SEALEY MM102 Professional Auto Ranging Digital Multimeter SAFETY

PERSONAL PRECAUTIONS

• When using this meter, please observe all normal safety rules concerning:
• Protection against the dangers of electric current.
• Protection of the meter against misuse.
• Full compliance with safety standards can only be guaranteed if used with the test leads supplied. Failure to do so will invalidate the warranty.
• DO NOT use leads if damaged or if the wire is bared in any way.

GENERAL SAFETY INSTRUCTIONS

• Familiarise yourself with the applications, limitations and hazards of the meter. If in any doubt consult a qualified electrician.
• When the meter is linked to a measurement circuit, DO NOT touch unused meter terminals.
• When the scale of the value to be measured is unknown set the selector to the highest range available.
• Before rotating the range selector to change functions, disconnect test leads from the circuit under test.
• WARNING! Never perform resistance measurements on live circuits.
• Always be careful when working with multimeter. Keep your fingers behind the probe guards while measuring.
• When not in use, store the meter carefully in a safe, dry, childproof location. Storage temperature range -10°C to 50°C

The 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.

OPERATION

WARNING! Risk of electrocution. High voltage circuits, both AC and DC are dangerous and should be measured with great care. Always turn the function switch to the off position when the meter is not in use.
AC/DC VOLTAGE MEASUREMENTS

• DO NOT.measure.DC/AC.voltages.if.a.motor.on.the.circuit.is.being.switched.ON.or.OFF..Large.voltage.surges.may.occur.that.can damage the meter.
• Set the function switch to the green V position.
• Press the MODE button to indicate “DC” or “AC” on the display.
• 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.
• Read the voltage in the display.
• DC/AC CURRENT MEASUREMENTS
• Set.the.function.switch.to.the.µA/mA.position..
• For.current.measurements.up.to.2000uA.DC/AC,.set.the.function.switch.to.the.mA.position
• Press.the.MODE.button.to.indicate.“DC”./.“AC”.on.the.display.
• Remove power from the circuit under test, then open up the circuit at the point where you wish to measure current.
• 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.
• Apply power to the circuit.
• Read the current in the display.
• RESISTANCE MEASUREMENT
• WARNING! To avoid electric shock, disconnect power to the unit under test and discharge all capacitors before taking any resistance measurements. Remove the batteries and unplug the line cords.
• Set.the.function.switch.to.the.Ω. position.
• Press.the.MODE.button.to.indicate.Ω.on.the.display.
• Touch the test probe tips across the circuit or part under test. It is best to disconnect one side of the part under test so the rest of the circuit will not interfere with the resistance reading.
• Read the resistance in the display.

CONTINUITY CHECK

• WARNING! To avoid electric shock, never measure continuity on circuits or wires that have voltage on them.
• Set the function switch to the.Ω……….position.
• Press the MODE button to indicate on the display
• Touch the test probe tips to the circuit or wire you wish to check.
• If.the.resistance.is.less.than.approximately.150Ω,.the.audible.signal.will.sound..If.the.circuit.is.open,.the.display.will.indicate.“OL”. DIODE TEST
• Set the function switch.to.the.Ω position.
• Press the MODE button to indicate on the display.
• WARNING! Risk of Electrocution. Before use, always test the Voltage Detector on a known live circuit to verify proper operation Position.the.non.contact.probe.fig.1.1..in.close.proximity.to.the.cable/conductor.
• If AC voltage is present, the detector light will illuminate.

NOTE: The conductors in electrical cables are often twisted. For best results, move the non contact probe along a length of the cable to assure the probe is in close proximity to the live conductor.

NOTE: The detector is designed with high sensitivity. Static electricity or other sources of energy may randomly operate the sensor. This is normal operation.

HOLD BUTTON

• The Data Hold function allows the meter to “freeze” a measurement for later reference
• Press the “DATA HOLD” button to “freeze” the display, the “HOLD” indicator will appear.
• Press the “DATA HOLD” button to return to normal operation.

FLASHLIGHT

• Press and hold the top button to turn the flashlight on. Release the button to turn the flashlight off. AUTO POWER OFF
• The auto off feature will turn the meter off after 15 minutes.

MAINTENANCE
