The AEMC 6555 Portable Digital Megohmmeter is a fully automated 15,000V graphical insulation tester. Features the ability to set up three step voltage profiles (40V to 15,000V), each including up to ten steps. Also includes three ramp profiles and three programmable test voltages in addition to the default set voltages of 500V, 1000V, 2500V, 5000V, 10,000V, and 15,000V. Fully compatible with PC.
- 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
