HCI
High Current Interrupt measurements (HCI), optionally available forall ZENNIUM modular electrochemical workstations, boosts the high frequency performance for dynamic system analysis by a factor of three to ten.
It consists of a TR8M transient recorder and a calibrated pulse probe. An external device from the PP-Series or EL-Series is needed in addition.
Even at the end , when mutual induction finally limits the EIS at higher frequencies, ZAHNER can offer a solution:
High Current Interrupt measurements (HCI), optionally available for the IM6 systems, boosts the high frequency performance for dynamic system analysis by a factor of three to ten. HCI complements EIS measurements at very low impedances in the higher frequency range, what is of high interest for accurate determination of ohmic losses and self inductance of power devices. A TR8M transient recorder plug-in and an EL type electronic load, together with a pulse probe is needed to extend the IM6 or ZENNIUM for this application.
