PS100 Lhtweht 28V Power Supply Powervamp The Historical Section of the SAIEE has many artifacts of historical interest in its collection and has an association with Eskoms historical collection. Lhtweht 28V DC power supply, fitted with solid state voltmeter and ammeter, capable of providing 100A continuous power for avionics use.
How do they work? 2. Voltmeters Further detailed information on each artifact can be viewed by clicking on the image of the selected items shown below, JOHANNESBURG OBSERVATORY LHTNING RECORDER Manufactured in Budapest 1905 This remarkable lhtning recorder is the only surviving instrument from the Transvaal Meteorological Station at the Johannesburg Observatory. Unlike an ammeter, however, an ideal voltmeter consumes as little. calibration accuracy has not been checked. 21 shows an early Weston 150/3OOV.
Instruction and Maintenance Manual Its operation was based on the Marconi coherer wireless telegraphy receiver. Maintenance Manual. Four ranges are provided, 0-.5, 0-5, 0-50 and 0-500 Brill-l.

AN AC/DC PORTABLE WATTMETER manufactured in the USA by Weston. Range 0,1 – 1,8 ohms Detailed operating instructions are shown on the inside lid.
Experiment 19： Ammeter, Voltmeter, and Ohmmeter Lhtning impulses induced in an external antenna caused the coherer to conduct and operate the telegraph relay situated on the rht hand side of the instrument. The instrument is part of the South African Institute of Electrical Engineers historical collection and can be viewed in Observatory, Johannesburg, South Africa. Common polarity-sensitive movements include the D'Arsonval and Weston desns. than 1000 Ω. This makes for a voltmeter with a full-scale rating of only 50.
