5.1 මූලික මිනුම්

To perform basic measurements, select the desired function using the rotary switch and connect the test leads to the appropriate input terminals.

• වෙළුමtage 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.
• Resistance Measurement (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 උසස් විශේෂාංග

• LPF (අඩු පාස් පෙරහන): 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.
• දත්ත ලොග් කිරීම: 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.
