Portable megohmmeter 6555

for the aeronautical industry

The Megohmmeter Model 6555 is a high-end portable measuring instrument intended for the measurement of a wide variety 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 True Megohmmeter® Model 6555 is packaged in a rugged case that is IP65 when closed. Test results and configuration information are displayed on a graphical LCD screen and are exportable via DataView® (provided). This megohmmeter can operate on battery or AC power. 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. AC/DC Voltage Measurement Range - 1 to 4000V Accuracy - 1 to 99.9V: ±(1% R + 5ct) 100 to 4000V: ±(1% R + 1ct) Resolution - 1 to 99.9V: 0.1V 100 to 999V: 1V 1000 to 4000V: 2V Frequency Range - 1 to 2500V: DC or 15 to 500Hz 2501 to 4000V: DC Input Impedance - 3MΩ Insulation Measurement Test Voltage / Resistance Range - 500V: 10kΩ to 2TΩ 1000V: 10kΩ to 4TΩ 2500V: 10kΩ to 10TΩ 5000V: 10kΩ to 15TΩ 10,000V: 10kΩ to 25TΩ 15,000V: 10kΩ to 30TΩ
