The Chauvin Arnoux 5000 V digital insulation tester, in its site-proof case, the C.A 6545 megohmmeter can be used for quantitative and qualitative analysis of insulation. It also automatically measures voltage, capacitance and residual current.

Measurement range is 10 kΩ to 10 TΩ
4 fixed test voltages are 500 / 1000 / 2500 and 5000 V
Adjustable test voltage positions of 40 to 5,100 V in 10 V or 100 V increments
Large backlit LCD screen with digital display and bargraph
Quantitative insulation analysis of DAR, PI and DD (dielectric discharge) quality ratios calculated automatically and R(t) stored
Large number of functions like programmable test duration, test voltage locking, smooth function, programmable alarms, etc.
Power supply is NiMH rechargeable battery for 30 days' operation with 10 DAR measurements and 5 PI measurements per day
Electrical safety i.e.. IEC 61010-1 Cat.III 1000V or Cat.I 2500V and IEC 61557
