3. Devise vis (yo) ki kenbe yo epi retire kouvèti batri a.
4. Connect a new 9V battery to the battery clips, observing correct polarity.
5. Mete pil la nan konpatiman an epi remete kouvèti a, byen sere l ak vis(yo).

Nòt: Replace the battery immediately when the low battery indicator appears on the display to maintain measurement accuracy.

2. Konekte fil tès yo

Toujou konekte fil tès nwa a nan COM priz (komen). Konekte fil tès wouj la nan priz antre ki apwopriye a selon kalite mezi a:

• Pou voltage, resistance, capacitance, diode, continuity, and temperature measurements, connect the red lead to the VΩmA Jack.
• For current measurements up to 200mA, connect the red lead to the VΩmA Jack.
• Pou mezi kouran jiska 20A, konekte fil wouj la ak 20A Jack.

Atansyon: Incorrect lead connection can damage the meter or the circuit under test.

Enstriksyon Operasyon

Follow these steps for various measurement functions.

1. Power On/Off

Peze a POUVWA button to turn the multimeter on. The meter features an auto power-off function to conserve battery life. To turn it off manually, press the POUVWA bouton ankò.

2. Mezire Volim DCtage (V-)

1. Konekte plon nwa a COM and the red lead to VΩmA.
2. Set the rotary switch to the desired V- range (e.g., 2V, 20V, 200V, 1000V). If the voltage se enkoni, kòmanse ak entèval ki pi wo a epi diminye jan sa nesesè.
3. Connect the test leads in parallel across the component or circuit to be measured.
4. Li voltage valè sou ekspozisyon LCD a.

3. Mezire AC Voltage (V~)

1. Konekte plon nwa a COM and the red lead to VΩmA.
2. Set the rotary switch to the desired V~ range (e.g., 2V, 20V, 200V, 750V).
3. Connect the test leads in parallel across the AC source or component.
4. Li AC voltage valè sou ekspozisyon LCD a.

4. Measuring DC Current (A-)

1. Atansyon: Always connect the meter in series with the circuit. Never connect it in parallel across a voltage source when measuring current.
2. Dekonekte pouvwa nan kous la.
3. Break the circuit at the point where current is to be measured.
4. For currents up to 200mA, connect the black lead to COM and the red lead to VΩmA.

Antretyen

Bon antretyen asire lonjevite ak presizyon miltimèt ou a.

• Netwayaj: Siye ka a ak anonsamp twal ak detèjan twò grav. Pa sèvi ak abrazif oswa solvang.
• Ranplasman batri: Replace the 9V battery when the low battery indicator appears. Refer to the "Battery Installation" section for instructions.
• Ranplasman Fuse: If the current measurement function fails, the fuse may need replacement. This typically requires opening the back case. Refer to the safety warnings on the back of the meter (Figure 3) and consult a qualified technician if unsure. Use only fuses of the specified type and rating.
• Depo: If the meter is not used for an extended period, remove the battery to prevent leakage. Store the meter in a cool, dry place, away from direct sunlight and extreme temperatures.
