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 prepa-
ration stage to the completion of measurement, using an example application.
For current input with this instrument, a clamp-on sensor (optional) is
required. For details, refer to the instruction manual for the clamp-on sensor
you are using.
Be sure to review the instruction manual carefully before using the instru-
ment to ensure safe operation.
Model Numbers
In this manual, "3169" is used as the instrument model.
M
Notation
In this manual, the risk seriousness and the hazard levels are classified as
follows.

Operation Keys
Key Names and Functions
MEASURE key Switches to a screen that displays measurements.
SET UP key Switches to a screen that displays settings or the next screen.
FILE key Used to work on files.
I RANGE key Sets the current measurement range for the circuit to be mea-
sured on-screen.
U RANGE key Sets the voltage measurement range.
SAVE key Enables the manual saving of measurement data on the PC
card or in internal memory. Manual saving is not possible dur-
ing time-series measurement.
COPY key Outputs screen image data to the PC card, internal memory, or
a printer.
START/STOP key Starts or stops time-series measurements including integration
measurement.
START/STOP LED Flashes in green while the instrument is standing by for time-
series measurement, and lights in green while the instrument is
performing time-series measurement.

Goes on when the reactive-power-meter method is ON.
Instruction manual "5.2.3 Setting the Reactive-Power Meter Method"
Goes on when the displayed measurement is held.
Goes on when the medium for saving data is set to PC card.
Flashes when the PC card is accessed.
Goes on when the medium for saving data is set to internal memory.
Flashes when the internal memory is accessed.
Goes on when the PC card or internal memory is full.
Goes on when the device to be connected to the RS-232C is set to PC.
Goes on when the device to be connected to the RS-232C is set to
printer.
Goes on when the PLL is unlocked; the synchronization method is auto-
matically switched over to the fixed clock.
Instruction manual "5.2.2 Setting the Synchronization Method"
Goes on when the keys are locked.
Goes on when the voltage or current dynamic range is exceeded.
Displayed when the range is exceeded.
Reference U3* and I3* indicate that the data is obtained by calculating the
2-voltage, 2-current measurement results when 3P3W2M (three-
phase, 3-wire, 2-power-meter method) is selected.

6Power 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 well 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 measurereactive 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)
