5. Uppsetning
5.1. Uppsetning rafhlöðu
- Gakktu úr skugga um að slökkt sé á tækinu.
- Finndu rafhlöðulokið aftan á tækinu.
- Use a screwdriver (if necessary) to open the cover.
- Insert two (2) AAA batteries, observing the correct polarity (+/-) as indicated inside the compartment.
- Settu hlífina yfir rafhlöðuhólfið aftur og festu það.
5.2. Fyrsta ræsing
After battery installation, turn the function dial from "OFF" to any measurement setting to power on the device. The display should illuminate, indicating readiness for use.
6. Notkunarleiðbeiningar
6.1. Kveikt/slökkt
- To power on, rotate the function dial from the "OFF" position to the desired measurement function.
- To power off, rotate the function dial back to the "OFF" position.
6.2. Mæling á riðstraumi (Clamp)
- Rotate the function dial to the "A" (Current) setting.
- Opnaðu clamp jaw by pressing the lever.
- Enclose only one conductor (live or neutral) within the clamp kjálki. Gakktu úr skugga um að kjálkinn sé alveg lokaður.
- Lestu núverandi gildi á LCD skjánum.
6.3. Binditage Mæling (V)
- Rotate the function dial to the "V" (Voltage) stilling.
- Connect the red test lead to the "V" input terminal and the black test lead to the "COM" input terminal.
- Connect the test leads in parallel across the circuit or component to be measured.
- Lestu binditage gildi á LCD skjánum.
6.4. Power Measurement (W, Wh, var, VA)
The CM3286 can measure various power parameters. Select the appropriate setting on the function dial (W for active power, Wh for energy, var for reactive power, VA for apparent power). Connect test leads for voltage og clamp the jaw around the current conductor as per the specific measurement method outlined in the full manual (not provided here, but implied by the device's capabilities).
6.5. Frequency Measurement (Hz)
Select the "Hz" setting on the function dial. Connect test leads across the circuit where frequency is to be measured, similar to voltage mæling.
6.6. Phase Sequence Detection
The device features a "Phase Detect" function. Refer to the detailed instructions in the complete manual for proper connection and interpretation of phase sequence on single-phase or three-phase circuits.
6.7. Using Buttons (HOLD, MAX/MIN, RANGE, SHIFT)
