Precision Measurements: The 1865 provides resistance measurement capability over a range of 1 kΩ to 100 TΩ (test voltage dependent), with a basic accuracy of 0.5%. 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, 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.

Easy To Use: The 1865's menu programming system, simple controls and indicators combine for efficiency of test and productivity. It's 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 instruments I/O interface give a clear indication of the measurement results.

Program 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 GPIB interface is also available (or added later) 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 that accommodates a variety of component types, including radial, axial, and chip components. Its shielded case reduces electrical noise and interference and includes a cover interlock switch and remote start for maximum operator safety.

Includes capacitor adapters, power cord, user manual, and calibration certificate. One-year warranty.
