External safety interlock (for Caged Operation)
If cables are to be tested in a caged area with the FL-20A located out-

so that cables may be tested only when the cage door is closed. When
the external interlock is engaged and the Caged Operation setting, found
in the Settings menu, is ON, the operator will be required to momentarily
press the FL-20A safety buttons during a test, rather than press them for

The safety interlock is also required for calibration. A two-position con-
nector is supplied for this purpose. Refer to the Calibration section for
instructions.

operator from touching the charged test cable during a test.
Red and blue test probes

probe to the opposite end. Review the instructions in the Installation
section on how to properly strip back the conductors and insert them
