Adjust
The offset adjustment for ECG and respiration waveforms can be performed on this menu.
The offset adjustment function can be used when baseline position of the waveform is not
properly displayed even though the waveform position has been adjusted.
Reference For details of the waveform position adjustment, refer to the operation manual,
“6. Parameter Gain / Position Setup”.
CAUTION
Incorrect offset adjustment may cause failure of the equipment. As the
offset adjustment is performed at factory shipment, do not change the
setting unless it is necessary.
