Enhanced voltmeter leads includes load circuitry having a test load that can be switchably coupled between the leads to help identify faults in a circuit under test. In certain embodiments, the value of the test load can be any appropriate value set according to parameters or characteristics of the circuit under test. In these embodiments, the value of the test load can be set manually or automatically or both. The types of faults that can be identified include a short-to-ground, an open circuit, and a high (e. g. , corrosive) resistance. The leads include a switch whose setting is adjustable to couple and decouple the test load between the leads. The switch can be located in the leads or in a lead handle of the leads for easy access by a user/technician. The leads can also include a fuse or circuit breaker for safety reasons. The leads can be used systematically to help identify the type and location of a fault from voltage readings.

Provided is a cooking surface that incorporates a reverse-image decorative design so that when a foodstuff is prepared on the cooking surface, the design is transferred to the foodstuff. When the foodstuff is placed on the cooking surface, the foodstuff rests upon the decorative design element. A heat source applied to the cooking surface cooks the foodstuff such that, when food stuff is finished cooking, an image of the design element is displayed upon the foodstuff. By means of the present invention, a restaurant can impress, or “print,” a logo or message upon a steak, hamburger or other food product. A business owner can display a trademark on a food product for promotional purposes, a parent can place a cartoon character on a child's meal to encourage the child to eat the meal, and a stadium owner can place a local sport team's logo on a hamburger or hot dog.

Provided is a caliper extender (), which fits over a tape measure blade (), enabling accurate measurements to be taken of an inside dimension (). Extender () slides along blade () and is positioned against one wall of the inside dimension (). Blade () is then repositioned flat against extender () and a measurement reading is taken. A pointer () may also be incorporated into extender () to indicate a tape marking ( or ) corresponding to an accurate measurement. In the alternative, a caliper extender () is incorporated into a tape measure () such that extender () can be disengaged from a casing () of tape measure (), slid along a blade () and a measurement reading taken through a window () in a channel () through which blade () is installed.
