Performance in the field… In a hard casing which is site-adapted for the most severe measuring conditions, the CA 6545, CA 6547 and CA 6549 megohmmeters offer the very best in insulation testing technology and accuracy. They measure voltages, frequencies, capacitance and residual current on installations or equipment. Their multiple functions not only qualify the measured insulation, but also provide real preventive maintenance. Site-proof casing with sealed (IP 53) shock resistant cover USB for connection to a PC or printing via a terminal (CA 6547 & CA 6549) Socket for AC mains connection and...

In-depth expertise… Main applications "THEORETICAL" REMINDER • Insulation measurement on cables, motors, generators, transformers, etc. 2 levels of diagnostics: • “Go/No go" measurement • Qualitative measurement for preventive maintenance: • Testing with programmed duration • Quality ratios: polarization index (PI) & dielectric absorption ratio (DAR) • Insulation testing on heterogeneous or multi-layer cables (dielectric discharge index (DD)) • Ramp by voltage steps • Locking of test voltages: ideal when entrusting the instrument to less experienced users • Measurement voltage selectable from...
