In order to avoid misinterpretation of ERG recordings taken with canthiskin electrodes, the potential deriving from the two electrodes was fed into a balancing amplifier that eliminated opposing voltages and amplified unidirectional voltages. During voluntary as well as nystagmus caused eye movements as well as those caused by nystagmus clearly distinguishable averaged ERG's were recorded.
为避免对用睑裂皮肤电极记录的视网膜电图（ERG）产生误解，将来自两个电极的电位输入平衡放大器，该放大器消除反向电压并放大单向电压。在自愿性眼动以及眼球震颤引起的眼动过程中，均记录到了清晰可辨的平均ERG。
