The KM401 multimeter requires 3 AAA batteries for operation. If the batteries are not pre-installed, follow these steps:
To prepare the multimeter for measurements:
Rotate the central dial to select the desired measurement function. For functions with multiple modes (e.g., AC/DC Voltage, Diode/Continuity), press the FUNC жеткиликтүү режимдер аркылуу айлануу үчүн баскычты басыңыз.

Figure 2: The KM401 offers multiple measurement functions.
Айланма рычагды V~ (AC Voltagд) же V- (ТК көлөмүtage) position. Connect the test leads in parallel to the circuit or component to be measured. The display will show the voltage окуу.

Figure 3: Measuring AC/DC Voltage and Current with the KM401.
Set the rotary dial to the A~ (AC Current) or A- (DC Current) position, selecting either the mA or 10A input jack as appropriate. Connect the multimeter in series with the circuit to measure current. Ensure the circuit power is off before connecting.
Set the rotary dial to the Ω (Resistance) position. Connect the test leads across the component to measure its resistance. Ensure the component is de-energized before measurement.

Figure 4: Various measurement capabilities including Resistance, Capacitance, Diode, and Temperature.
Айлануучу дискти коюңуз Ω жайгаштырыңыз жана басыңыз FUNC to select continuity mode (indicated by a buzzer icon). Touch the test leads to the points to be tested. A continuous beep indicates continuity (low resistance).
Айлануучу дискти коюңуз Ω жайгаштырыңыз жана басыңыз FUNC to select diode mode (indicated by a diode symbol). Connect the red lead to the anode and the black lead to the cathode of the diode. The display shows the forward voltagд тамчы.
Айлануучу дискти коюңуз F (Capacitance) position. Connect the test leads across the capacitor. Ensure the capacitor is discharged before testing.
Айлануучу дискти коюңуз Hz (Frequency) position. Connect the test leads to the signal source. The display will show the frequency in Hertz.
Айлануучу дискти коюңуз NCV position. Move the top of the multimeter near a live wire or electrical outlet. The meter will beep and the NCV indicator will light up if AC voltage түз байланышсыз аныкталат.

Айлануучу дискти коюңуз Live position. Insert the red test lead into the live wire socket or touch it to the live wire. The display will indicate if the wire is live.
The KM401 can perform phase sequence detection. Set the rotary dial to the Фаза position. Follow the on-screen prompts to connect the test leads to the phases. The meter will indicate the phase sequence.

Айлануучу дискти коюңуз ° C / ° F position. Connect the thermocouple to the input jacks, observing polarity. Place the thermocouple tip on the object or in the environment whose temperature is to be measured.
басыңыз БЕРҮҮ Учурдагы көрсөткүчтү дисплейде тоңдуруу үчүн баскычын басыңыз. Кармоо функциясын бошотуу үчүн аны кайра басыңыз.
басыңыз ЖАРЫК button (often combined with the HOLD button) to turn on the display backlight for improved visibility in dim conditions. Some models also feature a built-in flashlight, activated by a separate button or a long press of the light button, to illuminate the work area.

Мультиметрди сүртүңүз casing жарнама мененamp кездеме жана жумшак жуугуч каражат. Абразивдүү тазалоочу каражаттарды же эриткичтерди колдонбоңуз. Колдонуудан мурун түзмөк толугу менен кургак экенин текшериңиз.
Узак мөөнөткө колдонулбаганда, батарейкалардын агып кетпеши үчүн алып салыңыз. Мультиметрди салкын, кургак жерде, тике күндүн нурунан жана экстремалдык температурадан алыс сактаңыз.
When the low battery indicator appears on the display, replace the batteries promptly to ensure accurate readings. Refer to Section 4.1 for battery installation instructions.
