C.A 6421
Measure the earth!
Autonomous and waterproof, the C.A 6421 is a light site instrument, easy to use, designed for use in the field. Earth resistance is measured on a large, very sturdy galvanometer using traditional rod methods.
earth resistance: 0.5Ω at 1000 Ω (log scale)
3 fault presence indicators to validate the measurement
measurement frequency: 128Hz
connection of rods to colour-coded terminals
captive connection strip removable between S and H for measurement of 2-wire resistances
protection by HPC fuse
power supply: 8 x 1.5V batteries for average charge life of 1,800 15-sec measurements (continuous control of battery charge)
measurements in compliance with IEC 61557, VDE 0413 and BS 7671
