This is part 4 mobile maintenance Practical tutorial. In this practice video we will know about Multi-Meter and how to use it! Read the operations bellow!
ይህ ክፍል 4 የሞባይል ጥገና ትምህርት ነው፡፡ በዚህ የተግባር ትምህርት ስለ ሜልትሜትር እቃና አጠቃቀሙንም ጭምር የምንማማር ይሆናል፡፡
ማስጠንቀቂያ፦ማንኛውንም ነገር በምትለኩበት ጊዜ ያልተፈቀደ ከመጥን በላይ የሆነን DC Ampere, DC Volt, AC Current ወይም AC Volt ለመለካት መሞከር በአካላችንና በእቃችን ላይ ጉዳት ሊያደርስ ስለሚችል መጥንቀቅ አስፈላጊ ነው፡፡
Measurement Operations
A.AC or DC Voltage Testing
*The DC voltage ranges are: 200mV, 2V, 20V, 200V and 1000V.
*The AC voltage ranges are: 2 V, 20V, 200V and 750V
*To measure DC or AC voltage, connect the Meter as follows:
1. Insert the red test lead into the V terminal and the black test lead into the COM terminal.
2. Set the rotary switch to an appropriate measurement position in V or V~
3. Connect the test leads across with the object being measured. The measured value shows on the display.
B.DC Current Testing
*The measurement ranges of DC current are: 200mA and 10A. To measure current, do the following:
1. Turn off power to the circuit. Discharge all high- voltage capacitors.
2. Insert the red test lead into the mA or 10A terminal and the black test lead into the COM terminal.
3. Set the rotary switch to an appropriate measurement position in Ampere.
4. Break the current path to be tested. Connect the red test lead to the more positive side of the break and the black test lead to the more negative side of the break.
5. Turn on power to the circuit. The measured value shows on the display.
C.Resistance Testing
*The resistance ranges are: 200Ω, 2kΩ, 20kΩ, 200kΩ, 2MΩand 20MΩ.
To measure resistance, connect the Meter as follows:
1. Insert the red test lead into the Ω terminal and the black test lead into the COM terminal.
2. Set the rotary switch to an appropriate measurement position in Ω range.
3. Connect the test leads across with the object being measured. The measured value shows on the display.
D. Diode Testing
*Use the diode test to check diodes, transistors, and other semiconductor devices.
*The diode test sends a current through the semiconductor junction, and then measures the voltage drop across the junction.
*A good silicon junction drops between 0.5V and 0.8V.
To test a diode out of a circuit, connect the Meter as follows:
1. Insert the red test lead into the VΩ terminal and the black test lead into the COM terminal.
2. Set the rotary switch to the Diode Symbol.
3. For forward voltage drop readings on any semiconductor component, place the red test lead on the component’s anode and place the black test lead on the component’s cathode. The measured value shows on the display.
E.Continuity
To test for continuity, connect the Meter as below:
1. Insert the red test lead into the VΩ terminal and the black test lead into the COM terminal.
2. Set the rotary switch to Diode Symbol.
3. Connect the test leads across with the object being measured.
*The buzzer does not sound when the resistance value is greaterthan50 . The circuit is disconnected. The buzzer sounds continuously when the resistance value is less than or equal30Ω. The circuit is in good condition.
