ABSTRACT:
The ammeter includes a tubular housing with a hook-shaped sensor secured thereto at one end thereof and coupled to battery-powered digital ammeter circuitry disposed within the housing. The other end of the housing is open and receives telescopically therein a cylindrical cartridge which includes either a cradle or a recess supporting a replaceable battery and carrying connectors for connecting the battery to the ammeter circuitry. A universal spline coupler is telescopically received in a bore in the cartridge and projects from the tubular housing when the cartridge is disposed therein for coupling to associated equipment, such as a hot stick.
