To measure Active Power and Phase Angle using the MAJOR TECH MT790 ថាមពលបីដំណាក់កាល Clamp ម៉ែត្រសូមអនុវត្តតាមជំហានទាំងនេះ ដូចដែលបានរៀបរាប់នៅក្នុងសៀវភៅណែនាំ៖
1. **Select Active Power + Phase Angle Range:**
- Dial the Rotary to KW to select Active power + Phase angle range.
- Press the lever to open the transformer jaw, and clamp them to the corresponding phase of the tested conductor.
2. **Connecting Method:**
- Insert red, blue, yellow test leads to L1, L2, L3 input terminal and connect them to every live wire of the 3 phase.
- Insert black test leads to the COM input terminal and connect it to the neutral wire of the 3 phase.
3. **Measuring Instructions:**
- Press SEL to choose the first phase (Ø1). The display shows the active power kW value and the PG value of the first phase.
- Press Σ if you need to get the sum of watts.
- Repeat the process for the second phase (Ø2) and third phase (Ø3) by selecting them using SEL.
- Press Σ and hold for 1 second to display the 3-phase sum of active power value and apparent power value.
- Press ▲ to step through different measurements like three-phase sum of active power, reactive power, power factor, and apparent power.
- Press Σ and hold for 1 second again to return to the normal measuring mode.
4. **ចំណាំបន្ថែម៖**
- Ensure not to measure higher than AC voltage 750V and AC current 1000A to avoid damage or harm.
- Follow the correct connecting methods for 3-phase 4 wires or 3-phase 3 wires configurations as shown in the manual.
- Pay attention to the display symbols and measurement ranges to ensure accurate readings.
By following these steps and guidelines from the manual, you can effectively measure Active Power and Phase Angle using the MAJOR TECH MT790 ថាមពលបីដំណាក់កាល Clamp ម៉ែត្រ.
