The IDEAL Electrical 61-164 SureTest Circuit Analyzer utilizes patented technology to "look behind walls" and identify wiring problems that can lead to personal shock hazards, electrical fires, or equipment performance issues. Personal shock hazards stem from poor grounding, false grounds, and/or no ground fault protection. Electrical fires are primarily caused from arc faults and high resistance points that lead to glowing connections in the circuit wiring. And, equipment performance issues arise due to insufficient voltage available under load, poor ground impedance, and high ground-to-neutral voltage.

The 61164 analyzer takes only seconds to test each outlet and circuit under a full load. This test tool checks for various wiring conditions, including: correct wiring, polarity reversal and no ground per UL-1436. A simple menu gives access to measurements of line voltage, voltage drop under a full load condition, ground-to-neutral voltage, and line impedances. The ground fault circuit interrupter (GFCI) test is performed separately in accordance with UL-1436 and disrupts the electrical supply if a functional GFCI is present.
