C.A 6550 CHAUVIN ARNOUX

CHAUVIN ARNOUX C.A 6550 insulation resistance meter

FEATURES

• Robust housing with IP53 protection rating
  
• Electrical safety: 1000 V CAT IV - IEC 61010-1 and IEC 61557
  
• Large, monochrome, backlit, graphic LCD display (display: measurement results, text messages, bargraph, graphs)
  
• Built-in memory for 80,000 measurement results
  
• Measurement:
  

Insulation resistance from 10kOhm to 25TOhm with fixed test voltage thresholds: 500, 1000, 2500, 5000, 10000 V DC, or other user-settable test voltages in the range of 40 to 10000 V DC (with steps of 10 or 100 V DC)

Voltages (after test) from 1 to 2500 V AC and 1 to 4000 V DC

Capacitances in the ranges 0.009 ~ 9.999 ?F and 10.00 ~ 49.99 ?F

Leakage currents up to 8 mA

• Calculation of insulation quality factors: DAR, PI, DD, DR (ppm/V)
  
• Measurement function in step mode - up to 10 steps ( step test voltage and duration configurable by the user)
  
• Measurement function in rising test voltage mode (initial and final test voltage and test duration configurable)
  
• Insulation resistance measurement function with consideration of temperature and automatic calculation of measurement results with respect to reference temperature
  
• Operation mode with leakage current limitation configurable in the range of 0.2 ~ 5 mA
  
• Configurable test stopping moment to avoid insulation damage (setting the maximum rate of di/dt leakage current rise time)
  
• Measurement function with burning ("burning") - insulation testing regardless of leakage current value
  
• Possibility to observe the waveforms: R(t) + u(t), i(t), i(u) on the device display
  
• Improved display stability due to digital filtering function (3 filters with three possible time constants)
  
• Configurable alarms with overrun signaling by means of an audible signal and display indication
  
• Timer function; programming of test time
  
• High-voltage discharge function at the end of the measurement (protection against shock in installations with capacitive components)
  
• Communication interface - optically isolated USB and RS232 port
  
• Optional PC DataView software for connection to the device and advanced measurement analysis with reporting
  
• Power supply: 8 x 1.2 V (rechargeable NiMH battery), mains 90-260 V - 50/60 Hz (built-in charger)
  
• Dimensions: 340 mm x 300 mm x 200 mm
