Essential Info
The Extech CT70 AC Circuit Load Tester can 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.
Circuit and wiring issues listed above can introduce shock hazards (from grounding issues) and can comprise performance of machinery and equipment (from poor ground impedance, lack of sufficient voltage under load and/or high ground-to-neutral voltage). In addition, fire can result from the heat generated by high resistance points in a circuit.
Proper wiring habits have been shown to greatly increase power quality performance. This meter is shipped fully tested and calibrated and, with proper use, will provide years of reliable service.
The CT70 AC Circuit Load Tester can test outlets or circuits under load for proper wiring, reverse polarity, and the presence of a ground. The CT70 uses a simple menu-driven display to allow the user to quickly see line voltage, voltage drop under full load, ground-toneutral voltage, and line impedance. The GFCI testing utility is performed separately per UL-1436, disrupting the flow of electricity if a functioning GFCI is present.
