Typical offset for clean electrodes is ≤ |30 V m
-1
| for the
parallel-plate configuration, which is reduced by the field
enhancement factor for typical inverted and elevated mounting
configurations.
2
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
-1
for the CS110 2 Meter
CM10 Tripod Site.

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.
Standard Mounting:
2 m height on a CM10 tripod mast
Site Correction:
Site correction factors available for several standard
mounting configurations
