5. Fametrahana

5.1. Fametrahana bateria

The Fluke 77-4 is powered by a 9V battery. To install or replace the battery:

1. Ataovy azo antoka fa maty ny multimeter.
2. Tadiavo ny fonon'ny fitoeran'ny bateria eo amin'ny faran'ny multimeter.
3. Ampiasao ny tournevis mba hamahana ny visy mihazona ny fonony.
4. Remove the cover and insert a new 9V battery, observing correct polarity.
5. Replace the cover and tighten the screw(s).

5.2. Fampifandraisana ireo Tariby Fitsapana

Always connect the black test lead to the COM jack. Connect the red test lead to the appropriate input jack for your measurement:

• VΩHz: Ho an'ny voltage, resistance, continuity, diode, and frequency measurements.
• mA: Ho an'ny fandrefesana ny courant hatramin'ny 400mA.
• 10A: Ho an'ny fandrefesana ny courant hatramin'ny 10A.

6. Torolàlana miasa

Before taking any measurement, ensure the test leads are correctly connected and the function dial is set to the appropriate position.

6.1. Fandrefesana ny Volan'ny AC/DCtage

1. Turn the rotary dial to V~ (AC Voltage) or V (DC Voltagary).
2. Ampifandraiso amin'ny jack COM ny tariby fitsapana mainty ary amin'ny jack VΩHz ny tariby fitsapana mena.
3. Tsindrio amin'ny teboka misy ny vol ny probe fitsapanatage no refesina.
4. Vakio ny voltage sanda eo amin'ny efijery.

6.2. Measuring Resistance (Ohms)

1. Hamarino tsara fa tsy misy herinaratra ao amin'ny faritra elektrika alohan'ny handrefesana ny fanoherana.
2. Turn the rotary dial to Ω.
3. Ampifandraiso amin'ny jack COM ny tariby fitsapana mainty ary amin'ny jack VΩHz ny tariby fitsapana mena.
4. Touch the test probes across the component or circuit segment.
5. Vakio ny sandan'ny fanoherana eo amin'ny fampisehoana.

6.3. Measuring Current (Amperes)

Tandremo: Current measurements require breaking the circuit and inserting the multimeter in series. Incorrect connection can blow the fuse or damage the meter.

1. De-energize ny circuit.
2. Determine the expected current range. For currents up to 400mA, turn the dial to mA and connect the red lead to the mA jack. For currents up to 10A, turn the dial to A and connect the red lead to the 10A jack.
3. Ampifandraiso amin'ny jack COM ny fitarihana fitsapana mainty.
4. Tapaho ny fizaran-tany ary ampifandraiso mifanesy amin'ny entana ny probe fitsapana.
5. Re-energize the circuit and read the current value.
6. De-energize the circuit before disconnecting the multimeter.

6.4. Using HOLD, MINMAX, and RANGE Functions

• HATAO: Tsindrio ny bokotra HAZONY mba hampijanonana ny famakiana ankehitriny eo amin'ny efijery. Tsindrio indray mba hamoahana azy.
• MINMAX: Press the MINMAX button to activate recording. The meter will display the maximum, minimum, and average readings sequentially. Press again to cycle through Min, Max, Avg. Hold the button to exit.
• RANGE: In auto-ranging modes, the meter automatically selects the best range. Press RANGE to switch to manual ranging. Each subsequent press will cycle through available ranges. Hold the button to return to auto-ranging.
