Product Description

Welcome to use our instrument. Please check the accessories by referring to the list of attachments after the instruction after opening the instrument package. Please read this instruction carefully before use. I. OverviewThe MS2621GNS series leakage current tester is mainly used to detect leakage current of medical equipment or laboratory standard equipment. The instrument applies to the detection of the earth leakage current, housing leakage current, patient leakage current, patient leakage current (applied voltage test of signal part), patient leakage current (applied voltage test of applied part) and patient auxiliary current (DC and AC) of medical electrical equipment in various types (class I, class II, internal power supply and B type, BF type, CF type). The instrument meets the standard test requirements of Medical Electrical Equipment Part I – General Requirements for Safety (GB9706.1) and Safety Requirements For Laboratory (GB4793.1), and is the essential safety regulation test instrument for medical device manufacturers and test authorities. Main characteristics:1. It can set test items according to the category, such as automatically combining the tests in the same test item, and synchronously displaying the measured voltage value, external voltage value, normal state leakage current value, and single fault state leakage current value;2. It can complete the tests of earth leakage current, housing leakage current, patient part leakage current (applied network power voltage test of applied part), patient leakage current (DC and AC) and other items by pressing one button, and test them separately;3. It has the power supply circuit overvoltage and overcurrent protection, MD measuring device overcurrent protection, and leakage current over-limit acousto-optic alarm function. 4. It has PLC interfaces for external control; it has an RS232 interface to upload test data in real time. II. Main Technical Indicators and Parameters1. Working environment:a. Temperature :0℃ – 40℃b.
