LT544Dplus Digital Safety Tester

*NOTE: Effective June 27, 2014, this product is obsolete. The accessories for this product continue to be available for sale.
 LT544Dplus Digital Safety Tester
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: Line Voltage, Instrument Current, 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.
