After battery installation, turn the rotary switch to any function to power on the device. The OLED display will illuminate, and a self-test will be performed. If the display does not light up, check battery installation.
5. Parentah Operasi
5.1 Pangukuran Dasar
To perform basic measurements, select the desired function using the rotary switch and connect the test leads to the appropriate input terminals.
- Voltage Measurement (V~, V-): Connect the red lead to the VΩHz terminal and the black lead to the COM terminal. Select AC (V~) or DC (V-) voltage.
- Current Measurement (A, mA, µA): Connect the red lead to the appropriate current terminal (10A, 440mA, or µA) and the black lead to the COM terminal. Select the desired current range. Ensure the circuit is de-energized before connecting the multimeter in series.
- Pangukuran Résistansi (Ω): Connect the red lead to the VΩHz terminal and the black lead to the COM terminal. Select the Ω function.
- Continuity Test (audible beep and visual alert): Connect the red lead to the VΩHz terminal and the black lead to the COM terminal. Select the continuity function. The meter will beep and visually alert for continuity.
5.2 Fitur canggih
- LPF (Low Pass Filter): Activates a low pass filter to remove high-frequency noise and harmonics, useful for measurements on variable frequency drives (VFDs).
- Qik-V: Allows for quick determination of AC or DC voltage without manually selecting the mode.
- Data logging: The U1272A can store up to 10,000 readings. Refer to the detailed user manual for instructions on setting up logging intervals and transferring data to a PC.
