MFK1 and MFK2: Notes
The MFK1 and MFK2 cables are the main leads used for measurements. They are similar in appearance, but have different measurement capabilities.
Only one cable, either MFK1 or MFK2 (visual markings) may be connected to the control panel at one time unless a Measurement Interface Box (MIB) is used.
Both large positive cable ends of MFK1 and MFK 2 include a button used to hold the measured value on the display screen.
