description PCT No. PCT/EP94/00534 Sec. 371 Date Sep. 13, 1995 Sec. 102(e) Date Sep. 13, 1995 PCT Filed Feb. 25, 1994 PCT Pub. No. WO94/21994 PCT Pub. Date Sep. 29, 1994The invention relates to a process for operating a controlled heat conductance vacuum gauge with a measuring cell (18) comprising a Wheatstone bridge (1) with supply voltage (12, 13) and measurement voltage terminals (14, 15), a power supply and measuring instrument (21) and a connecting cable (19) containing several conductors and to a circuit therefor; in order to prevent errors of measurement caused by connecting cables (19) of different lengths and to automate cable length equalization it is proposed that the voltage of a power supply terminal (12, 13) of the Wheatstone bridge (1) in the measuring cell (18) be recorded without current via one (26) of the conductors of the connecting cable (19) and taken into account in the formation of the measurement value.
