Multimeter (Multimeter). Multimeter measurement tool that is considered necessary for electronic work, because as a basic measure used by electrical currents and voltage is the electrical resistance, whether test or make repairs to various circuit, it is necessary to measure the total of those values. Multimeter Voltmeter Ammeter Ohmmeter and combine them in a single movement (Movement) and use a single call "VOM" (Volt-Ohm-Milliammeter).The hierarchy using a DC voltmeter 1. connect the DC volts measurement voltage, while in parallel with the load exits. 2. set the meter's running neighborhood located in DCV. 3. set the switch to the correct measurement district. If you do not know the voltage to be measured, set the maximum measurement position (1, 000V) reduction and lower district, one at a time until the meter needle will point neighborhood values that are valid and easy to read. 4. in the position measured with DC voltmeter, but not while tap gauge positive or positive measure, while pulling out. The meter needle will always point wagging slightly, showing that it is measuring voltage (ACV). 5. measurement of direct voltage in the circuit will need to plug the correct measurement by measuring lead negative (-COM) black negative supply handles. Measuring lead polarity positive (+) Red meter to measure the voltage. Sequence the steps to use a ohm meter. 1. set the meter's running neighborhood neighborhood ohm. 2. use the red measuring cable plug into the positive connector. (+) And the black measuring line into the connector polarity negative (-COM). 3. adjust the measurement switch selectors, the seal correctly. 4. before bringing the measure to the meter in ohms, and every district will have to adjust the 0 is always ohm. 5. If the meter to the ohm meter will lead the resistance in the circuit, be sure the power switch is turned off (OFF) all the time. Caution in using multimeter. 1. do not expose the thermometer has been strong, such as sticks, falling from heights, defective Instrumentation. Damaged. 2. place the thermometer in position should the azimuth (horizontal) and run-time users. 3. before measuring, make sure every 12th w. Select the measurement always accurate district. 4. set the maximum scale of the Temple district while unknown points of course. 5. do not use the measurement of direct voltage ohm meter or a voltage switch. 6. when measuring DC voltage measuring terminals must be used, is always +- 7. when selecting the measurement end of the cable should not be measured in ohms, tap each other for too long. 8. users should switch off and unplug the measure option OFF go to the district. 9. should not Overload occurs (scale) multimeter. Often when making measurements must determine the location of an appropriate metric measurement. With the circuit to be measured. 10. do not use the multimeter for a long time before you can use the Function and Range switch should be rotated to reduce stiffness and, Good electrical contact 11. store the multimeter should be placed in the machine, always wrap (Case).
