Schlumberger 7062 Digital Multimeter
Hersteller:
Schlumberger
Modell: 7062
Datum: 1988
Kategorie: Messgeräte
Gruppe: Digital Multimeter
Beschreibung: SYSTEMS VOLTMETERS
Informationen:
                                    The 7061 System Voltmeter contains four printed circuit
boards (PCBs) which contain the electronic circuitry.
Additional option boards may also be fitted.
All inputs to the instrument are converted to a dc voltage
level and then transformed into time analog pulse trains on
PCB 15. On PCB 13, the analog pulse trains are digitised
into discrete, equal length time units, which are counted
and passed to the display board, PCB 1, for display. The
display provides a numerical indication of the input value
measured.
