KAIWEETS Digital Multimeter HT118A User Manual

Introducere

The KAIWEETS HT118A Digital Multimeter is a versatile electrical testing instrument designed for accurately measuring various electrical parameters. It features True RMS (TRMS) for precise readings of non-sinusoidal waveforms and offers a 6000-count display for high resolution. This multimeter is capable of measuring AC/DC voltage, AC/DC current, resistance, capacitance, frequency, duty-cycle, temperature, and includes functions for diode testing, continuity checking, non-contact voltage (NCV) detection, and Live wire detection. Its auto-ranging capability simplifies operation, making it suitable for both professional and automotive applications.

Înființat

Instalarea bateriei

The KAIWEETS HT118A Multimeter requires two AA batteries for operation. The batteries are included with the product.

1. Localizați compartimentul bateriei pe spatele multimetrului.
2. Folosiți o șurubelniță mică pentru a deschide capacul compartimentului bateriei.
3. Introduceți cele două baterii AA, asigurându-vă că polaritatea este corectă (+ și -).
4. Puneți la loc capacul compartimentului bateriei și fixați-l cu șurubul.

Conectarea cablurilor de testare

Always ensure the test leads are properly connected to the multimeter before taking measurements. The multimeter features LED lightning jacks that will illuminate to indicate the correct ports for your selected function.

1. Conectați cablul de testare negru la COM Mufă de intrare (comună).
2. Connect the red test lead to the appropriate input jack based on the measurement you intend to perform. The LED lights will guide you. For most voltage, resistance, continuity, diode, capacitance, and frequency measurements, use the VΩHz jack. For current measurements, use the 10A or mA/µA jack.

Instrucțiuni de operare

The KAIWEETS HT118A features auto-ranging, simplifying most measurements. Rotate the central dial to select the desired measurement function.

Măsurarea Voltage (AC/DC)

1. Turn the rotary switch to the "V~" (AC Voltage) sau „V-” (Volum DCtage) poziţia.
2. Connect the test leads to the circuit or component to be measured in parallel.
3. The multimeter will automatically select the appropriate range and display the voltagcitirea.

Measuring Current (AC/DC)

1. Turn the rotary switch to the "A~" (AC Current) or "A-" (DC Current) position.
2. Connect the multimeter in series with the circuit. Ensure the red test lead is in the 10A or mA/µA jack as appropriate.
3. Valoarea curentă va fi afișată.

Măsurarea rezistenței

1. Turn the rotary switch to the "Ω" (Resistance) position.
2. Connect the test leads across the component whose resistance you wish to measure. Ensure the component is de-energized.
3. The resistance reading will be displayed.

Măsurarea capacității

1. Turn the rotary switch to the "Capacitance" position.
2. Connect the test leads across the capacitor. Ensure the capacitor is discharged before testing.
3. The capacitance reading will be displayed.

Măsurarea temperaturii

1. Turn the rotary switch to the "°C/°F" (Temperature) position.
2. Connect the included thermocouple to the appropriate input jacks (usually marked with temperature symbols).
3. Place the tip of the thermocouple on or in the object whose temperature you want to measure.
4. The temperature reading will be displayed in Celsius or Fahrenheit.

Test de continuitate

1. Turn the rotary switch to the "Continuity" position (often shared with diode test).
2. Conectați sondele de testare la circuit sau la componentă.
3. A continuous beep indicates a complete circuit (continuity).

Testul diodei

1. Turn the rotary switch to the "Diode" position (often shared with continuity test).
2. Conectați sonda roșie la anod și sonda neagră la catodul diodei.
3. Volumul înaintetage drop will be displayed. Reverse the leads; an open circuit reading indicates a good diode.

Vol. Fără contacttagDetectarea e (NCV) și a cablurilor sub tensiune

Funcția NCV permite detectarea volumului de curent alternativtage without direct contact. The Live function helps identify live wires.

1. Turn the rotary switch to the "NCV Live" position.
2. For NCV, bring the top of the multimeter close to the wire or outlet. An audible alarm and LED indicator will signal the presence of AC voltage.
3. For Live wire detection, insert the red test lead into the "Live" input jack (if available, or use the NCV function as described).

Funcții suplimentare

• ȚINEȚI: Apăsați butonul HOLD pentru a îngheța valoarea curentă de pe afișaj. Apăsați din nou pentru a o elibera.
• MAX / MIN: Press the MAX/MIN button to record the maximum or minimum reading during a measurement session.
• Iluminare de fundal: Apăsați butonul de iluminare de fundal (adesea indicat de pictograma unui bec) pentru a activa sau dezactiva iluminarea de fundal a afișajului.
