Service Ground Test Set

900 - The Eastern Specialty Company (TESCO)

TESCO’s Service Ground Test Set has been designed to check the condition of the ground connection on a secondary service. If for any reason the ground connection has a resistance, this can be immediately detected by the Test Set. The Service Ground Test Set consists of a voltmeter which can be shunted by a resistance of 60 ohms. The voltmeter is of the suppressed zero type with a double range, from 65 to 130 or from 130 to 260, and can be used for checking service voltage independently of the ground test.
