Connect the L9438-53 voltage cords to the instrument’s voltage input terminals while
checking the [WIR, DIAG] screen. The instrument ships with one each of the black,
red, yellow, and blue voltage cords and alligator clips as well as five spiral tubes.
Group the cords together with the spiral tubes as necessary.
See: "Bundle the Voltage Cord Leads with the Spiral Tubes" (p. 22)
Preparation items
3.3 Connecting the Voltage Cords
• To avoid electric shock and short-circuit accidents, use only the
specified L9438-53 Voltage Cord to connect the instrument volt-
age input terminals to the circuit to be tested.
• To ensure voltage cord integrity, grip cords by the plug when
connecting o
r disconnecting them.
