Switchboard Instruments

HE Weston Electrical Instrument Company desires to particularly call attention to a new line of very cheap, but excellent Voltmeters and Ammeters for direct current circuits, which are designated as the

WESTON ROUND PATTERN

VOLTMETERS AND AMMETERS.

These instruments are based on the same principle as the wellknown" Weston" Portable Standard Instruments. Their "dead

beat character," an almost absolutely proportional scale, and the entire absence of " magnetic lag," are features not possessed by any other instrument in the market. Being encased in dust-proof iron cases, the instruments are thoroughly protected from disturbing influences of external magnetic fields. The instruments are free from heating errors and may be left in circuit continuously without impairing their accuracy.

CAUTION: Beware of specifications which are so drawn as to compel the use of the many wretched soft iron gravity instruments on the market. Whenever you find specifications so drawn you may rest assured that some one is more interested in forcing upon you inferior apparatus than in protecting you from continuous heavy losses, resulting from the great waste of power in such instruments. Correspondence solicited.
