The benchmark for 50 V to 1 kV insulation measurement Giant back-lit LCD screen with digital display + bar graph 2 kΩ…4 TΩ range Automatic calculation of insulation quality ratios (DAR, PI) Graph plotting R(t) Memory / RS232 / rechargeable battery (C.A 6543)

Instruments built for on-site use! n their compact hard cases, megohmmeters C.A 6541 and C.A 6543 give you the very best in insulation testing technology. These microprocessor-controlled instruments are equipped with highly advanced functions for measurement of insulation (up to 4 TΩ at 50 V to 1000 V), AC/DC voltage, continuity at 200 mA, resistance, capacitance... Model C.A 6543 also comes with a rechargeable battery, memory and an RS232 serial link, enabling you to control the instrument with a PC. This also makes it possible to transfer data from memory for processing via the specially developed...

Expert insulation analysis at 50 V to 1 kV! POLARISATION INDEX (PI) AND DIELECTRIC ABSORPTION RATIO (DAR) Insulation test results on rotating machines can be rendered inaccurate due to transient eddy currents that interfere with the measurement before they cancel out. To eliminate their influence on the test it is necessary to measure over a long duration. The absolute insulation value, read off at the end of the measurement, and the calculation of PI and DAR coefficients (automatic on the C.A 6541 and 6543) go to make it possible to qualify the quality and ageing of insulation. Insulation quality...
