Patent attributes
An electrical meter 10 comprises a housing 12 with a spool 14 rotatably mounted therein. A first lead cable 16 and a second lead cable 18 are wound upon the spool 14. A wound spring 90 is connected to the spool and biases the spool against rotation in a direction that allows the lead cables to be unwound. A first head 20 and a second head 22 are respectively included on the end of the first lead cable 16 and the second lead cable 18. The heads abut against the housing and prevent the lead cables from being completely wound upon the spool when the meter is not in use. A circuit board 30 with electrical measurement circuitry is also mounted within the housing 12. The circuit board is electrically connected to a display 40 positioned on the outside of the housing 12.
