  • Description

    C.A. 6545 5kV Megohmmeter

    The C.A. 6545 5kV Megohmmeter offers the very best in insulation testing technology & accuracy and can be used for both quantitative and qualitative analysis of insulation. The C.A. 6545 Megohmmeter measures voltage, frequency, capacitance and residual current on installations or equipment. The CA 6545 is capable of measuring insulation up to 10 Tera ohms at a test voltage of up to 5000V DC.

    The 6545 mega ohmmeter can automatically calculate the polarisation index (PI) and dielectric absorption ratio (DAR) which can be used to qualify the quality and ageing of insulation. In addition this insulation tester can measure and calculate the dielectric discharge index (DD). To measure as accurately as possible the test voltage can be adjusted between 40 and 1000V in 10V steps and between 1000 and 5100V in 100V steps. The CA6545 HV insulation tester also provides time-controlled testing, programmable alarms and a SMOOTH function.

    C.A. 6545 5kV Megohmmeter Features:

    • Wide range from 30kΩ to 10TΩ
    • 4 fixed test voltages: 500/1,000/2,500 and 5,000V
    • Programmable test voltage position in increments of 10V or 100V
    • Large backlit LCD screen with bargraph
    • Qualitative analysis: automatic calculation of DAR, PI, DD ratios & tracing of the R(t) curve
    • Programmed test duration, lock-in of test voltage, smooth function & programmable alarms.
    • Rechargeable battery with a 30-day service life for 10 DAR & 5 PI measurements per day.
    • Site-proof casing with sealed IP53 shock resistant cover
