2. Set the rotary switch to the desired AC V range (e.g., 10V, 50V, 250V, 1000V). Start with the highest range if the voltage teu kanyahoan.
3. Connect the test probes in parallel across the component or circuit to be measured.
4. Baca voltage value from the appropriate AC V scale on the analog display.

6.3 DC Current Measurement (DC A)

1. For currents up to 250mA, connect the red lead to 'VΩmA+' and the black lead to 'COM'. For currents up to 10A, connect the red lead to '+10A' and the black lead to 'COM'.
2. Set the rotary switch to the desired DC A range (e.g., 0.05mA, 0.25mA, 2.5mA, 25mA, 250mA, 10A). Start with the highest range if the current is unknown.
3. penting: Connect the multimeter in series with the circuit to be measured. Break the circuit and insert the meter.
4. Read the current value from the appropriate DC A scale.

6.4 AC Current Measurement (AC A)

1. For currents up to 250mA, connect the red lead to 'VΩmA+' and the black lead to 'COM'. For currents up to 10A, connect the red lead to '+10A' and the black lead to 'COM'.
2. Set the rotary switch to the desired AC A range (e.g., 0.05mA, 0.25mA, 2.5mA, 25mA, 250mA, 10A). Start with the highest range if the current is unknown.
3. penting: Connect the multimeter in series with the circuit to be measured. Break the circuit and insert the meter.
4. Read the current value from the appropriate AC A scale.

6.5 Ukur Résistansi (Ω)

1. Connect the red lead to 'VΩmA+' and the black lead to 'COM'.
2. Set the rotary switch to the desired Resistance range (e.g., X1, X10, X1K, X10K, X100K).
3. Nol adjustment: Short the test leads together. While shorted, adjust the 'Ω ADJ' knob until the needle points to '0' on the Ohm scale. This must be done for each resistance range.
4. Connect the test probes across the component to be measured (ensure the component is de-energized).
5. Read the resistance value from the Ohm scale and multiply by the selected range multiplier.

6.6 Uji Batré (BATT)

1. Connect the red lead to 'VΩmA+' and the black lead to 'COM'.
2. Set the rotary switch to the 'BATT' function (1.5V or 9V).
3. Connect the test probes to the battery terminals, observing polarity.
4. Baca vol batrétage from the appropriate battery scale.

6.7 Diode and Transistor Check

1. Set the rotary switch to the 'Ω X 10' range for transistor and diode checks.
2. For transistor hFE measurement, insert the transistor leads into the appropriate NPN or PNP sockets.
3. For diode check, use the extra jack as indicated in the specifications.

6.8 Continuity Cék

1. Set the rotary switch to the 'Continuity Check' position (often indicated by a speaker icon).

9. Cara ngungkulan

• Teu maca atawa maca teu stabil: Check battery levels and replace if necessary. Ensure test leads are securely connected and not damaged. Verify the rotary switch is set to the correct function and range.
• Incorrect resistance reading: Perform Ohm adjustment (zeroing) as described in Section 6.5. Ensure the component being tested is de-energized.
• Pangukuran arus teu jalan: Check the fuse(s) and replace if blown (refer to Section 8.3). Ensure the meter is connected in series with the circuit.
• Needle not moving: Ensure the meter is powered on (if applicable for specific functions) and the test leads are making good contact.

10. Tips pamaké

• Salawasna mimitian ku rentang pangluhurna: Nalika ngukur hiji vol kanyahoantage or current, always start with the highest range setting and then decrease it until you get a suitable reading. This prevents overloading the meter.
• Zero Ohm adjustment: Remember to perform the Ohm adjustment (zeroing) every time you change the resistance range for accurate readings.
• Observe polarity: For DC measurements, observing polarity is important. If the needle deflects backward, reverse the test leads.
• Analog vs. Digital: Analog multimeters are great for observing trends and fluctuating signals, as the needle movement can show changes more dynamically than a digital display.
