4. Setha
4.1 Ukufakwa kwebhethri
The U1272A is powered by batteries. To install or replace batteries:
- Ensure the multimeter is turned OFF and disconnect all test leads from the terminals.
- Thola ikhava yekhompathi yebhethri ngemuva kweyunithi (bheka uMdwebo 3.3).
- Unscrew the retaining screws and carefully remove the cover.
- Insert new batteries, observing correct polarity (+/-) as indicated inside the compartment.
- Shintsha isembozo bese usivikela ngezikulufo.
4.2 Amandla Okuqala Avuliwe
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. Iziqondiso Zokusebenza
5.1 Izilinganiso Eziyisisekelo
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.
- 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 Izici Ezithuthukile
- I-LPF (Isihlungi Se-Low Pass): 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.
- Ukungena Kwedatha: 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. Isondlo
6.1 Ukuhlanza
Ukuze uhlanze i-multimeter, sula ikesi ngesikhangisoamp 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 Ukulinganisa
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 Isitoreji
Uma ingasetshenziswa isikhathi eside, susa amabhethri ukuze uvimbele ukuvuza. Gcina i-multimeter endaweni epholile, eyomile, kude nokukhanya kwelanga okuqondile kanye namazinga okushisa aphezulu.
7. Ukuxazulula izinkinga
| Inkinga | Imbangela Engenzeka | Isixazululo |
|---|---|---|
| Asikho isibonisi noma isibonisi esifiphele | Amabhethri aphansi noma aphelelwe yisikhathi; Ukufakwa kwebhethri okungalungile | Shintsha amabhethri; Hlola i-polarity yebhethri |
| Ukufundwa okungalungile | Incorrect function selected; Damaged test leads; Out of calibration | Verify function setting; Inspect/replace leads; Contact service for calibration |
| Meter does not respond | Frozen display; Internal error | Turn off and on again; Remove and reinsert batteries; If problem persists, contact support |
For issues not listed here, or if solutions do not resolve the problem, contact Keysight customer support.
