Sensitivity
Probe sensitivity in microamperes depends on the sensitivity in microvolts of the
receiving equipment with which it is used. The following tables show the
relationship of receiving sensitivity in microvolts to the overall sensitivity of the
probe and receiver in microamperes. This data is based on the transfer
impedance of each model.
