The ESA620 Electrical Safety Analyzer represents quality excellence in manual preventive maintenance for the biomedical technician and clinical engineer that perform tests on medical equipment. With selections of three test loads, protective earth test currents, and two insulation test voltages this versatile product can be used worldwide to test to their standard of choice. Equipped with ten ECG posts, the ESA620 simulates of ECG and performance waveforms so both electrical safety and basic tests on patient monitors can be performed with a single connection. This full-featured electrical safety analyzer comes standard with test leads for 2-wire protective earth measurements, and with optional leads offers the time-saving 4-wire technique. Additionally, the 25-A-device receptacle allows for testing of those devices that need it, so the technician is not limited to only test 15-A equipment. (US only) New DSP technology offers better accuracy of leakage measurements throughout the ranges specified in the standards, and an intuitive interface guides the user through tests. The ESA620 features a large display to facilitate quick and clear indication of performed tests, criteria associated with test set up, device under test receptacle conditions and results. The unit is equipped with standard USB interface for computer control and data transfer. When used with optional Ansur computer-based software Plug-in, the ESA620 allows for standardization of test procedures, as well as result capturing, storage and printing of reports. When combined with Ansur, the ESA620 can be automated, capturing results and comparing them to standard limits, essentially enabling this manual unit the sophisticated performance of high end electrical safety equipment at half the price.
