The ESA620 Electrical Safety Analyzer represents the next generation in portable, manual electrical-safety testers for the biomedical technician and clinical engineer that are performing 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: IEC60601-1(partial), ANSI/AAMI ES60601, IEC62353, VDE 751, ANSI/AAMI ES1:1993, NFPA-99, AN/NZS 3551, IEC61010.
This multifaceted device performs all primary electrical safety tests, including mains voltage, protective earth resistance, insulation resistance, device current, earth, chassis, and patient leakages as well as several additional leakage tests to comply with EN62353. It comes standard with test leads for 2-wire protective earth measurements, and with optional leads offers the time-saving 4-wire technique. Additionally, the 20-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.
Equipped with ten ECG posts, the ESA620 offers simulation of ECG and performance waveforms so both electrical safety and basic tests on patient monitors can be performed with a single connection. 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 becomes automated, capturing results and comparing them to standard limits, essentially enabling this manual unit the sophisticated performance of the high end models at half the price.
