4. Enstalasyon

4.1 Enstalasyon batri

The DT33D multimeter requires one 9V (6F22) battery (not included) for operation.

1. Jwenn kouvèti konpatiman batri a sou dèyè miltimèt la.
2. Carefully slide or unscrew the cover to open the compartment.
3. Insert a new 9V battery, ensuring correct polarity (+ and -).
4. Ranplase kouvèti lòj batri a epi an sekirite li.

4.2 Konekte fil tès yo

The multimeter comes with a pair of test leads (red and black).

• Mete fil tès nwa a nan priz antre 'COM' (komen) an.
• Pou pifò mezi (voltage, resistance, continuity, and low current), insert the red test lead into the 'VΩmA' input jack.
• For high current measurements (up to 10A), insert the red test lead into the '10A MAX' input jack.

5. Operasyon Enstriksyon

To operate the multimeter, select the desired function using the rotary switch and connect the test leads to the circuit or component being measured.

5.1 DC VoltagMezi e (V–)

Used for measuring direct current voltage in circuits.

1. Mete switch rotary la sou volim DC ou vle a.tage (V–) range (e.g., 200mV, 2V, 20V, 200V, 500V).
2. Connect the red test lead to the positive (+) side of the circuit and the black test lead to the negative (-) side.
3. Li voltage valè sou ekspozisyon an.

5.2 AC VoltagMezi e (V∼)

Used for measuring alternating current voltage.

1. Mete switch rotary la sou volim AC ou vle a.tage (V∼) range (e.g., 200V, 500V).
2. Konekte fil tès yo atravè vòltaj AC a.tage sous.
3. Li voltage valè sou ekspozisyon an.

5.3 Mezi Kouran DC (A–)

Used for measuring direct current flowing through a circuit.

1. Enpòtan: Dekonekte kouran an nan sikwi a anvan ou konekte miltimèt la an seri.
2. Set the rotary switch to the desired DC Current (A–) range (e.g., 2000uA, 20mA, 200mA, 10A).
3. Insert the red test lead into the appropriate current input jack ('VΩmA' for low current, '10A MAX' for high current).
4. Connect the multimeter in series with the circuit, ensuring the current flows through the meter.
5. Mete kouran nan sikwi a epi li valè aktyèl la sou ekran an.

5.4 Mezi Rezistans (Ω)

Used for measuring the resistance of components.

1. Enpòtan: Ensure the component is isolated from power and discharged before measuring resistance.
2. Set the rotary switch to the desired Resistance (Ω) range (e.g., 200Ω, 2kΩ, 20kΩ, 200kΩ, 2MΩ, 20MΩ).
3. Konekte fil tès yo atravè konpozan an.
4. Li valè rezistans nan ekspozisyon an.

5.5 Tès kontinwite

Used to check for an open or closed circuit.

1. Enpòtan: Asire w sikwi a pa gen enèji anvan ou fè yon tès kontinwite.
2. Set the rotary switch to the continuity (♪) position.
3. Touch the test leads together; the meter should beep and display a low resistance value.
4. Connect the test leads across the circuit or component you wish to test.
5. If the circuit is continuous (closed), the meter will beep and display a low resistance. If it is open, no beep will sound, and the display will show 'OL' (Over Limit).

6. Antretyen

6.1 Netwayaj

To maintain the accuracy and longevity of your multimeter, keep it clean.

• Siye ka a ak anonsamp twal ak yon savon dou. Pa sèvi ak pwodui abrazif oswa solvang.
• Ensure no moisture enters the meter's casing.

6.2 Ranplasman batri

When the low battery indicator appears on the display, replace the 9V battery as described in Section 4.1. Failure to do so may result in inaccurate readings.

NAN. Depanaj

If your multimeter is not functioning as expected, consider the following common issues:

• Pa gen ekspozisyon oswa ekspozisyon fèb: Tcheke batri a. Ranplase li si sa nesesè.
• Lekti ki pa kòrèk: Ensure the correct function and range are selected. Verify test lead connections. Check battery level.
• 'OL' (Over Limit) Display: The measured value exceeds the selected range. Switch to a higher range or ensure the circuit is closed for continuity tests.
• Pa gen bip kontinuite: Ensure the circuit is de-energized. Check if the component is truly open.
