The ST800PGN puts a high magnitude pulse between the neutral/hot leg or hot leg/hot leg for any secondary service (120V, 208, 277, 480V). It cannot be fooled by telephone and cable television bonding often missed by continuous loading devices.
The ST800 Digital All Purpose Secondary Service Tester is designed to replace numerous meters that incorporate single range or function. Each tester has two buttons for ease of use on system voltages ranging from 90 volts to 500 volts (phase-to-phase).
The digital meter is capable of reading AC voltages as well as AC Current from 10 to 800 Volts/Amps. The ST800 kit consist of an ST800 large backlit LCD digital meter contained in plastic injection molded housing, a STRCV receiver probe for indicating signal strength and direction, cable assemblies, and a digital laser pyrometer for identifying poor service connectors. Improved voltage range and output signal creates an all purposed device that identifies the good and bad conductors without being fooled by parallel neutral paths.
