The AEMC Model 6555 Megohmmeter is a high-end portable measuring instrument intended for the measurement of a wide varity of electrical insulation resistance values on cables and devices operating at high voltage. It is the only fully automated 15,000V graphical insulation tester. The Model 6550 is packaged in a rugged case that is IP54 when closed. Test results and configuration information is provided on a graphical LCD screen as well as exportable through the use of DataView® software provided. This megohmmeter can operate on battery or AC power while testing.

The Model 6555 also offers the ability to program up to three step voltage profiles (from 40 to 15,000V), each containing up to ten steps. There are also three ramp profiles and three programmable test voltages in addition to the standard fixed voltages of 500, 1000, 2500, 5000, 10,000 and 15,000V.

Features:

• Detection and measurement of input voltage, frequency, and current prior to running a test
• Measurements at a fixed test voltage of 500, 1000, 2500, 5000, 10,000 or 15,000VDC
• Measurements at an adjustable test voltage between 40 and 15,000VDC
• Ramp voltage measurements with a ramp from 40 to 1100V or from 500 to 15,000V
• Step voltage measurements with steps from 40 to 15,000V
• Non-destructive (Early break) test, test stopped at a preset current (Break at I-limit) or Burn mode with no predefined stop point
• Digital filtering of insulation measurements
• Live measurement of the voltage to warn the operator of potential unsafe conditions
• Programmable thresholds to trigger audible
• Timed measurement duration checks
• Fuse protection with display indication of defective fuse condition
• Stores up to 80,000 measurements
• Optically-isolated USB communication for transfer onto PC and and report generation with the included DataView® software
