Multimeter (Multimeter). Multimeter is treated as a necessary instrument for electronic measuring instruments used shall be the base value is the voltage, electrical power and electrical resistance, either as a test or inspection, maintenance and repair of the circuit, it is necessary to measure them. Multimeter Voltmeter Ammeter Ohmmeter and include them in the same and use the same movement (Movement), so called "VOM" (Volt-Ohm-Milliammeter).The stage using DC volt meter. 1. connect the DC volts while measuring voltage across the load. 2. set the meter's district located in DCV. 3. adjust the timer to measure the correct district. If you do not know the voltage to be measured, set the measuring position Max (1, 000V), then downgrade to a lower district, one at a time until the meter needle will point the district values that are readable and correct. 4. where the meter is not measuring DC volts, but as tap gauge anode to anode or pull out measuring. The meter needle will always wag a little show that point is a switch voltage (ACV). 5. measure the voltage in the circuit to be measured must be plugged in to the correct measurement line polarity negative (-COM) black negative polarity of the power handle. Measuring lead anode (+) Red meter to measure the voltage by various points. Procedure using the ohm meter. 1. set the meter's neighborhood district ohms 2. using the measuring cables plug into the Red connector positive. (+) And the black measuring cable plug into the connector polarity negative (-COM). 3. adjust the timer to a small neighborhood Temple CD. 4. before applying ohm meter to measure every time and in every district, they must always be 0 ohms. 5. If the ohm meter to measure will be up in-circuit resistance, be sure to turn off the power switch on (OFF) all the time.
