How to use a multimeter

Multimeters are of two sorts – Analog Multimeter and Digital Multimeter. The most effective method to utilize Multimeter to check voltage, Ohms, battery, progression and so forth is pretty much the equivalent. The main contrast is that an advanced Multimeter has a computerized show of the considerable number of readings. A simple Multimeter has a needle-type pointer that moves to a perusing while at the same time testing any gadget or electronic part.

Most Multimeters, frequently spelt as Multi Meter, will have the following:

Function and Range Switch:

This change is utilized to choose the capacity and wanted range and in addition to turn the instrument. With the end goal to expand the life of the battery of the Multimeter, this switch must be kept in the "OFF" position when the instrument isn't being used.

Display or LCD: 

To show every one of the readings.

Common Jack:

Plug in connector for dark (negative) test lead or test.

V? mA Jack: 

Plug in connector for red (positive) test lead or test for all voltage, opposition and current (with the exception of 10A) estimations.

10A Jack:

 Plug in connector for red (positive) test lead or test for 10A estimation.

Packing List or Items that come with a New Multimeter:

1. Multimeter.
2. Set or red and dark test leads or tests.
3. Battery.
4. Thermoelectric couple.
5. Operator Instruction Manual.

How to Use a Multimeter (Analog and Digital): Instruction:

How to Measure DC (Direct Current) Voltage/DC Voltage Measurement:

1. Connect the red test lead to "V"? Black jacks "and black lead to "COM" jack.
2. Set the "Range Switch" in the desired DC-V position. If the voltage is not known for measuring, then set the switch to the highest limit and reduce it to satisfactory reading.
3. Connect a test device or circuit is being measured.
4. Turn on the power of the measuring device, device or component. With voltage polar polarity, the voltage on the digital multimeter digital display will be visible.

How to measure the AC (optional current) voltage using a multimeter / AC voltage measurement:

1. Connect the red test lead to "V"? MA jack "and black lead to "COM" jack
2. Set the "Range Switch" in the desired AC V position.
3. Connect test devices, electronic components or circuits are being measured.
4. The voltage value will display multimeter on digital or analog.

How To Measure DC (Optional ) At Present Using A Multimeter / DC Current Measurement:

1. Connect the red check to "V"? MA Jack "and" COM "Jack's Black Check To measure the DC flow between 200 MA and 10 A, connect the red probe to" 10 A "jack completely blues.
2. Set the "Range Switch" in the desired AC position.
3. To measure the circuit open and connect the probe with the chain in the load in which the current is to be measured.
4. Read the value on the display.

How to measure resistance by using a multimeter/resistance measurement:

1. Connect the red probe to "V"? "mA Jack" and black probe to"COM" jack
2. Set the "Range switch" in the desired Ohms (?) Position.
3. If the measuring resistor is connected to the circuit then turn off the power before the measurement and discharge all the capacitors.
4. Connect the probe to the circuit being measured.
5. Read the resistance value on the display.

How to measure diode/diode measurement:

1. Connect the red test lead to "V"? mA jack and black lead to "COM" jack 
2. Set the "Range switch" in the diode position.
3. Red Test connects the diode and the black test lead leads to the cathode.
4. Further voltage drop in MV will be displayed in the screen or display. If the diode is reversed, then "1" image will be displayed.

How to measure the transistor HFE / diode measurement:

1. Set the "Range switch" in HFEposition.
2. Determine whether the transistor is NPN or PNP type and locate emitter, base and collector leads. Insert the lead in the appropriate hole of the HFE Socket on the front panel of the multimeter.
3. The multimeter will display the estimated HFE value of current 10 μm and VCD 2.8 V.

How to measure Continuity /audio buzzer stability:

1. Connect the red test lead to "V"? Black lead of MA Jack "and" CO "Jack
2. Set the "Range Switch" in the Buzzer.
3. The connect test leads to two points for the test. If the resistance is less than 100 ohms then the buzzer will sound, which means that continuity is fine.

Test Signal Use:

1. Set the "Range switch" on the signal symbol.
2. What does a test signal appear between "V?? MA Jack" and "COM" jack? The output voltage is approximately 5 VP-P with 50-ohm impedance.

How to measure temperature/temperature measurement:

1. Connect the K-type thermoelectric pair to "V"? MA Jack "and" COM "Jack.
2. Set "Range switch" to "Temperature status".
3. The display will read temperature values in Celsius or Fahrenheit.

How to measure room temperature/room temperature measurement:

Most multimeters can easily measure the room temperature from 0 to 35 degrees Celsius. Just set the "Range Switch" in the RT position and the current room temperature will be displayed.

Warning:

To avoid electric shock, danger or damage, measure voltage over 1000V or 750V above the earth. Different multimeters can have different measurement limits. Please read the instruction manual carefully before running multimeter.

Before using a multimeter, inspect the inspection of cracks, breaks or nuts for test leads, connectors, and probes.

Before trying to open the matter of multimeter, be sure to disconnect the test lead or check from any energetic electronic circuit to avoid the electrical shock.

How to take care of your multimeter

When you are using a multimeter, then it is your proper care and to prevent it from any harm:

1. Changing the fuse: Multimeter fuse rarely requires shock or replacement. If this happens, then this operator is caused by error or error. If necessary, replace the old pole with a new polarity with appropriate polarity.
2. Battery replacement: If a battery symbol appears on the display, it indicates that the battery is to be replaced.
