between the MM-400A and Measurement Devices
a. Connecting the Toroidal Coil and the Voltage Detection Cable
To measure the current or voltage, connect the toroidal coil and the voltage
detection cable to the rear panel of the MM-400A.
Toroidal coil (e.g., MB-400M)
Connect a toroidal coil suited to your operating environment.
The toroidal coils of the following sizes can be used:
Toroidal coil model Type
MB-800M 1x sensitivity coil (with 800 mm bracket), ISO-compliant
type
MB-400M 1x sensitivity coil (with 400 mm bracket), ISO-compliant
type
MB-800K (Note) 1x sensitivity coil (with 800 mm bracket)
MB-400K (Note) 1x sensitivity coil (with 400 mm bracket)
MB-45F (Note) 10x sensitivity coil (mold type)
(Note) Optional toroidal coil conversion cable SK-1193305 is required.
Follow the steps described below to connect the toroidal coil and the voltage
detection cable.
1) Plug the toroidal coil’s connector into the toroidal coil connector [COIL] on the
rear panel of the MM-400A.
