## Description

LCD Circuit Analyzer, AC100-240V RMS Circuit Analyzer Tester MS5908A/MS5908C LCD Circuit Analyzer, Voltage GFCI RCD Fault Tester (MS5908A US PLUG) - desertcart.com

Review: Great tool to thoroughly check your household outlet wiring - Since this tool will do loaded impedance tests of line, neutral, and ground, it found a ground problem that the typical LED-based testers said all was fine. We have outlets in the shop that use the conduit as their ground and the continuity of the conduit was not very good on a couple of them. This tester immediately identified the bad outlets in the shop so we could figure out where to look for incorrect conduit connections. Great little tool. Manual kind of useless, but fairly easy to figure out how to run it without a manual
Review: Load test is very inaccurate. - This product comes with a long cable that creates significant voltage drop which results in very inaccurate load results. When I replaced the cable with that of the Klein Tools RT390 the voltage drop for 20A went down by about 9%. Replacing the cable with a high current 1' cable (available on desertcart) may improve the accuracy. The product provide very detailed information, compared to the Klein Tools RT390, but is more complex to use and is significantly less accurate. I am returning this product and will keep the Klein Tools RT390.

## Features

- Multifunctional: This voltage circuit analyzer offers various features such as backlighting and data retention functions. These functions make it easy to read and operate, even in low light conditions, and allow for convenient data storage.
- Widely Used: The LCD Circuit Analyzer is versatile and can be used for TRMS measurement of AC voltage. It is also capable of testing the reliability and response time of residual current devices (RCDs) and the reliability of Ground Fault Circuit Interrupter (GFCI) action. This makes it suitable for a wide range of electrical testing and troubleshooting applications.
- Manual Load: The analyzer comes with manual load options for different current levels. This allows for measuring wire drop at 12A, 15A, and 20A (MS5908A model), or at 5A, 8A, and 10A (other models). This feature enables accurate measurements and assessment of wire performance under different load conditions.
- Measurement Range: This circuit analyzer is capable of measuring various parameters including phase voltage, neutral line voltage, ground voltage, peak voltage, frequency, and impedance of phase, neutral, and ground wire conductors. This comprehensive measurement range allows for thorough analysis and evaluation of electrical circuits.
- Connection Mode: The analyzer can identify the 3-wire socket connection mode, determining if the left side is neutral, the right side is live, and whether there is a grounding wire. This feature helps in verifying proper wiring connections and ensuring electrical safety.
