Période

late 1970's to mid 1980's

Canada

An instrument of a type used by the Meteorological Service of Canada, probably in its calibration laboratories. Part of a large collection of meteorological instruments acquired from the Meteorological Service of Canada (previously Atmospheric Environment Service) by the CSTM since 1967. MSC is the government agency responsible for collecting and disseminating meteorological data and forecasts in Canada. It was founded in 1871 in Toronto where it is still headquartered. The MSC was originally on the University of Toronto downtown campus but moved to Downsview in 1971 on land owned by UofT. The headquarters houses laboratories, research facilities and calibration and instrument maintenance facilities (now largely contracted out).

Fonction

An instrument used in standards laboratories to measure DC voltage, AC (RMS) voltage and resistance.

Technique

The model 9577 is a long scale digital multimeter (or DMM for short). These were the world's first high accuracy digital DMM's, introduced probably in the late 1970's and lasted to the mid 1980's. It was used to measure resistance and DC/AC voltage signals, it was also used in standard laboratories (Ref. 2). A precision voltmeter that measures DC voltage [continuous range from 1 microvolt to 1 kV]; AC (RMS) voltage [continuous range from 1 microvolt to 750 V rms (1.1kV Peak)]; and resistance [continuous range from 1 m ohm to 12 M ohm]. It directly measures rms: the input is directly converted to its root mean square at the measurement stage so that the displayed reading is precisely computed rms value of the alternating quantity being measured (Ref. 1).
