4.2 Анхдагч асаалттай
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. Ашиглалтын заавар
5.1 Үндсэн хэмжилтүүд
To perform basic measurements, select the desired function using the rotary switch and connect the test leads to the appropriate input terminals.
- Ботьtage Хэмжилт (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.
- Эсэргүүцлийн хэмжилт (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 Нарийвчилсан онцлог
- LPF (Бага нэвтрүүлэх шүүлтүүр): 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.
- Өгөгдлийн бүртгэл: 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.
6. Засвар үйлчилгээ
6.1 Цэвэрлэгээ
Мультиметрийг цэвэрлэхийн тулд хайрцгийг зараар арчинаamp cloth and a mild detergent. Do not use abrasives or solvents. Ensure the device is powered off and leads are disconnected before cleaning.
6.2 Шалгалт тохируулга
The U1272A is factory calibrated. For continued accuracy, periodic calibration by a qualified service center is recommended. Refer to Keysight's official support channels for calibration services.
6.3 Хадгалалт
Удаан хугацаагаар ашиглаагүй үед гоожихоос сэргийлж батерейг салгаж авна уу. Мультиметрийг сэрүүн, хуурай газар, нарны шууд тусгал болон хэт өндөр температураас хол хадгална уу.
