Measurement Preparations
3.5 Connecting the Voltage Cords
33
Because the channel 4 input terminal is isolated from the other
inputs, it can be used for the following types of measurement.
• Measuring voltage on the neutral line in the same system
• Measuring line voltage in another system
• Measuring DC power
3.5 Connecting the Voltage Cords
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 cable 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 cable clips to touch two wires at
the same time. Never touch the edge of the metal clips.
• For safety reasons, when taking measurements, only use the
9438-02 VOLTAGE CORD provided with the product
• The supplied voltage cords consist of one each red, yellow, blue
and gray cords, and four black cords. Connect only the cords
actually needed for measurement. Cords not being used for
measurement should be disconnected.
Insert plugs all the
way in.
1. At each end of each cord,
apply the labels that corre-
spond to the (same-color)
input terminal to which it is
to be connected.
2. Insert each voltage cord
into the input terminal of
the same color.
