Extech's CT70 AC Circuit Load Tester analyzes outlet circuit wiring conditions
Extech Instruments' CT70 AC Circuit Load Tester is a plug-in tester that is engineered to analyze outlet circuit wiring conditions and alert users to conditions that are potentially hazardous or detrimental to power quality.
Extech’s CT70 is designed to inspect and detect circuit and wiring problems such as poor ground impedance, false grounds, missing ground fault protection, low voltage availability under load and high ground-to-neutral voltage. In addition, the CT70 tests GFCI and EPD circuits. The color-coded display changes from blue to red, providing a visual alert when a problem is detected.
As an AC load tester, the CT70 provides selectable loads of 12, 15 and 20 amps. Both loaded and unloaded AC line voltage are measured, as well as voltage drop percentage, line impedance, peak line voltage and frequency. Outlet tester functions include: GFCI trip time and current measurements; neutral-to-ground voltage testing; hot, neutral and ground impedance testing; and open or reversed wiring detection.
