When the impedance test has been performed, a standard calibration can be performed by following the
procedure in section 3.7.1.
If the electrode traces for horizontal and vertical traces show drift, the traces can be manually centered using
the Center Traces button. If the patient’s eye movements are not shown in the electrode traces, then the
Amplifier Gain can be adjusted below the traces to magnify the patient’s electrode signals (
Figure 3.7-11).
