The 1865 + is the Megohmmeter for todays most challenging applications

New Significantly Improved Version of a trusted standard.

Unit comes with optional CE marking which is a mandatory conformance mark for products being used in Europe

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 megohmmeter ideal for pass/fail testing in a production environment and is also adaptable for use in automated system applications with its included RS-232 Interface or optional IEEE-488 interface.

Precision Measurements: The IET Labs 1865 + Megohmmeter 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.

Easy to use: The 1865+'s menu programming system is significantly improved, simple controls and indicators combine for efficiency of test and productivity. Its multi-function keypad provides the operator with an easy way to program and make measurements.

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 megohmmeter I/O interface provide a clear indication of the measured results.

Program and Data Storage: Test setup conditions and measured results of the megohmmeter 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 flash drive (via the USB port)

*New programs can also be uploaded via the IEEE interface or the USB port.

Automated Testing: For automated system applications, the 1865+ Megohmmeter 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.

Resistance or 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 + Megohmmeter 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+ Megohmmeter which 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.
