Turn on the multimeter by pressing the power switch. Using the selector switch on the front of the multimeter, select the measurement function that is required. There is a choice of AC voltage, DC voltage, resistance and continuity. Press the range button to select an adequate measurement rang...
Tip:to measure voltage you have to connect your multimeter in parallel with the component you want to measure the voltage. Placing the multimeter in parallel is placing each probe along the leads of the component you want to measure the voltage. Example: measuring a battery’s voltage In this...
Next, connect the calculated value of resistors as discussed in the previous section to any one of the free ends of each series, you can connect the resistor at the positive end of the string or the negative end, the position doesn't matter because the resistor just needs to be in line ...
How to Read an Ohm Meter The ohm meter is one of the most basic pieces of electronic test equipment. It is often a range of settings on a multimeter (volt-ohm-milliammeter or VOM) as the ohm meter is a variation on the ampmeter, which measures small electrical current. There are two...
or the secondary winding voltage is increased to break the insulation, and a high voltage electric shock occurs. danger. Therefore, when changing the meter, such as changing the ammeter, the active meter, the reactive meter, etc., the current loop should be shorted before the meter is exchang...
The ohm meter is one of the most basic pieces of electronic test equipment. It is often a range of settings on a multimeter (volt-ohm-milliammeter or VOM) as the ohm meter is a variation on the ampmeter, which measures small electrical current. There are two main types of ohm meter:...
There are two places in this circuit that you shouldnotconnect the ammeter. First, don't connect the ammeter directly across the two battery terminals. This effectively shorts out the battery. It will get real hot, real fast. Second, don't connect one lead of the ammeter to the positive ...
Measure IIN– Connect an ammeter between the power source and the input to the buck (SYS test point). Measure VOUT– Connect a voltmeter across the output capacitor of phase x for output voltage (across kelvin sense test points OUTxS and PGNDxS, where x = 1...
aObtain three 30cm lengths of nichrome wire.Connect an ammeter,one piece of nichrome wire,a battery,and a switch in series,as shown.Record the reading on the ammeter 得到镍铬合金导线的三30cm长度。连接一个镍铬合金导线安倍计、一件,一个电池和一个开关在系列,如所示。记录读书在安倍计[translate] ...
Unlike direct current, alternating current (AC) does not find many applications in low-voltage electronics. It is the reason many multimeters do not feature an AC ammeter. But for those that do, measuring AC is a similar process as DC; the rotary dial needs to be set to AC, though. ...
