PROFESSIONAL AUTO-RANGING DIGITAL
CLAMP METER NCVD - 6 FUNCTION
MODEL NO: TM105
Thank you for purchasing a Sealey product. Manufactured to a high standard, this product will, if used according to these instructions,
and properly maintained, give you years of trouble free performance.
IMPORTANT: PLEASE READ THESE INSTRUCTIONS CAREFULLY. NOTE THE SAFE OPERATIONAL REQUIREMENTS, WARNINGS & CAUTIONS. USE
THE PRODUCT CORRECTLY AND WITH CARE FOR THE PURPOSE FOR WHICH IT IS INTENDED. FAILURE TO DO SO MAY CAUSE DAMAGE AND/OR
PERSONAL INJURY AND WILL INVALIDATE THE WARRANTY. KEEP THESE INSTRUCTIONS SAFE FOR FUTURE USE.
1. SAFETY
1.1. PERSONAL PRECAUTIONS
9When using this multimeter, please observe all normal safety rules concerning:
9Protection against the dangers of electrical current.
9Protection of the meter against misuse.
9Full compliance with safety standards can only be guaranteed if used with the test leads supplied. If necessary, they must be replaced with
genuine Sealey leads with the same electrical ratings. Failure to do so will invalidate the warranty.
8DO NOT use leads if damaged or if the wires are bared in any way.
1.2. GENERAL SAFETY INSTRUCTIONS
9Familiarise yourself with the application and limitations of the multimeter as well as the potential hazards.
9IF IN ANY DOUBT CONSULT A QUALIFIED ELECTRICIAN.
▲USE EXTREME CAUTION when working with high voltages.
9When the meter is connected to a circuit, DO NOT touch unused meter terminals.
9When the magnitude of the value to be measured is unknown, set the range selector to the highest value available.
9Before commencing testing, follow instructions below and select the correct input sockets, function and range on the multimeter.
9Before rotating the rotary switch to change functions, disconnect the test leads from the circuit under test.
9Take care when working with voltages above 35V DC or 25V AC rms. These voltages are considered a shock hazard. Keep fingers behind
the probe barriers whilst measuring.
8DO NOT test voltages above 600V - the circuitry of the multimeter may be destroyed.
WARNING! NEVER connect the multimeter to a voltage source / live circuit when the rotary switch is set to any other function apart from
Voltage testing.
WARNING! NEVER perform resistance, transistor, diode or continuity measurements on live circuits.
9ALWAYS discharge lter capacitors in power supplies and disconnect the power when making resistance or diode tests.
WARNING! Voltage checks on electrical outlets can be di󰀩cult 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”.
8DO NOT use the multimeter in a potentially explosive atmosphere.
9NEVER operate the meter unless the back cover and the battery and fuse doors are in place and fastened securely.
9If any abnormal readings are observed, the multimeter must be checked out by an authorised technician.
9When not in use, store the multimeter carefully in a safe, dry, childproof location out of direct sunlight.
9Storage temperature range -20°C to 60°C.
9ALWAYS turn o󰀨 the power and disconnect the test leads before opening the doors to replace the fuse or batteries.
9The user shall ensure that test probes are correctly selected in order to prevent danger. Probes shall be selected to ensure that adequate
barriers guard against inadvertent hand contact with live conductors under test and that probes have minimal exposed probe tips. Where
there is a risk of the probe tip short circuiting with other live conductors under test, it is recommended that the exposed tip length shall not
exceed 4mm.
WARNING! NEVER apply voltage or current to the meter that exceeds the specified maximum as shown below:
Input Limits
Function Maximum Input
Amps AC 400A
Volts DC, Volts AC 600V DC / AC
Resistance, Diode, Continuity 250V DC / AC
▲WARNING! USE EXTREME CAUTION when working with high voltages.
NOTE: The warnings, cautions and instructions referred to in this manual cannot cover all possible conditions and situations that may
occur. It must be understood that common sense and caution are factors which cannot be built into this product, but must be applied
by the operator.

NOTICE: 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.
4.1.  ACCURRENTMEASUREMENTS(g.4)
WARNING! Ensure that the test leads are disconnected from the meter before making current clamp measurements.
4.1.1. Set the Function switch to the 400.0A ~ 2.000A range.
4.1.2. If the range of the measured is not known, select the higher range rst then move to the lower range if necessary.
4.1.3. Press the trigger to open jaw. Fully enclose one conductor to be measured. The clamp meter LCD will display the reading.
4.2. DC / AC VOLTAGE MEASUREMENT
4.2.1. Insert the black test lead into the negative COM terminal and the red test lead
into the positive V terminal.
4.2.2. Set the function switch to the V position.
4.2.3. Select AC or DC with the MODE button.
4.2.4. Connect the test leads in parallel to the circuit under test.
4.2.5. Read the voltage measurement on the LCD display.
4.3. RESISTANCE MEASUREMENT
4.3.1. Insert the black test lead into the negative COM terminal and the red test lead
into the positive terminal.
4.3.2. Set the function switch to the Ω •))) position.
4.3.3. 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.
4.3.4. For Resistance tests, read the resistance on the LCD display.
4.4. DIODE AND CONTINUITY MEASUREMENTS (g.5)
4.4.1. Insert the black test lead banana plug into the negative COM jack and the red test lead banana plug into the positive diode
jack.
4.4.2. Turn the rotary switch to the Ω •))) position.
4.4.3. Press the MODE button until “ “ appears in the display.
4.4.4. 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.

4.4.5. For Continuity Tests if resistance is <150Ω a tone will sound.
4.5. 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
4.5.1. Touch the probe tip (g.2item14) to the live conductor or insert into the live side of the electrical outlet.
4.5.2. 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 sensor. This is normal
operation.

4.7.  DATAHOLDBUTTON(g.2item5)
To freeze the LCD meter reading, press the data hold button. The data hold button is located on the left side of the meter (top button).
While data hold is active, the HOLD display icon appears on the LCD. Press the data hold button again to return to normal operation.
4.8.  MAXHOLDBUTTON(g.2item10)
The Max. Hold position is used to measure the maximum value. The maximum measured value is updated continuously. Pressing once
again, the button will release the hold and allow a further measurement.
4.9.  RANGEBUTTON(g.2item9)
When the meter is rst turned on, it automatically goes into Auto Ranging. This automatically selects the best range for the
measurements being made and is generally the best mode for most measurements. For measurement situations requiring that a range
be manually selected, perform the following:
4.9.1. Press the RANGE button. The “Auto Range” display indicator will turn o󰀨, The “Manual Range” display indicator will turn on.
4.9.2. Press the RANGE button to step through the available ranges until you select the range you want.
4.9.3. Press and hold the RANGE button for 2 seconds to exit the Manual Ranging mode and return to Auto Ranging.
