5. Torolàlana miasa

The AN101 features automatic ranging for most measurements, simplifying operation. Always ensure the test leads are correctly connected and the function dial is set to the desired measurement type.

5.1 Fampandehanana ankapobeny

1. Turn the rotary switch to the desired function.
2. Ampifandraiso amin'ny faritra na ny singa andramana ireo taribin'ny fitsapana.
3. Vakio ny sandan'ny refy eo amin'ny efijery LCD.
4. Ampiasao ny MIFIDY button to toggle between AC/DC modes where applicable (e.g., Voltage, Ankehitriny).
5. Ampiasao ny Range button to switch between auto-ranging and manual ranging.
6. Ampiasao ny MANOHANA tsindrio ny bokotra hampijanonana ny famakiana ankehitriny eo amin'ny efijery. Tsindrio indray mba hamoahana azy.

5.2 Fandrefesana DC Voltage (V–)

1. Apetraho ny switch rotary V–.
2. Connect the red test lead to the positive (+) side of the DC voltage source and the black test lead to the negative (-) side.
3. Vakio ny voltage value on the display. The meter will automatically select the appropriate range.

5.3 Fandrefesana AC Voltage (V∼)

1. Apetraho ny switch rotary V∼.
2. Ampifandraiso amin'ny alalan'ny "AC voltage" ireo "test tariby"tage loharano.
3. Vakio ny voltage value on the display. The meter will automatically select the appropriate range.

5.4 Measuring DC Current (µA–, mA–)

1. ZAVA-DEHIBE: Ensure the circuit is de-energized before connecting the meter in series.
2. Apetraho ny switch rotary µA– or mA– depending on the expected current.
3. Break the circuit and connect the multimeter in series with the load. The red lead connects to the higher potential side, and the black lead to the lower potential side.
4. Ampiharo hery amin'ny circuit.
5. Vakio ny sanda ankehitriny eo amin'ny efijery.

5.5 Measuring AC Current (µA∼, mA∼)
