የተወሰኑ የመለኪያ ተግባራት፡
1. AC ጥራዝtagሠ መለኪያ
የተግባር መደወያውን ወደ ኤሲ ቮል ያዙሩትtage range (V~). Insert the probes into the socket to measure the AC voltage value. The common household current can be measured. For example, a reading of 238V for a common household socket.
2. ዲሲ ጥራዝtagሠ መለኪያ
የተግባር መደወያውን ወደ ዲሲ ቮልት ያዙሩትtage range (V-). Connect the probes across the component or power source. For example, measuring a 9V battery might show 1.06V if discharged or 8.99V if charged, proving the multimeter's high accuracy.
3. የዲሲ ወቅታዊ መለኪያ
To measure DC current, the multimeter must be connected in series with the circuit. Connect the probe in series at both ends of the dot line to measure DC current. For example, measuring the current of a fan connected to a battery.
IMPORTANT WARNING for AC Current Measurement: Do NOT directly contact the multimeter probes with AC current sources like measuring voltage. Direct contact will burn out the instrument! Always connect the multimeter IN SERIES with the circuit when measuring current.
4. የመቋቋም ልኬት
Adjust the multimeter to the resistance range (Ω). Connect the test leads across the component to measure its resistance value.
5. Diode መለኪያ
Switch the function dial to the diode gear. Accurately distinguish between positive and negative poles to measure the value. The multimeter will display the forward voltagሠ የ diode ጠብታ.
6. Triode (hFE) Measurement
Set the function range switch to the hFE position. Insert the transistor leads into the appropriate slots in the triode socket, ensuring it is of PNP or NPN type. The multimeter will display the transistor's current gain (hFE).
7. የሚሰማ ቀጣይነት ሙከራ
Turn the function dial to the continuity test position (indicated by a speaker icon). Connect the test leads across the circuit or component. If the circuit is connected (low resistance), the multimeter will emit a beep sound, and the detection indicator light will illuminate. No sound indicates an open circuit or high resistance.
