1
Typical offset for clean electrodes is ≤ |30 V/m| for the parallel-plate configuration, which is reduced by the field
enhancement factor for typical inverted and elevated mounting configurations.
2
The CS110 incorporates automatic gain ranging between two input ranges. The measurement is first tried on the
lowest input range. If the signal is too large for the lowest range, the larger range is used.
3
Field enhancement due to typical inverted and elevated mounting requires additional site correction, estimated at
±5% accuracy when done in appropriate high field conditions. Practical outdoor CS110 electric field measurement
accuracy is estimated at ±5% of reading + 8 V/m for the CS110 2-meter Tripod Site.
