4. Fametrahana

4.1 Fametrahana bateria

1. Ataovy azo antoka fa maty ny multimeter.
2. Tadiavo ny toerana misy ny bateria ao ambadiky ny metatra.
3. Ampiasao ny tournevis mba hamahana ny visy izay mihazona ny fonon'ny bateria.
4. Esory ny fonon'ny batterie.
5. Insert the specified batteries (e.g., 4 x AAA batteries) observing the correct polarity (+/-).
6. Soloy ny fonon'ny batterie ary henjana tsara ny visy.

4.2 Test Lead Connection

Always connect the test leads to the appropriate input jacks for the measurement you intend to perform. Incorrect connection can lead to damage to the meter or personal injury.

• For most measurements (Voltage, Resistance, Continuity, Diode, Capacitance, Frequency), connect the black test lead to the fr jack sy ny taribin'ny fitsapana mena mankany amin'ny VΩHz jack.
• For current measurements (mA/µA), connect the black test lead to the fr jack sy ny taribin'ny fitsapana mena mankany amin'ny mAµA jack.
• For high current measurements (up to 10A), connect the black test lead to the fr jack sy ny taribin'ny fitsapana mena mankany amin'ny 10A MAX FUSED jack.

5. Torolàlana miasa

This section outlines the basic steps for performing common measurements with your U1242C DMM.

5.1 Fandrefesana AC/DC Voltage

1. Avereno amin'ny voltage range (V~ for AC, V- for DC). The meter may have an auto-ranging feature.
2. Ampifandraiso amin'ny tariby fitsapana mainty ny fr jack sy ny taribin'ny fitsapana mena mankany amin'ny VΩHz jack.
3. Connect the test probes in parallel across the circuit or component to be measured.
4. Vakio ny voltage sanda eo amin'ny efijery.

5.2 Fandrefesana ny herin'aratra AC/DC

CAUTION: Never connect the meter in parallel with a voltagloharano rehefa mandrefy ny herinaratra. Mety handrava ny fuse na hanimba ny metatra izany.

1. Turn the rotary switch to the desired current range (A~ for AC, A- for DC, or mA/µA ranges).
2. Ampifandraiso amin'ny tariby fitsapana mainty ny fr jack.
3. For mA/µA measurements, connect the red test lead to the mAµA jack. For 10A measurements, connect the red test lead to the 10A MAX FUSED jack.
4. Open the circuit where current is to be measured and connect the meter in series with the circuit.
5. Vakio ny sanda ankehitriny eo amin'ny efijery.

5.3 Fandrefesana ny fanoherana

1. Avadiho ho amin'ny elanelana Ω (Ohms) ny switch rotary.
2. Ampifandraiso amin'ny tariby fitsapana mainty ny fr jack sy ny taribin'ny fitsapana mena mankany amin'ny VΩHz jack.
3. Hamarino tsara fa tsy misy herinaratra intsony ny faritra na ny singa alohan'ny handrefesana ny fanoherana.
4. Ampifandraiso amin'ilay singa horefesina ireo fitaovana fitsapana.
5. Vakio ny sandan'ny fanoherana eo amin'ny fampisehoana.

5.4 Fitsapana mitohy

1. Turn the rotary switch to the continuity symbol (speaker icon).
2. Ampifandraiso amin'ny tariby fitsapana mainty ny fr jack sy ny taribin'ny fitsapana mena mankany amin'ny VΩHz jack.
3. Ataovy azo antoka fa tsy misy herinaratra ao amin'ny faritra.
4. Ampifandraiso manerana ny faritra na ny singa ireo probe fitsapana.
5. The meter will beep if continuity is detected (resistance below a certain threshold).

5.5 Logging data

The U1242C supports data logging. Refer to the detailed user manual for specific instructions on activating and managing data logging functions, including connecting to a PC with the software bundle for extended logging capabilities.
