8. technician turns the multimeter on by its switch and then selects the appropriate dial or switch positions to configure the multimeter to read the desired electrical parameter such as DC voltage The technician energizes the circuit being measured then holding the two probes one in each hand the technician carefully touches the pointed ends of the two probes to the part of the circuit being measured to make electrical contact being careful not to touch the probes to anything else or to each other The multimeter will then display the magnitude and polarity of the parameter on its display as long as the probes are making contact with the circuit under test For example to measure the voltage of the backup battery in a desktop Mac which is typically located somewhere on the main logic board 1 Locate the battery on the logic board and identify its type so you know what its expected voltage capacity should be Most recent desktop Mac backup batteries should be 3 6 DC Volt capacity 2 Identify the battery s positive and negative terminals they are usually marked as and on the logic board somewhere near the battery 3 Turn on and configure the multimeter for DC voltage Ensure the multimeter s display reads 0 0 DC Volts when not measuring anything 4 Carefully touch the black negative multimeter probe to the negative battery terminal and the red positive multimeter probe to the positive battery terminal being caref

12. ch cables and connectors rather than simply touching the multimeter probe tips to the circuit There is also a special third probe jack on most multimeters that 1s used only for current measurements Readings are in units of Amps Amperes or milliamps thousandths of an Amp Caution Extreme care should be taken when making current measurements as it is very easy to short the circuit out and damage it by incorrectly connecting the probes Safety Tips when Using a Multimeter Here is a summary of some important safety tips when using a multimeter to measure electrical circuits Please consult the operator s guide for the multimeter being used for specific instructions and tips Be sure the test leads and multimeter switch es are in the correct position for the desired measurement Never use the multimeter if the meter or the test leads look damaged Never measure resistance in a circuit when power is applied Never touch the probes to a voltage source when a test lead is plugged into the 10 A or 300 mA current input jack e To avoid damage or injury never use the multimeter on circuits that exceed the maximum ratings specified for that meter e Never apply more than the rated voltage between any input jack and earth ground e Be careful when working with voltages above 60 V DC or 30 V AC Such voltages pose a shock hazard e Keep your fingers behind the finger guards on the test probes when making measurements e To avoid false readings

19. ved by disconnection This is because a multimeter measuring resistance actually sources a small amount of constant electrical current coming out of its probes which flows through the probes into the cable or circuit being measured and this allows the multimeter to measure this electrical flow and calculate the resistance from the voltage drop measured between its two probes Attempting to measure resistance in an energized circuit will not only cause inaccurate readings it can also be dangerous and may damage either the circuit under test the multimeter or both Resistance measurements are therefore usually only made on things like disconnected cables and connectors to verify a good or bad electrical connection Verifying Circuit Current Flow Amps DC You can also use a multimeter on DC current settings to measure the amount of electrical current flowing through a circuit such as when verifying the charging circuitry in an Apple portable product by measuring the amount of DC current flowing through a connected AC power adapter This is rarely done during most troubleshooting scenarios because it involves connecting the multimeter in series with the circuit being tested which is an invasive procedure In series means that the multimeter is actively connected into the circuit such that the circuit s current also flows directly through the meter and this usually requires breaking into the circuit being tested using special pat
