This device is designed to perform simple electrical safety tests on any type of medical equipment, whenever patient lead testing is not required.
The rugged, hand-held instrument is built for quick and easy use. A simple selector knob controls the functions: Leakage Current and Chassis Resistance. Accurate test measurements are shown on the large display.
Heavy-duty switches change polarity, open and close the neutral and select Chassis or Earth Leakage Current measurements. A four-wire Kelvin bridge eliminates reading errors in resistance due to cable length and contact resistance. True RMS measurements are provided for all current readings. The AAMI test load is utilized.
- Small, lightweight, self-contained portable instrument
- Universal Power Supply. Input voltage from 85 - 265 VAC
- Chassis Resistance measurements are made with a four-wire Kelvin bridge to eliminate errors due to cable length
- Test method complies with AAMI load per ANSI/AAMI ES1-1993
- Leakage Current can be measured in Open/Closed Neutral, Normal/Reversed Polarity and Open/Closed Ground
- All Leakage Current measurements are displayed directly in µAmps
