QuadTech 1865

Quadtech IET 1865 Migohmmeter / IR Tester.

The 1865 Megohmmeter/IR tester, with digital display, is used for high accuracy measurements of insulation resistance on a wide variety of components, materials and electronic devices. Resistance values greater than 100 teraohms can be measured with a basic accuracy of 0.5% at DC voltages up to 1000V. A programmable limit makes the unit ideal for pass/fail testing in a production environment and is also adaptable for use in automated system applications with its optional IEEE-488 interface.

Description

Precision Measurements: The 1865 provides resistance measurement capability over a range of 1kΩ to 100TΩ (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 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.
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. Psss/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 1865 includes an I/O interface connection with remote start and pass/fail outputs. An optional IEEE-488 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 which accomodates 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.
