DESCRIPTION
The MFM 10-1’s intuitive menu-driven operation and bi-polar function ensures that external thermoelectric
automatic measurement and evaluation system enables and galvanic influences are eliminated. A multi-section
cable sheaths to be tested and sheath faults to be pre- facility permits the entry of cable segments with different
located and pinpointed as simply as possible. Data is parameters. Difficult cable faults can be “burned” thanks to
entered using the proven Megger rotary encoder principle the available high current of up to 750 mA.
and is supported by a touch screen.
MFM 10-1 can also use its integrated protocolling feature
The very powerful 10 kV DC source with positive and with the approved MeggerBook RE software to easily
negative polarity allows HV cables to be tested. The generate test reports.
