Precision Measurements

   The 1865 provides resistance measurement capability from 1kΩ to 100TΩ (test voltage dependent) with a basic accuracy of 0.5%. To meet test requirements for a wide range of devices, the test voltage is fully programmable up to 21V DC. Sensing the proper resistance measurement range is done automatically, thus eliminating setup errors; and in order to eliminate lead or fixture errors, the operator can easily initiate an automatic zeroing routine of test leads.

Pass/Fail Testing

   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 provide a clear indication of the measured results.

Program and Data Storage

   Test setup conditions and measured results can be stored in instrument memory or on 3 1/2" disk when using the extended program storage option.

Automated Testing

   For automated system applications, the instrument includes an I/O interface connection with remote start and pass/fail outputs. An optional IEEE-488 interface is also available which enables the 1865 to be used under computer control.

Current Display Mode

   Besides a readout of insulation resistance in ohms, the operator can select a display mode for reading the measured current directly.

Safety Features

   The 1865 provides safety features such as current limiting, a warning indicator when high voltage is active, and safety interlock, all for protection of the operator.

Component Test Fixture

   An accessory fixture is available for use with the 1865 which accommodates a variety of component types, including radial, axial and chip components. It's shielded case reduces electrical noise and interference and includes a cover interlock switch and remote start for maximum operator safety.
