2.3 Measurement Preparations

1. Connecting the Power Cord

• Before turning the product on, make sure the source volt­age matches that indicated on the product's power connec­tor. Connection to an improper supply voltage may damage
the product and present an electrical hazard.

• To avoid electric shock and ensure safe operation, connect
the power cable to a grounded (3-contact) outlet.

Connect the power cord to

2.3 Measurement Preparations

2. Connecting the Voltage Cords

15

Connect the voltage cords to the product first, and then to
the active lines to be measured. Observe the following to
avoid electric shock and short circuits.

• 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 cur­rent flow could cause a serious accident if a short circuit
occurs.

• Do not allow Do not allow the voltage cable clips to touch
two wires at the same time. Never touch the edge of the
metal clips. Never touch the edge of the metal clips.

• Voltage input terminals U
terminal and are not insulated. To avoid the risk of electric

shock, do not touch the terminals.

• For safety reasons, when taking measurements, only use the
9438-03 VOLTAGE CORD provided with the product.

• The supplied voltage cords consist of one each red, yellow, blue
and black cords. Connect only the cords actually needed for
measurement. Cords not being used for measurement should
be disconnected.

3. Connecting the Clamp-On Sensor

Connect the clamp-on sensors to the product first, and then
to the active lines to be measured. Observe the following to
avoid electric shock and short circuits.

• Clamp sensor 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 cur­rent flow could cause a serious accident if a short circuit
occurs.

• When the clamp sensor is opened, do not allow the metal
part of the clamp to touch any exposed metal, or to short
between two lines, and do not use over bare conductors.

• To prevent damage to the product and sensor, never con­nect or disconnect a sensor while the power is on.

• The current input terminals of the 3169-20/21 are not insu­lated. To avoid the risk of electric shock, only use the spec­ified optional clamp-on sensor.

2.3 Measurement Preparations

Use only PC Cards sold by HIOKI. Compatibility and perfor­mance are not guaranteed for PC cards made by other manu­facturers. You may be unable to read from or save data to
such cards.

• The PC card or the instrument can be damaged if the card is
inserted forcefully in the wrong direction.

• Never eject a PC card while it is being accessed by the instru­ment. Data on the PC card may be lost.

5. Turning the Power On

Before turning the product on, make sure the source voltage
matches that indicated on the product's power connector.
Connection to an improper supply voltage may damage the
product and present an electrical hazard.

Open the cover and insert the
