4.2 Ngecas Batré

Connect the provided charging cable to the multimeter and a suitable power adapter. The multimeter cannot be used while charging.

4.3 PC and Bluetooth Connectivity

The UT181A supports both USB and Bluetooth communication for data transfer and remote monitoring. The USB interface allows synchronization with a Windows operating system for data logging and analysis. An optional Bluetooth adapter (UT-D07A) can be used for wireless connectivity to increase measurement safety by allowing remote operation.

5. Parentah Operasi

5.1 Daya Hurung/Pareuman

Press and hold the power button (usually marked with a circle and a vertical line) for approximately 3 seconds to turn the multimeter on or off. The display will show a boot-up sequence.

5.2 Pamilihan Fungsi

Rotate the central rotary dial to select the desired measurement function. Use the blue "SELECT" button to toggle between different modes within a single rotary switch position (e.g., AC/DC voltage, résistansi/kontinuitas).

5.3 Fungsi Pangukuran

• Voltage (AC/DC/Low-Z): Pilih vol anu cocogtage range (V~ for AC, V- for DC, Lo-Z V~ for low impedance AC).
• Ayeuna (AC/DC): Select A~ or A- for current measurements. Ensure test leads are connected to the correct current input jacks (10A, mA, or µA).
• Résistansi (Ω): Measures electrical resistance.
• Kapasitansi (F): Measures capacitance. The UT181A has a maximum capacitance range of 60mF.
• Uji kontinuitas: Used to check for open or closed circuits (audible beep for continuity).
• Tés Diode: Mariksa fungsi dioda.
• Frékuénsi (Hz) / Siklus Tugas (%): Measures the frequency and duty cycle of AC signals.
• Suhu (°C/°F): Use the provided temperature adapter and thermocouples for temperature measurements.
• Non-Kontak Voltage (NCV): Ngadeteksi AC voltage tanpa kontak langsung.

5.4 Data Logging and Analysis

The UT181A can log up to 20,000 data points. Connect the multimeter to a PC via USB or Bluetooth (with optional adapter) to transfer and analyze logged data using the provided software. The software allows for trend capture and data comparison.
