Appendix E. CS110 as a Slow Antenna
E-6
E.4 Calibration
The factory calibration described in Section 5 applies to the maximum amplitude
of the step response of the CS110 when it is operating as a slow antenna.
Switching in the 200 M
Ω
resistor in the feedback path simply slows the decay of
the signal induced on the sense electrode resulting in a 66 millisecond decay time
constant
The CS110 operating as a slow antenna returns the change in the electric field
with units of volts per metre per scan. A 50 Hz scan interval would yield:
X volts * metre
-1
* 20 ms
