Instruction Manual
CS110 electric field measurement instrument gain is a function of electrode
dimensions, along with the 1% feedback capacitor used in the charge amplifier.
While measurement drift of CR1000 is likely negligible with regard to the
±
5% of
reading accuracy specification of electric field measurements, datalogger drift may
be a factor for the measurement of temperature by means of an external
temperature and RH probe.
A parallel-plate calibration is recommended whenever any electrodes are bent,
removed or replaced, with the exception of the removal and replacement of the
same stator during the process of insulator cleaning. For CS110 applications
requiring long-term electric field measurement accuracy better than ± 10%, a
parallel plate factory calibration is recommended every three years.
The expected lifetime of the CS110 is 5 to 10 years, again depending upon the
operational environment. Instruments operated in coastal environments will likely
suffer from external finish degradation and/or operational failure sooner than
instruments operated in dry inland environments.
