QuadTech Inc, Digital Megohmmeter/IR Tester ( 1865 )

Description

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 1000V 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 accomodates 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.
