TECHNICAL INFO

6555 10,000V/15,000V Megohmmeters
The Megohmmeter Model 6555 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 6555 is packaged in a rugged case that is IP65 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.
