- Khawm: AC/DC, ZERO, H/MAX (Data Hold/Max Hold).
- Cov tswv yim Terminals: COM (common) and VΩ (voltage/resistance) for test leads.
- Tes Guard: Provides protection against accidental contact.
4. Teeb tsa
4.1 Kev teeb tsa roj teeb
The PeakTech P 3131 requires two 1.5V AAA batteries (included). To install or replace batteries:
- Xyuas kom lub cuab yeej raug kaw.
- Nrhiav lub hau ntawm lub roj teeb rau sab nraum qab ntawm lub 'meter'.
- Siv lub hau ntswj los qhib lub thawv.
- Insert the two AAA batteries, observing correct polarity (+ and -).
- Hloov lub roj teeb lub hau npog thiab tuav nws nrog cov ntsia hlau.
When the low battery indicator appears on the display, replace the batteries immediately to ensure accurate measurements.
4.2 Kev Sib Txuas Cov Thawj Coj
Rau voltage, resistance, and continuity measurements, connect the supplied test leads:
- Ntxig qhov kev xeem dub coj mus rau hauv lub COM (common) input terminal.
- Ntxig lub liab xeem lead rau hauv lub VΩ input lub davhlau ya nyob twg.

5. Cov lus qhia ua haujlwm
5.1 Fais fab / Off
Rotate the function selector dial from the "OFF" position to any desired measurement function to power on the meter. To power off, rotate the dial back to "OFF". The meter features an automatic power-off function (can be deactivated) to conserve battery life.
5.2 Kev Ntsuas Tam Sim No AC/DC (Cl)amp)
To measure current without breaking the circuit:
- Tig lub function selector dial rau lub A~ (AC Current) or A= (DC Current) position.
- Nias lub AC / DC button if you need to switch between AC and DC current modes (if the dial position combines them).
- Nias lub ZERO button to zero the display before measuring DC current, especially for small currents, to compensate for residual magnetism.
- Qhib clamp puab tsaig los ntawm nias lub khawm.
- Enclose only ib conductor with the clamp puab tsaig. Xyuas kom lub puab tsaig kaw tag nrho.
- Nyeem tus nqi tam sim no ntawm LCD zaub.

5.3 AC / DC Voltage Kev ntsuas
Kev ntsuas voltage:
- Txuas cov kev xeem coj raws li tau piav qhia hauv Tshooj 4.2.
- Tig lub function selector dial rau lub V~ (AC Voltage) lub V= (DC Voltage) txoj haujlwm.
- Connect the test probes in parallel to the circuit or component you wish to measure.
- Nyeem voltage tus nqi ntawm LCD zaub.
5.4 Kev Ntsuas Kev Tiv Thaiv thiab Kev Txuas Ntxiv Mus
To measure resistance or check for continuity:
- Txuas cov kev xeem coj raws li tau piav qhia hauv Tshooj 4.2.
- Tig lub function selector dial rau lub Ω/))) (Resistance/Continuity) position.
- For resistance: Connect the test probes across the component. Ensure the circuit is de-energized.
- For continuity: Touch the test probes to the two points you want to check. A continuous beep indicates a low-resistance path (continuity).
- Nyeem cov nqi tiv thaiv ntawm LCD zaub.
5.5 Kev Ua Haujlwm Tshwj Xeeb
- True RMS: The meter measures True Root Mean Square values for AC voltage and current, providing accurate readings for non-sinusoidal waveforms.
- Kev Tuav Ntaub Ntawv (H): Nias lub H/MAX nias lub pob ib pliag kom khov qhov nyeem tam sim no ntawm qhov screen. Nias dua kom tso.
- Maximum Value Hold (MAX): Nias thiab tuav lub H/MAX button to capture and display the maximum measured value. Press again to exit.
- ZERO Function: Used to zero the display for DC current measurements to eliminate offset errors.
- Auto Raning: The meter automatically selects the appropriate measurement range.
- Auto Fais Fab: The meter automatically turns off after a period of inactivity to save battery. This feature can typically be disabled by holding a specific button during power-on (refer to the device's on-screen indicators or a more detailed manual if available).
