1865+ Megohmmeter/IR Tester - 1

1865+ Megohmmeter/IR Tester A Megohmmeter/IR Tester with digital display used for high-accuracy measurements of high resistance and insulation resistance. It includes a programmable limit for pass/fail testi ng, USB host port, and RS-232 interface. General Features • Proven over many years in the field • Measurement range up to 100 TO • 0.5% measurement accuracy • High-visibility blue LCD graphical display • Automatic ranging • Automatic zeroing of test leads • Direct reading of Insulation Resistance • RS-232, I/O port, and USB interfaces • Optional IEEE-488 to RS-232 Adapter • Programmable test voltage from 1 to 1000 Vdc • Programmable test times • 512 MB of internal storage of test-setup and results • CSV file format for easy use with Microsoft Excel • Limit entry for Pass/Fail testing • Keypad lockout with password protection DESCRIPTION Precision measurements: The 1 865+ provides resistance measurement capability over a range of 1 kO to 100 TO (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, eliminating setup errors. The operator can initiate an automatic test leads zeroing routine in order to eliminate lead or fixture errors. Easy to use: The 1865's menu programming system, 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: 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 give a clear indication of the measurement results. Program data storage: Test setup conditions and measured results 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+ 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. Display mode (Resistance or Current): The operator may select display mode to read either measured resistance or measured current. Safety features For protection of the operator, the 1 865+ provides safety features such as current limiting, a safety interlock, and a warning indicator when high voltage is active. OPTIONAL ACCESSORIES IEEE Interface (7000-23): IEEE to RS-232 Adapter Rear Panel Input (1865-03): Rear input is available as an alternative to front input. This option places the banana jacks on the rear panel. Rack Mount Kit (1865-50): This kit allows the 1865 unit to be installed in a standard 19" rack mount fixture. Shielded Lead Set (1865-51): This set is available to reduce external noise during the calibration. shielded case reduces electrical noise and interference and includes a cover interlock switch and remote start for maximum operator safety. IET LABS, INC Component Test Fixture (1865-52): An accessory fixture which accommodates a variety of component types, including radial, axial, and chip components. Its
