Leakage current on output of IZ2 in Current mode.

Tech Note: TN0894
Product: IZ2, IZ2H
Version: IZ2 SN < 3000, IZ2H SN < 2000
Date Added: 2011-12-06


In current mode, there may be a leakage current on the output of the stimulator. This DC offset depends on the temperature.

This issue has been addressed in new IZ2s. A fan has been added to the unit for better cooling and resistor changes in the output stage reduce the effectiveness of the offset error. An ACC16-Z coupler is also available to eliminate the offset.
