International Safety Symbols
This symbol, adjacent to another symbol or terminal, indicates the user must refer to the manual for further information.
This symbol, adjacent to a terminal, indicates that, under normal use, hazardous voltages may be present

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
• Set 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.
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 25V AC rms or 35V DC. 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difcultandmisleadingbecauseoftheuncertaintyofconnectiontothere-
cessed electrical contacts. Other means should be used to ensure that the terminals are not “live”.
• Iftheequipmentisusedinamannernotspeciedbythemanufacturer,theprotectionprovidedbytheequipmentmaybe
impaired.

Operation
NOTICES: Read and understand all warning and precaution statements 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 or 40A range
2.Iftherangeofthemeasuredisnotknown,selectthehigherrangerstthen
move to the lower range if necessary.
3.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.
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.
Resistance 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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 resistance reading.
4. For Resistance tests, read the resistance on the LCD display.
Diode and Continuity 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 Ω 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.
For Continuity tests, if the resistance is < 150, a tone will sound.

Capacitance Measurements
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.
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
Frequency or % duty cycle measurements
1. Set the rotary function switch to the “V DC/AC,Hz” position.
2. Insert the black lead banana plug into the negative COM jack and the red test lead banana plug into the positive V jack
3. Select Hz or % duty with the Hz/% button.
4. Touch the test probe tips to the circuit under test.
5. Read the frequency on the display.
Temperature Measurements
WARNING: To avoid electric shock, disconnect both test probes from any source of voltage before making a temperature
measurement.
1. Set the function switch to °C or °F.
2.InserttheTemperatureProbeintothenegative(COM)andtheVjacks,makingsuretoobservethecorrectpolarity.
3.TouchtheTemperatureProbeheadtothepartwhosetemperatureyouwishtomeasure.Keeptheprobetouchingthepart
under test until the reading stabilizes (about 30 seconds).
4. Read the temperature in the display. The digital reading will indicate the proper decimal point and value.
WARNING: To avoid electric shock, be sure the thermocouple has been removed before changing to another measurement
function
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.
2. If AC voltage is present, the detector light will illuminate.
NOTE: The conductors in electrical cord sets are often 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.
NOTE: The detector is designed with high sensitivity. Static electricity or other sources of energy may randomly trip the sen-
sor. This is normal operation
