Introduction to Digital Multimeter Measurment

1) Introduction of DIGITAL clock

Digital watches have a number of advantages over mechanical clock, which is higher accuracy, the impedance of the higher clock therefore causes no pressure drop when measured in weak electric current, measured frequency alternating dimensional, but this clock has several drawbacks is powered up or down electronic circuits, hard look results in faster test case, not measurable degree of convergence cycling.

2) - Measure the DC voltage (or AC)

Set the clock on the scale voltage DC or AC

• 
  
  Red needle clock in socket "VΩ mA" black rod into the hole labeled "COM"


• 
  
  Press the DC / AC to DC if selected scales are measured voltage dc or ac AC if measured.


• 
  
  Rotate switch position "V" let the highest scale if unknown voltage, if the value reported in decimal, we reduced the scale later.


• 
  
  Place the scale on a voltage to be measured and read the value on the LCD screen of the meter.


• 
  
  If set opposite probe (with DC) clock will report a negative value (-)

3) - Measuring DC current (AC)

• 
  
  Transfer clock que pour the ladder mA if small flow measurement, or 20A if large current measurement.


• 
  
  Rotate switch to position "A"


• 
  
  Press the DC / AC to DC current measurement selected or AC


• 
  
  Set serial probe with test circuit


• 
  
  Read the value displayed on the screen.

4) - Measuring resistor

• 
  
  Return position the plug as the voltage measurement.


• 
  
  Rotate switch for position measurement "Ω" if unknown resistor value is selected the highest scale, if the result is a decimal, we fell down.


• 
  
  Place the strips on both ends of the resistor.


• 
  
  Read the value on the screen.


• 
  
  Resistance measuring function can measure the communication circuit, assuming measured by the scale of the wire guide becomes, if the clock pulse is emitted forward calls

5) - Measure frequency

• 
  
  Rotate switch for position "FREQ" or "Hz"


• 
  
  To scale as when measuring voltage.


• 
  
  Place the probe on the point to be measured


• 
  
  Read the value on the screen.

6) - Measure Logic

• 
  
  Measure Logic is measured in number of vessels (Digital) or measure the foot on the processor, measured essentially Logic state electricity meter - Symbol "1" or without electricity "0", the following metrics:


• 
  
  Rotate switch for position "LOGIC"


• 
  
  Place the red rod in position to be measured in mass black rod


• 
  
  Monitor only "▲" is reported a logic high level, only "▼" are reported with a low logic

7) - Measurement of other functions

• 
  
  Digital multimeter number and some other functions like Measure measure diodes, capacitors Measure, Measure Transistor but if we measure the components above, we use mechanical watches up will result in better and faster measurement
