Adjusting ISO, ST
These two points can be adjusted turning the knob.
When adjusting ST measurement point, the system will show the ST Measurement Point Window. The
QRS complex template displays in the window (If the template is not established, a horizontal line will
display. If the channel is not at ON position, a horizontal line will also display). It is adjustable of the
highlight bar in the window. You may select ISO or
ST,
then switch the knob left or right to move the
cursor line. When the cursor is at the required position, you may select the base point or the
measurement point.

Note : The alarm limits for two ST measurements are identical. No setting of alarm limits can be made
only for one channel.
Among physiological alarms, those belonging to the type that the parameter has exceeded the limits
may activate the recorder to automatically output the parameters and related measured waveforms
when the alarms occur on the condition that the alarm record switch in the related menu is On.
Tables below describe the possible physiological alarms, technical alarms and prompt messages
during ST measurement.
