A measurement device providing a graphical user interface (GUI) to a user on a remote terminal comprising at least one first processor; and at least one first memory including one or more first sequences of instructions to perform the steps of transmitting a GUI displaying a at least one of a first, a second, a third, and a fourth image in response to at least one of a voltage characteristic, a current characteristic, and a load characteristic obtained from the user through the GUI on the remote terminal. Then, the measurement device stores in a memory the at least one of the voltage characteristic, the current characteristic, and the load characteristic.

Measurement device and method of its operation

A measurement device, such as a power meter or power submeter, may comprise a frame disposed in a housing dividing an interior volume of the housing into a first volume and a second volume. An external power source is connected to the device in the first volume and the frame may serve as an insulative barrier between the first volume and an exterior it and the housing. The device may alternatively, or additional include, an user interface assembly that is configured to mounted in a same orientation regardless of an orientation of the device or housing of a device relative to the external power source.

A surface mounted instrument () that is easily installed to seal () against a mounting surface () in spite of imprecise installation of a standard rough-in box () or irregularities in the surface. A cover plate () overlays the installed instrument housing () without the use of outwardly visible mechanical connectors by use of a pawl () that engages the housing. An oversized display () is mounted for easy replacement on a moveable display module () for unobstructed access to the interior () of the housing. Subsurface channels () formed in the housing are used to deliver a working fluid from a measured location to a sensor () inside the housing.

Surface mounted instrument

An environmental condition monitor () configured for simple upgrade from analog signal output to any of a plurality of digital communication protocols. A display board () includes the analog signal acquisition and processing elements of the device and also includes a pre-positioned but initially inoperative digital communication output connector (). A connector board () associated with the display board includes a connector () to which any one of a plurality of digital communication boards () may be selectively connected, depending upon which of a plurality of digital communication protocols is desired. Selective connection of a digital communication board completes a circuit whereby an analog output signal is converted to the desired digital output format and is then communicated back to the now-activated digital communication output connector ().

Environmental condition monitor for alternative communication protocols

An apparatus () for sensing a condition, such as humidity, through an opening () in a surface () such as a duct or wall. A housing () includes an outer section () mounted on the surface and a probe section () extending into the duct or wall. A circuit board assembly () is mounted within the housing and includes a user interface section () within the housing outer section and a sensor section () rigidly connected to the user interface section and extending into the housing probe section. The sensor section may be integrated into the circuit board assembly by a rigid connector () allowing easy removal and field replacement of the sensor section. A sealing device () isolates the housing outer section from the air within the duct or wall. A flexible grounding connection () provides electrical grounding of the circuit board assembly and a degree of mechanical support.
