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

Two methods for performing 3-phase/3-wire power
measurement
• 3-phase/3-wire/2-meter (3P3W2M) method:
Power is calculated from two sets of voltage and current values (use for
normal measurement).
• 3-phase/3-wire/3-meter (3P3W3M) method:
Power is calculated from three sets of voltage and current values (use
when you wish to verify each phase’s power balance).

Quick Start Manual
What is VT ratio?
VT is used in high-voltage measurement to convert (step-down) the voltage
measured to a smaller level and supply the conversion result to an instrument.
VT ratio (voltage transformation ratio): A ratio used to convert the secondary voltage of VT to the primary voltage.
Example
When the primary voltage is 6600 V and the secondary voltage is 110 V, the VT
ratio is 60 (6600 V/110 V). In this case, as the rated measurement voltage is 110
V, set the voltage range to 150 V.

Clamp sensor and current range:
Selectable current ranges vary according to the clamp sensor used.
Choose a clamp sensor head as appropriate for the measurement target.
Clamp sensors Range
Model 9660, 9695-03 5 A, 10 A, 50 A, 100 A
Model 9661 5 A, 10 A, 50 A, 100 A, 500 A
Model 9667-5kA (5000 A range) 5 kA
Model 9667-500A (500 A range) 500 A
Model 9669 100 A, 200 A, 1 kA

the maximum rated
current
Reference
When using the CT9667 sensor,
choose “9667” for the sensor on
the Measurement Setting screen.
3
What is CT ratio?
CT is used to measure large current to reduce the current measured to a
smaller level and supply the conversion result to an instrument.
CT ratio (current transformation ratio): A ratio used to convert the secondary current of CT to the primary current.
When the primary current is 100 A and the secondary current is 5 A, the
CT ratio is 20 (100 A/5 A). In this case, as the rated measurement current
is 5 A, set the current range to 5 A.

Choosing the current range
Set the current range based on your expectation of the maximum load current that
will flow during the measurement period. (Select an appropriate range based on factors such as the operating state, rated load, and breaker rating.) When the range is
too low, an over-range event will occur during measurement, preventing accurate
measurement. When the range is too high, the magnitude of the error component
will increase, preventing accurate measurement.

The wiring check result is NG.
Check the following:
Issue What to check Reference
The voltage
input is NG.
• Are you sure that the voltage clip is connected to the
metallic part of the object to be measured?
(p.19)
• Is the voltage cord properly inserted into the voltage
input terminal of the 3169?
(p.11)
• Is the voltage cord properly inserted into the voltage
clip?
(p.10)
The current
input is NG.
• Is the clamp-on sensor securely inserted into the
cur-rent input terminals?
(p.12)
• Is the set current range too large for the input?
If the current range is too large, change the current
range setting to a lower range to have the measurement values more than 5% of the set range.
(p.21)
The voltage
phase is NG.
• Are the voltage cords properly connected?
(To both the object under measurement and the
instrument)
(p.11)
(p.19)
The current
phase is NG.
• Does the current flow direction arrow of the clampon sensor point to the load side?
(p.19)
• Are the clamp-on sensors properly connected?
(To both the object under measurement and the
instrument)
(p.12)
(p.19)
The phase
difference (I-U)
is NG.
• Are the voltage cords and clamp-on sensors properly connected?
(To both the object under measurement and the
instrument)
(p.11)
(p.19)
• Does the current flow direction arrow of the clampon sensor point to the load side?
(p.19)
• Is the power factor of the line to be measured 0.5 or
less? If the power factor is less than 0.5, the phase
difference (I-U) will show NG even if the wires are
properly con-nected.When the connection is visually
confirmed as being appropriate, the measurement
values will be correct even if a NG judgment is given.
−
The voltage balance is NG.
• Does the connection method of the line to be measured differ from that set?
(p.15)
• Are you sure that the voltage clip is connected to the
metallic part of the object to be measured?
(p.19)
• Is the voltage cord properly inserted into the voltage
input terminal of the 3169?
(p.11)
Reference
The wiring check function may indicate improper connection
("NG") even when the actual wiring is correct, or vice versa.

Interrupt Measurement
Press the key. The message "Do you want to stop the time-series
measurement?" is displayed for you to confirm. Press the (yes) key.
If the message “This key cannot be selected.” is shown, press the key
to display the Measurement screen and then press the key again.
All measurement data before the interruptions saved on the PC card if the
measurement is interrupted.
Stop Measurement
The 3169 will automatically stop measurement at the stop time. The measurement data has been saved on the PC card.

Power Measurement
Shutdown Procedure
1. Disconnect the voltage cords and clamp-on sensor from
the measured line.
2. Turn off the power to the 3169.
3. Disconnect the power cord from the AC outlet.
4. Remove the PC card from the 3169.
5. Copy the data on the PC card to the PC.
6. Analyze the saved data on PC.
You can analyze data on a PC with the optional SF1001 Power Logger
Viewer. Additionally, data is saved to a CSV format file (p.25) when the interval setting is 1 sec. or greater, allowing that data to be loaded into a commercial spreadsheet application such as Excel*.
