• For high DC current measurements (up to 10A), insert the red test lead ao amin'ny 10ADC fampidirana jack.

5. Torolàlana miasa

To operate the multimeter, select the desired function and range using the rotary switch.

5.1. Fandrefesana ny Volan'ny DCtage (DCV)

1. Insert the red lead into the VΩmA jack and the black lead into the COM jack.
2. Set the rotary switch to the desired DCV range (e.g., 200m, 2000m, 20, 200, 1000). Start with the highest range if the voltage tsy fantatra.
3. Ampifandraiso amin'ilay singa na faritra horefesina ireo tariby fitsapana.
4. Vakio ny voltage sanda eo amin'ny efijery LCD.

5.2. Fandrefesana AC Voltage (ACV)

1. Insert the red lead into the VΩmA jack and the black lead into the COM jack.
2. Set the rotary switch to the desired ACV range (e.g., 200, 750). Start with the highest range if the voltage tsy fantatra.
3. Ampifandraiso amin'ilay singa na faritra horefesina ireo tariby fitsapana.
4. Vakio ny voltage sanda eo amin'ny efijery LCD.

5.3. Measuring DC Current (DCA)

1. For currents up to 200mA: Insert the red lead into the VΩmA jack and the black lead into the COM jack.

4. For transistor hFE measurement, insert the transistor leads (Emitter, Base, Collector) into the appropriate sockets (E, B, C) in the hFE test socket, ensuring correct NPN or PNP type selection.
5. Read the hFE value on the LCD display.

6. Fikojakojana

6.1. Fanadiovana

Fafao ny metatra casing sy adamp lamba sy savony malefaka. Aza mampiasa akora manimba na ranoka solvent. Ataovy azo antoka fa maina tanteraka ny metatra alohan'ny hampiasana azy.

6.2. Fanoloana bateria

Refer to Section 4.1 for battery installation instructions. Replace the 9V battery when the low battery indicator appears on the display to maintain measurement accuracy.

7. Famahana olana

• Tsy misy fampisehoana: Jereo ny fametrahana ny batterie ary ataovy azo antoka fa ampy ny fiampangana ny batterie.
• 'OL' or '1' on Display: This usually indicates an over-range condition or an open circuit. Select a higher range or check connections.
• Famakiana diso: Ensure the correct function and range are selected. Check test lead connections and battery condition.
• No Continuity Tone: Verify the circuit is de-energized and the leads are making good contact.
