Display with backlight, hold, sleep modes Large direct-reading displayof Chance Digital Phasing Testers easily determine phase relationshipsand approximate voltage, line-to-line or line-to-ground. Each testerconsists of two fiberglass poles with end fittings threaded forinterchangeable probes. The probe fittings couple with a high-impedancecomponent encased in each pole. To complete the test circuit, a 22-footlength of insulated flexible cable stores on the reel affixed to onepole and connects to the electronic display module on the other pole.Simple to operate,the tester attaches to two 6-foot Epoxiglas insulatinguniversal handles (included in each kit for proper working clearances).Then the probes can be brought into contact with the conductorsappropriate for the tester to display phase-to-phase or phase-to-groundvoltage. Pushbutton controls permit easy selection of options fordisplay Backlight and Hold features. When not in use, the unit?s Sleepmode automatically conserves the battery.
