• Inserting the display module 350 via a display circuit assembly 351 of the display module 350 from a display module receiving opening 443 of the front unit 430 in an engaging orientation such that an obstructing projection 369 of a display panel 360 getting accommodated in a clear zone 444 of a peripheral wall 442 of the front unit 430,
• Pushing in the display module 350 till a projection 368 of a display module engager 364 getting trapped in a locking slots 447 of the front unit 430, and at this instance a plug-in female electrical connector 353 of the display module 350 precisely engaging till a defined engagement dimension 420 with a corresponding set of plug-in male electrical connector 393 on the programmable computing receptacle assembly 390,
• Inserting a battery module 380 in a longitudinal through slot 462 of the battery module receiver arrangement 461 of the front unit 430 after engaging a guiding projection 384 of a battery carrier 381 in an extension slot 463, thus ensuring that a polarized module cover 383 is aligning with a polarized seat 464,
• Pushing the polarized module cover 383 of the battery carrier 381 till a click-fitting provisions 385 “click” into a click-locking slot 465;
• thus ensuring that a cantilever arm 438 is supporting a commensurate battery cell 389 while a first contact surface 387 and a second contact surface 388 making an electrical contact with a battery cell connector 395 on the programmable computing receptacle assembly 390 with a requisite contact pressure.

A process of preparing a group of electrical devices 10 for measurement, control and display of electrical and process parameters comprising a second sub-group 12 of electrical devices, each member of electrical device of the second sub-group 12 comprises a neck mountable enclosure unit 22, a programmable computing receptacle assembly 390 and a plurality of function modules 300, the process comprises the steps of:

• Selecting a plurality of function specific function modules 300 and a display module 350,
• Inserting a programmable computing receptacle assembly 390 in a housing 530, in a pair of major parallel tracks 538 via a major entry chamfers 539 on each track, on a bottom wall 532, sliding the programmable computing receptacle assembly 390 past a plurality of locking clicks 534 and resting on a plurality of stoppers 535,
• Inserting a function circuit assembly 310 of the function module 300 in a pair of minor parallel tracks 552 of a functional unit receiver arrangement 551 via a minor entry chamfer 553 on each track,
• Pushing in a fixation cap 320 till a frontal locking means 328 gets trapped in a frontal locking slot 557 of a top wall 533 or a bottom wall 532 or a backward wall 554 of the housing 530, and simultaneously, a constraining female projection 326 of a first bridge 325 engaging with a constraining male projections 555 of a corresponding backward wall 554, and a locating female orifice 327 of a second bridge 322 engulfing a locating male projections 556 on the housing 530;
• and thus ensuring that a set of plug-in male electrical connectors 312 of the function module 300 precisely engages till a defined engagement dimension 420 with a corresponding set of plug-in female electrical connector 392 on the programmable computing receptacle assembly 390,
• Inserting a door panel unit 550 via a door display circuit assembly 501 of the door panel unit 550 from a circuit assembly receiving opening 573 of the housing 530 in an engaging orientation,
• Pressing in the door panel unit 550 by seating an external frame 515 of a bezel 500 around an internal frame 581 of the housing 530, and dropping a plurality of door unit entrapment means 516 in a plurality of unit fixation means 582, and at this instance a set of plug-in female electrical connector 503 of the door panel unit 550 precisely engaging till a defined engagement dimension 420 with a corresponding set of plug-in male electrical connector 393 on the programmable computing receptacle assembly 390,
• Inserting a battery module 380 in a transversal through slot 562 of a battery module receiver arrangement 561 of the housing 530,
