5. Коопсуздук маалыматы

Always adhere to safety precautions when using the multimeter to prevent electric shock or personal injury. This device is rated CAT III 1000V and CAT IV 600V. Ensure test leads are in good condition and properly connected. Do not attempt to measure voltages or currents exceeding the specified maximum limits. Always turn off power to the circuit before connecting or disconnecting test leads for resistance, capacitance, or diode tests. Use the NCV function as an initial check for live wires, but always verify with direct contact measurement when possible. Replace fuses with specified types and ratings only.

6. Иштөө нускамалары

The UNI-T UT161B features a rotary dial for function selection and several buttons for additional settings and features. Refer to the detailed illustrations below for component identification.

6.1. Негизги өлчөөлөр

1. Тtage (AC/DC): Rotate the dial to V~ (AC Voltagд) же V- (ТК көлөмүtage). Connect the test leads to the circuit in parallel. The display will show the voltage окуу.
2. Current (AC/DC): Rotate the dial to A~ (AC Current) or A- (DC Current). Ensure the circuit is de-energized. Connect the test leads in series with the circuit. Re-energize the circuit and read the current. For small currents, use mA or μA ranges.
3. Каршылык (Ω): Rotate the dial to Ω. Connect the test leads across the component to be measured. Ensure the component is isolated from the circuit.
4. Сыйымдуулук (F): Rotate the dial to F. Connect the test leads across the capacitor. Ensure the capacitor is discharged before measurement.
5. Frequency (Hz)/Duty Cycle (%): These functions are often integrated with voltage or current measurements. Select the appropriate range and press the Hz/% button to toggle between frequency and duty cycle.
6. Диод сыноо: Rotate the dial to the diode symbol. Connect the red lead to the anode and the black lead to the cathode. A forward voltage тамчы көрсөтүлөт. Ачык чынжырды текшерүү үчүн өткөргүчтөрдү тескери буруңуз.
7. Үзгүлтүксүздүк тести: Rotate the dial to the continuity symbol. Touch the test leads to the points to be tested. A buzzer will sound if continuity exists (low resistance).

6.2. NCV (контактсыз томtagд) Функция

NCV функциясы AC көлөмүн аныктоого мүмкүндүк беретtage without direct contact. Rotate the dial to NCV. Bring the top of the multimeter near the conductor. The device will provide audible beeps and a flashing light indication when AC voltage is detected, with the frequency of beeps and flashes increasing with stronger signals.

6.3. USB байланышы

The UT161B supports USB communication for data logging and analysis on a computer. Connect the provided USB cable to the multimeter's USB interface (located on the back, often under the kickstand) and to your computer. Install the necessary PC software (typically provided on a CD or available for download from the UNI-T webсайтына). view and record measurement data.

7. Техникалык тейлөө

7.1. Тазалоо

Ишти жарнама менен сүртүңүзamp кездеме жана жумшак жуугуч. Абразивдерди же эриткичтерди колдонбоңуз. Колдонуудан мурун аппарат толугу менен кургак экенин текшериңиз.

7.2. Батареяны алмаштыруу

When the battery indicator appears on the display, replace the batteries. Turn off the multimeter and disconnect all test leads. Open the battery compartment cover on the back of the device, replace the old batteries with new ones of the specified type, and securely close the cover.

7.3. Сактагычты алмаштыруу

The UT161B+ utilizes double ceramic (explosion-proof) fuse tubes for protection. If a fuse blows, turn off the multimeter and disconnect all test leads. Open the casing (refer to the full manual for specific instructions) and replace the blown fuse with a new one of the exact same type and rating to maintain safety and performance.
