Using A Clamp-On Sensor (Option) - Hioki 3169-20 Instruction Manual

3.4 Using a Clamp-On Sensor (Option)

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
• When the clamp sensor is opened, do not allow the metal
• To prevent damage to the product and sensor, never con-
