Introduction
The 3169-20 and the 3169-21 Clamp On Power HiTester is supplied with a
instruction manual in addition to this manual. Please be sure to read both
manuals.
This manual provides a simplified description of the instrument (key names
and functions as well as screens) and measurement process, from the preparation stage to the completion of measurement, using an example application.
For current input with this instrument, a clamp-on sensor (optional) is
required. For
you are using.
Be sure to review the instruction manual carefully before using the instrument to ensure safe operation.
Model Numbers
In this manual, "3169" is used as the instrument model.

Quick Start Manual
• 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)

Power Measurement
Power Measurement
This chapter explains setting and measurement procedures using the following example.
Be sure to read the “Operating Precautions” section of the instruction manual
as well as other
before using the instrument.
Procedures
See p.8 for more information about what you will need to perform measurement.
precautionary information that can be found its chapters
* 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.
