To meet the test requirements for a wide range of devices, the test voltage is fully programmable up to 1000 Vdc. Sensing the proper resistance measurement range is done automatically, eliminating setup errors. The operator can initiate an automatic test leads zeroing routine in order to eliminate lead or fi xture errors. Easy to use: The 1865’s menu programming system, simple controls and indicators combine for ef fi ciency of test and productivity. Its multi-function keypad provides the operator with an easy way to program and make measurements. Pass/Fail: Measured results are automatically compared to an operator-programmed limit for pass/fail testing. Pass/Fail indicator lights or a pass/fail output from the instrument's I/O interface give a clear indication of the measurement results. Program data storage: Test setup conditions and measured results can be stored in CSV format for easy use with Microsoft Excel. Storage options include:
  • 512 MB of internal instrument memory,
  • A computer (via the IEEE interface)
  • A fl ash drive (via the USB port) New programs can also be uploaded via the IEEE interface or the USB port. IEEE Interface (7000-23): IEEE to RS-232 Adapter Rear Panel Input (1865-03): Rear input is available as an alternative to front input. This option places the banana jacks on the rear panel. Rack Mount Kit (1865-50): This kit allows the 1865 unit to be installed in a standard 19" rack mount fi xture. Shielded Lead Set (1865-51): This set is available to reduce external noise during the calibration. Component Test Fixture (1865-52): An accessory fi xture which accommodates a variety of component types, including radial, axial, and chip components. Its

DESCRIPTION

Automated testing: For automated system applications, the 1865+ includes an I/O interface connection with remote start and pass/fail outputs. An optional IEEE-488 interface is also available (or can be added later), which enables the 1865 to be remotely controlled by a computer. Display mode (Resistance or Current): The operator may select display mode to read either measured resistance or measured current. Safety features For protection of the operator, the 1865+ provides safety features such as current limiting, a safety interlock, and a warning indicator when high voltage is active. shielded case reduces electrical noise and interference and includes a cover interlock switch and remote start for maximum operator safety.
