Power Measurement
Quick Start Manual
This chapter explains setting and measurement procedures using the follow-
ing example.
Be sure to read the “Operating Precautions” section of the instruction manual
as w
ell as other precautionary information that can be found its chapters
before using the instrument.
Procedures
See p.8 for more information about what you will need to perform measure-
ment.
* The reactive-power-meter method is used to measure reactive power directly from the
voltage and current, like a reactive power meter installed for large power consumers.
Power Measurement
• Data is automatically output to the PC card at 5-minute intervals.
• Average value (voltage, current, and power) and integrated power are
stored on the PC card.
• The reactive power-meter method* is not used.
Example:
Measure the power of a Three-phase 3-wire 200 V line for 7 days.
1. Connect the power cord. (p.10)
2. Connect the voltage cord to the 3169. (p.11)
3. Connect the clamp sensor to the 3169. (p.12)
4. Insert the PC card. (p.13)
5. Turn the Power switch ON. (p.14)
6. Basic settings (p.15)
7. Connect the voltage cords and clamp sensors to the line to be
measured. (p.18)
8. Confirm the range. (p.20)
9. Checking the wiring. (p.22)
10. Measurement settings (p.24)
11. Start measurement. (p.27)
