1. Entwodiksyon
The MustOOL MT336 is a versatile 2-in-1 True RMS Digital Clamp Meter and Oscilloscope. This device allows for non-contact measurement of AC current waveforms, DC/AC voltage, resistance, capacitance, frequency, and temperature. It features a waveform display for quick analysis and includes functions like diode testing and continuity checks. Designed for safety and efficiency, it is an essential tool for electrical measurements.

2. Enfòmasyon sou Sekirite
Always adhere to safety precautions when using electrical testing equipment. Failure to do so may result in electric shock, injury, or damage to the meter or equipment under test.
- Pa depase limit maksimòm opinyon yo pou okenn fonksyon.
- Ensure the test leads are in good condition and properly connected before use.
- Do not use the meter if it appears damaged or if the battery cover is not properly closed.
- Pran anpil prekosyon lè w ap travay ak voltages pi wo pase 60V DC oswa 30V AC RMS.
- Always disconnect power to the circuit before making resistance, capacitance, or diode measurements.
- Remove test leads from the meter before opening the battery compartment.

4.1 Enstalasyon batri
- Ensure the meter is powered off and no test leads are connected.
- Jwenn konpatiman pil la sou dèyè mèt la.
- Devise kouvèti lòj batri a.
- Insert three AAA 1.5V batteries, observing correct polarity.
- Ranplase kouvèti lòj batri a epi an sekirite li ak vis la.
4.2 Konekte fil tès yo
Pou voltage, resistance, capacitance, frequency, diode, and continuity measurements:
- Mete plon tès nwa a nan COM Jack antre (komen).
- Mete plon wouj tès la nan VΩHz jack antre.
For temperature measurements, connect the temperature probe to the designated input ports.
5. Operasyon Enstriksyon
5.1 Power On/Off
Press the power button to turn the meter on. The meter will automatically shut down after 15 minutes of inactivity to conserve battery life. Press the power button again to turn it off manually.
5.2 Mezi Kouran AC (Clamp Fonksyon)
- Select the AC current mode (usually indicated by 'A~' or a similar symbol).
- Peze deklanche a pou louvri clamp machwè.
- Enclose a single conductor (not a power cord with multiple wires) within the clamp machwè.
- Release the trigger to close the jaw securely around the conductor.
- Read the AC current value and waveform on the display.

5.4 Resistance, Capacitance, Frequency, Diode, and Continuity
For these functions, ensure the circuit is de-energized before connecting the test leads. Select the desired function using the mode buttons and follow standard measurement procedures for multimeters.
- Rezistans (Ω): Measures the electrical resistance of a component.
- Kapasite (F): Measures the capacitance of capacitors.
- Frekans (Hz): Mezire frekans yon siyal AC.
- Tès dyòd: Checks the forward voltaggout e nan yon dyòd.
- Tès kontinwite: Indicates if a circuit is complete with a low resistance path (typically with an audible beep).
5.5 Mezi Tanperati
Connect the temperature probe to the meter's designated input. Select the temperature function and place the probe tip on the object or area to be measured. The temperature will be displayed in Celsius or Fahrenheit.
6. Antretyen
6.1 Netwayaj
Wipe the meter with a dry, soft cloth. Do not use abrasives or solvents. Keep the input terminals free of dirt and moisture.
6.2 Ranplasman batri
When the low battery indicator appears on the display, replace the batteries as described in Section 4.1. Use three new AAA 1.5V batteries.
6.3 Depo
If the meter is not used for an extended period, remove the batteries to prevent leakage and damage. Store the meter in a cool, dry place away from direct sunlight.
NAN. Depanaj
| Pwoblèm | Kòz posib | Solisyon |
|---|---|---|
| Kontè a pa limen. | Pil ki mouri oswa ki mal enstale. | Ranplase pil yo, asire w ke polarite a kòrèk. |
| Pa gen lekti oswa "OL" ki parèt. | Open circuit, out of range, or incorrect function selected. | Check connections, select appropriate range/function, or ensure circuit is closed. |
| Lekti ki pa kòrèk. | Low battery, dirty test leads/terminals, or external interference. | Replace batteries, clean leads/terminals, move away from strong electromagnetic fields. |
