Wide resistance measurement range: 0.1 to 510 milliΩ High performance AC current output: 3 to 45 Amps Compact size ground bond tester Provide reliable and stable test results Built-in resistance compensation function Functionally identical to Chroma 19572 Ground Bond TesterWide Test Current Range: User programmable output current, 3A to 30A AC in 0.01A steps, provides extensive coverage for testing to UL, CSA, VDE, IEC and other agency safety requirements. Programmable Source Voltage: Limit the voltage to the DUT using the programmable source voltage from 1.0V to 8.0V rms and meet the low voltage requirement of CSA 22.2 No. 0.4 Bonding and Grounding of Electrical Equipment (4V, 30A, 100mΩ limit, 2-minute test) plus many others. Programmable High and Low Resistance Limits: A resistance measurement range from 0.1mΩ to 510mΩ plus user programmable high and low resistance limits with Pass/Fail indication make this tester ideal for production Go/NoGo testing. Remote Control: Incorporate the Sentry 50 Plus unit into an automated manufacturing environment with remote start and Go/NoGo results output through the rear panel PLC interface. Hipot Compatibility: The Sentry 50 Plus can be used alone or connected to the Sentry Plus 10, 20 or 30 Hipot Testers for complete product electrical safety testing with the push of one button. When the Sentry 50 Plus has completed a continuity test, with pass indication, it can remotely start the Sentry Plus Series instrument for a hipot test in sequence. Built-in Calibration via Software: Front panel display of an operator prompted calibration routine makes for no internal adjustments.
