The QuadTech Medical Device Safety Analyzers, available in two convenient models: the portable 277 and the bench top 299, provide an integrated safety testing solution for medical device testing in R&D, Manufacturing and Service environments. Both are advanced microprocessor controlled units for testing Class I and Class II equipment in accordance with requirements outlined in IEC60601, EN60601, NFPA99, ANSI/AAMI, MDA, DB9801 and VDE0751. The 277 and 299 automatically load tests required for compliance; the units can also be controlled manually.

Earth Bond Test: Verifies earth continuity between exposed metal parts of the test device and power line ground, or between two probed points. Test currents of 0.1, 1, 10 or 25A can be applied and resistance measured over a range from 0 to 20 ohms.

Insulation Resistance Measurements: Verifies that mains power lines are adequately insulated from earth ground and from applied parts. 350 or 500V DC can be applied and insulation resistance up to 100Mohms is measured.

Earth and Enclosure Leakage: Measures earth and enclosure leakage current under normal, reverse, or single fault test conditions using IEC60601 or ANSI body models.

Patient Leakage: With up to 11 possible connections, the tester measures patient leakage current through applied parts or applied parts to ground, individually or connected together. All tests are automatically performed in sequence under normal, reverse, or single fault test conditions.

Patient Auxiliary Leakage: Measures and displays leakage current between any two applied parts or between any applied part and all others connected together. Measurements are also performed under the required mains power conditions.

Patient Leakage F-Type: Measures and displays the current that would flow from a patient via an F-Type Applied Part to ground if the patient were at mains potential.

Load Test: Measures the power consumption of the device under test and displays the result in kVA. Also measures and displays the power line voltage.

Three Operating Modes: Fully automated sequence testing, semi-automated sequence testing with provisions for operator intervention and changing of probe connections, or manual control of each individual test.

Output Results: All test results can be output to the built-in printer of the Model 277or external printer with the Model 299. For remote control operation or data-logging, both models include an RS-232 interface standard.
