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.

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.

3. Connect the power cord.
To avoid electrical accidents and to maintain the safety spec-
ifications of this instrument, connect the power cord pro-
vided only to a 3-contact (two-conductor + ground) outlet.

4. Connect the Voltage cord to the voltage input terminals of
the 3169.
• Connect the voltage cords to the instrument first, and then
to the active lines to be measured.
Observe the following to avoid electric shock and short cir-
cuits.
• Voltage cord should only be connected to the secondary
side of a breaker, so the breaker can prevent an accident if
a short circuit occurs. Connections should never be made
to the primary side of a breaker, because unrestricted cur-
rent flow could cause a serious accident if a short circuit
occurs.
• Do not allow the voltage cord clips to touch two wires at the
same time.
Never touch the edge of the metal clips.
• Voltage input terminals U1, U2, and U3are common to the N
terminal and are not insulated. To avoid the risk of electric
shock, do not touch the terminals.
• To prevent an electric shock accident, confirm that the
white or red portion (insulation layer) inside the cable of
voltage cord is not exposed. If a color inside the cable is
exposed, do not use the cable.
For safety reasons, when taking measurements, only use the
L9438-53 Voltage Cord provided with the instrument.
Insert plugs all the way in.

5. Connect the clamp sensor (Model 9661) to the current
input terminals of the 3169.
When disconnecting the BNC connector, be sure to release the
lock before pulling the connector. Forcibly pulling the connector
without releasing the lock, or pulling on the cable, can damage the
connector.

6. Insert the PC card into the 3169.
Use only PC Cards sold by Hioki. Compatibility and perfor-
mance are not guaranteed for PC cards made by other manu-
facturers. You may be unable to read from or save data to
such cards.
• Inserting a PC card upside down, backwards or in the wrong
direction may damage the instrument.
• Never eject a PC card while it is being accessed by the instru-
ment. Data on the PC card may be lost.
• Some PC cards are susceptible to static electricity. Exercise
care when using such products because static electricity could
damage the PC card or cause malfunction of the instrument.
• With some PC cards, the instrument may not start up if power is
turned on while the PC card is inserted. In such a case, turn
power on first, and then insert the PC card. It is recommended to
try out operation with a PC card before starting to use it for
actual measurements.

7. Turn the POWER switch ON.
8. Adjusts the contrast of the screen as necessary.
Before turning the instrument on, make sure the supply volt-
age matches that indicated on it’s power connector. Connec-
tion to an improper supply voltage may damage the product
and present an electrical hazard.

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).

16 Power Measurement
Quick Start Manual
What is VT ratio?
VT is used in high-voltage measurement to convert (step-down) the voltage
measuredtoasmallerlevel andsupply theconversion resultto aninstrument.
VT ratio (voltage transformation ratio): A ratio used to convert the secondary volt-
age 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.
2
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
Model 9694 0.5 A, 1 A, 5 A
Model 9695-02 0.5 A, 1 A, 5 A, 10 A, 50 A
Model number and
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 second-
ary 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 (100A/5 A). In this case, as the rated measurementcurrent
is 5 A, set the current range to 5 A.
