1865 Megohmmeter of IET Labs

IET is particularly pleased to add the 1865 because it boasts important unique features and performance not found elsewhere:

  • Program and Internal Data Storage, with RS-232 and IEEE-488 Interface
  • Precision Measurements from 1 kΩhm to 100 TΩhm with basic accuracy of 0.5% from 1-1000 VDC with averaging for Increased Accuracy
  • Direct Reading of Measured Resistance or Current
  • Large LCD Display for Menu Programming of Test Results
  • Fully Programmable Measured Cycle Times
  • Approved for Boeing Aircraft
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 TOhms 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.

Precision Measurements: The 1865 provides resistance measurement capability from 1kΩhm to 100TΩhm (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.

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.
