All ranges except capacitance & frequency.• Frequency, duty cycle, data hold• Auto power off• Dual display• Built-in test lead storage• Backlit display + Worklight (DL379B & DL389)• Detachable current clamp head (DL379B & DL389)• Temperature (DL379B & DL389)• Magnetic mount (DL379B & DL389)• True RMS measurement (DL389 only)SAFETY NOTESWarningRefer to user guide regarding potential hazard and proper instructions.Before using this meter, read all safety information carefully. In this manualthe word “WARNING” is used to indicate conditions or actions that maypose physical hazards to the user. The word “CAUTION” is used to indicateconditions or actions that may damage this instrument.Warning• Before each use, verify meter operation by measuring a known voltageor current.• Never use the meter on a circuit with voltages that exceed the categorybased rating of this meter.• Do not use this meter during electrical storms or in wet weather.• Do not use the meter or test leads if they appear damaged.• Keep your fingers away from the test lead’s metal probe contacts whenmaking measurements.• Ensure meter leads are fully seated and keep fingers away from metalprobe contact when making measurements. Always grip the leadsbehind the finger guards molded into the probe.• Do not open the meter to replace batteries white the probes areconnected.• Use caution when working with voltages above 60V DC or 25V AC RMS.Such voltages pose shock hazards.• To avoid false readings that can lead to electrical shock, replacebatteries if a low battery indicator appears.• Unless measuring voltage or current, shut off and lock out power beforemeasuring resistance or capacitance.• Always adhere to national and local safety codes. Use proper personalsafety equipment (PPE) to prevent shock and arc blast injury wherehazardous live conductors are exposed.• Always turn off power to a circuit or assembly under test before cutting,unsoldering or breaking the current path. Even small amounts or currentcan be dangerous.• Always disconnect the live test leads before disconnecting the commontest lead from the circuit.• In the event of electrical shock, ALWAYS bring the victim to theemergency room for evaluation, regardless of victim’s apparentrecovery. Electrical shock can cause unstable heart rhythms thatmay need medical attention.• If any of the following occur during testing, turn off the power sourceto the circuit being tested: arching, flame, smoke, extreme heat, smell ofburning materials or discoloration or melting of components.WarningHigher voltages and currents require greater awareness of physical safetyhazards. Before connecting the test leads; turn off power to the circuitunder test; set meter to the desired function and range; connect the testleads to the meter first, then connect to the circuit under test. Reapplypower. If an erroneous reading is observed, disconnect power immediatelyand recheck all settings and connections.WarningThis meter is designed for trade professionals who are familiar with thehazards of their trade. Observe all recommended safety procedures thatinclude proper lock-out utilization and the user of personal protectiveequipment that includes safety glasses, gloves and flame resistant clothing.Symbol DefinitionsEquipment is safe forconnection and disconnectionto Live conductorsGround~ ACAlternating Current Warning or CautionDCDirect CurrentDouble Insulation(Protection Class II)Not Applicable toIdentified Model BatteryCategory DefinitionsMeasurementCategoryShort-Curcuit(typical) kA aLocation in thebuilding installationII < 10 Circuits connected to mains socketoutlets and similar points in theMAINS installationIII < 50 Mains distributions parts of thebuildingIV > 50 Source of the mains installation inthe buildingCONTROLS AND INDICATORSCATIII 600VCATIV300VDISCONNECT TEST LEADS30VTEMPDL379BHi-NCV-Lo MFDμA600V CAT III 400A1. Clamp jaw: Measure inductive AC current. Jaw opens to 1.25” (32mm).2. Wire Separation Tab/NCV Sensor: Used to isolate an individual wirefrom a bundle for testing. NCV sensor helps detect live voltage.3. Conductor Alignment Marks: Used to aid in the visual alignment ofa conductor when measuring inductive amperage. Greatest accuracyis achieved when the conductor, inside the clamp, is centered at theintersection of these marks.4. Test Lead Holder: Used for hands-free use of one of the test probes.5. Hand Guard: Used as a point of reference for the operator’s safety.WarningAlways keep your hands and fingers behind the hand guards whenmeasuring current on exposed conductors. Contact may result in seriousinjury.6. Clamp Lever: Opens and closes current clamp jaw.NOTE: The clamp uses a high-tension spring to close the jaw. Do notallow fingers or objects to become pinched in the hinge as jaws close.7. NCV (Non-Contact Voltage) Button: Activates non-contact voltagefunction. Dual level indication on DL379B only.8. Range Button: Used to select range for upper and lower displayreadings.9. Hold/Backlight Button: Freezes readings or activates backlight andworklight. (Worklight available on DL379B and DL389)10. Min/Max Button: Activates MIN/MAX capture function, cycles throughminimum and maximum values. Press and hold for 2 seconds to return tolive readings.11. Rotary Function Switch: Turns meter on and is used to select the rangeor function.12. Upper Display: Used to display current when measuring with the clamphead, or UEi’s optional current hook adapter. Displays output from otheraccessories when connected to UEi’s meter base.13. Lower Display: Used to display input to test lead jacks. Includes AC/DC volts, frequency, resistance, diode, capacitance and AC/DCmicroamps (μA).14. Select Button: Used to choose a measurement mode from selectionswith multiple options such as AC or DC volts; AC or DC microamps;resistance, diode, capacitance or continuity; Fahrenheit or Celsius.15. Temperature Input Jack: Input jack for K-type thermocouple probe(available on DL379B and DL389).16. Temperature Input Jack Lock: Move switch down to measuretemperature.NOTE: Test leads must be removed from input jacks prior to operatingthe temperature function.17. Hz/Duty Cycle Button: Used to toggle between frequency and duty cyclewhen in AC voltage measurement mode.18. Common Terminal: The black test lead is plugged into this input jack tosupply ground or “low” reference for all measurements.19. Maximum Category Indicator: Indicates maximum voltage for the ratedworking category.WarningDO NOT exceed 1000V DC or AC RMS at either the common ormultifunction input jacks as measured from earth ground.20. Multifunction Input Jack: Used for measuring AC/DC volts, frequency,duty cycle, resistance, diode, continuity, and capacitance.WarningUse CAT III listed test leads or higher. DO NOT attempt to measure morethan 1000V DC, 750V AC or 2000μA DC.Displays and IndicatorsLocation of function icons on display may vary be model number.~ AC indicatorDC indicator- Indicates a negative value (DC negative voltage)MAX Maximum value displayedMIN Minimum value displayedA (top display) Displaying Amps from clamp jaw or adapterADP (top display) Displaying value from adapterLow battery indicationHOLD Hold functionDiode functionContinuity functionnF / μF Capacitance function (nanofarads or microfarads)nA Microamps function (1μA is 0.000001 Amp)Hz Frequency function% Duty cycle functionmV Millivolts function (1 mV is 0.001 Volt)APO Auto power off is activeAT Auto Range mode is activeO.L.
