Abstract
A digital multimeter includes a body having a function selector and a first coupler and includes a head having a display and a second coupler. The function selector selects a parameter to be measured, and the display displays a measurement corresponding to the parameter to be measured. The first and second couplers are engaged in a first arrangement joining the body and the head, and the first and second couplers are disengaged in a second arrangement separating the body and the head.
Claims24
A digital multimeter, comprising:
- a body including a first coupler, the body having a back side, and the body being configured to select a parameter to be measured;
- and
- a head having a front face portion including a display, the head further including a second coupler, the display being configured to display a measurement corresponding to the parameter to be measured, wherein the front face portion and the second coupler are on opposite sides of the head,
- wherein the first and second couplers are configured to be engaged in a first rail/slot arrangement joining the body and the head,
- wherein the first and second couplers are configured to be disengaged in a second rail/slot arrangement separating the body and the head,
- wherein the digital multimeter is operational in both the first rail/slot arrangement and the second rail/slot arrangement, and
- wherein the second coupler is positioned beneath the front face portion of the head when the digital multimeter is in the first rail/slot arrangement, the back side faces downward, and the display faces upward.

A digital multimeter, comprising:
- a body including one or more receivers or projections, the body having a back side;
- and
- a head having a front face portion including a display, the head further including one or more projections or receivers corresponding to the receivers or projections on the body, wherein the front face portion and the one or more projections or receivers are on opposite sides of the head,
- wherein the body and the head are configured to be separated and rejoined through the corresponding projection/receiver pairs,
- wherein the digital multimeter is operational when separated and when rejoined, and
- wherein the one or more projections or receivers are positioned beneath the front face portion of the head when the front face portion is facing upward, the back side is facing downward, and the head and the body are rejoined.
3 more elements
A method of remotely displaying a measured electrical parameter with respect to measuring the electrical parameter, the method comprising:
- disjoining a display with respect to a sensor, the display being configured to display the measured electrical parameter and the sensor being configured to measure the electrical parameter, the display and the sensor being configured to be joined and disjoined by a lap joint, wherein the display is coupled to a first power source;
- individually powering the display with the first power source;
- and
- communicating the measured electrical parameter from the sensor to the display,
- wherein the display and the sensor are configured to be operational when disjoined and when joined, and
- wherein the first power source is configured to not be visible when the display and the sensor are joined and to be visible when the display and sensor are disjoined.
3 more elements
A digital multimeter, comprising:
- a body including a first coupler;
- and
- a head including a display, a power source that is separate from the body, a panel for accessing the power source, and a second coupler for engaging with the first coupler of the body to join the head with the body,
- wherein the panel is not visible when the head is joined with the body and the panel is visible when the head is separated from the body, and
- wherein the digital multimeter is operational when separated and when rejoined.
2 more elements
A digital multimeter, comprising:
- a body including a first coupler and a first power source;
- and
- a head including a display, and a second power source, and a second coupler for engaging with the first coupler of the body to join the head with the body,
- wherein the body is individually powered by the first power source and the head is individually powered by the second power source,
- wherein the second power source is not accessible when the head and the body are joined and the second power source is accessible when the head and the body are separated,
- wherein the digital multimeter is operational when separated and when rejoined, and
- wherein the first and the second couplers are selected from a group consisting of rail/slot, projection/receiver, lap joint and butt joint, or a combination thereof.
