Digital Leakage Current Tester
Educated Design & Development, Inc.
Fast - All operator controls are located on the front panel to expedite testing. The entire test can be performed in a matter of seconds! Pays for itself in time and stress savings. Versatile - Measures Leakage Current in accordance with UL, CSA, EN, and IEC/ International Standards. Includes ability to perform open neutral, open ground, and line polarity forward/reverse test conditions. Adaptable - Universal rear panel receptacle allows for testing products with any plug configuration. Accurate - True RMS meter accurately measures both sinusoidal and non-sinusoidal waveshapes. This is important when testing products using a switch mode power supply which can generate non-sinusoidal leakage currents. Calibrated, traceable to NIST. Flexible - A front panel switch permits testing either through the power cord of the product under test, from surface/ patient connection-to-ground, or from surface/ patient connection-to-surface/ patient connection. Portable - Lightweight, with integral handle. Other Features - Product Ground Switching (grounding conductor maintained to device under test when not measuring leakage). Automatic front receptacle disconnect when configured in the 240V test mode (prevents inadvertent connection of 120V when configured for 240V operation). Proven - These are the only leakage current testers designed and supported by Product Safety experts. That is part of the reason why they have become the standard in the industry. Full technical support by experienced safety engineers.
