Special Tariff Meters TRIZ Cases

Generated current is reused as both output and internal source, avoiding high-performance current mirrors while improving conversion accuracy.

Converts bipolar electrical measurements into audio frequency and waveform cues, freeing visual attention during circuit adjustment.

Multiple measurement circuits and coded device channels integrate power and analog sensing data for scalable energy monitoring.

Coded signal transmission requires authorized physical presence to restore gas flow, resolving safety risks from unauthorized remote reconnection.

A detection method calculates squared differences between measured and imputed neutral currents to identify electrical energy loss.

Convex portions on the rotary switch rotate shutter plates to open specific terminal holes, preventing erroneous probe insertion without complex linkages.

Sequential detection routines identify component types to eliminate manual function selection errors.

Rotary switch memory restores non-default measurement functions automatically, reducing selection complexity and improving data management.

A multiplexer routes a reference signal to shared gain stages for simultaneous auto-zero calibration across all measurement ranges.

A mobile functional unit detects connection device identifiers and measures electrical energy flow without fixed infrastructure.

A digital multimeter transmits measurement data by modulating its backlight LED intensity for remote optical detection.
