ABSTRACT:
An electronic instrument with a housing having a battery compartment. The housing has a probe connector oriented on a probe axis, so that a probe may be connected to the instrument via the connector for interfacing with a device under test. A removable battery cover encloses the battery compartment, and has a probe aperture registered with the probe connector, so that a probe may be connected when the battery cover is installed. To prevent removal of the battery cover when a probe is connected to the probe connector, the battery cover is constrained against movement along the probe axis. In addition, the battery cover may contain a conductive safety element necessary to complete a circuit between the battery and other components in the instrument, so that the batteries are capable of delivering power only when the cover is properly installed.
