.
· Set the function switch OFF when the meter is not in use.
WARNINGS
· The dial must be set to the OFF position when installing the
batteries, or there will be no display until the dial is returned
to OFF to reset the meter.
· Set function switch to the appropriate position before
measuring.
· When measuring volts do not switch to current/resistance
modes.
· Do not measure current on a circuit whose voltage
exceeds 240V.
· 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.
CAUTIONS
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 the meter. Repair or
replace any damage before use. Use great care when making
measurements if the voltages are greater than 25VAC rms or
35VDC. These voltages are considered a shock hazard.
Remove the battery if the meter is to be stored for long periods.
Always discharge capacitors and remove power from the device
under test before performing Diode, Resistance or Continuity tests.
· Voltage checks on electrical outlets can be difficult and
misleading because of the uncertainty of connection to the
recessed electrical contacts. Other means should be used to
ensure that the terminals are not “live”.
· If the equipment is used in a manner not specified by the
manufacturer, the protection provided by the equipment
may be impaired.

Operation
NOTICES: Read and understand all warning and
precaution listed in the safety section of this operation
manual prior to using this meter. Set the function select
switch to the OFF position when the meter is not in use.
AC Current Measurements
WARNING: Ensure that the test leads are disconnected
from the meter before making current clamp measurements.
1.Set the Function switch to the 400 or40A or 4A range.
If the range of the measured is not known, select the
higher range first then move to the lower range if
necessary.
2. Press the trigger to open jaw. Fully enclose one
conductor
to be measured.
The clamp meter LCD will display the reading.
DC/AC 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.
etc., with
transient overvoltages less than Overvoltage Cat. III
3. Select AC or DC with the MODE button.
4. Connect the test leads in parallel to the circuit under test.
5. Read the voltage measurement on the LCD display.
µA DC/AC CURRENT MEASUREMENTS
1. Insert the black test lead into the negative COM terminal and the
red test lead into the positive µA terminal.
2. Set the function switch to the µA position.
3. Select AC or DC with the MODE button.
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 display.
Resistance and Continuity Measurements
1. Insert the black test lead into the negative COM
terminal and the red test lead into the positive terminal.
2. Set the function switch to the •))) position.
3. Use the multifunction MODE button to select resistance.
4. 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 resistance reading.
5. For Resistance tests, read the resistance on the LCD display.
6. For Continuity tests, if the resistance is < 100, a tone will
sound.
Diode Measurements
1. Insert the black test lead banana plug into the negative COM jack
and the red test lead banana plug into the positive diode jack.
2. Turn the rotary switch to the •))) position.
3. Press the MODE button until “ “ appears in the display.
4. Touch the test probes to the diode under test. Forward voltage will
indicate 0.4V to 0.7V. Reverse voltage will indicate “OL”. Shorted
devices will indicate near 0mV and an open device will indicate
“OL” in both polarities.

Forward test Reverse test
Capacitance Measurements
WARNING:
To avoid electric shock, disconnect power to the unit
under test and discharge all capacitor before taking any capacitance
measurements. Remove the batteries and unplug the line cords.
1. Set the rotary function switch to the cap position.
2. Insert the black test lead banana plug into the negative (COM) jack.
Insert the red test lead banana plug into the positive (V) jack.
3. Touch the test leads to the capacitor to be tested.
4. Read the capacitance value in the display
