The Chauvin C.A 6549 megohmmeter is a top-of-line measuring instrument, portable, in a rugged construction-site housing with cover, with a graphic screen, operating from battery or line power.

The C.A 6549 has an internal memory for storing several thousand measurements. Storage is performed with two indices, OBJ (object) and TEST (test), which store the results in an ordered way.


The resistance of a faulty insulant gradually decreases as the test voltage rises. This test, which involves increasing the test voltage in steps, can be used to assess the quality of the insulant by observing the curve R(Utest) and the result in ppm/V which provides a quantitative evaluation of the curve's slope.


The value of an insulation resistance varies according to the measurement temperature. For accurate, reliable monitoring, it is always a good idea to express a measurement result in terms of a reference temperature. By simply pressing a button, the calculation can be performed automatically by the instrument.


Measurement range: 10 kΩ to 10 TΩ.
4 fixed test voltages.
Adjustable test voltage position: 40 to 5,100 V in 10 V or 100 V increments.
Large backlit LCD screen with digital display and bargraph.
Quantitative insulation analysis: DAR, PI and DD (dielectric discharge) quality ratios calculated automatically and R(t) stored.
Large number of functions: programmable test duration, test voltage locking, smooth function, programmable alarms, etc.
Power supply: NiMH rechargeable battery for 30 days' operation with 10 DAR measurements and 5 PI measurements per day.
