This setting determines when the cardiograph will switch off in order to conserve the battery life of the unit. The
battery timeout will only occur if the keypad has not been depressed for the time specified. This setting will be
ignored while the unit is transmitting, rhythm printing or detects an ECG input signal.
AC Filter
The ELI 210 removes 60Hz or 50Hz interference. The setting you select depends on the line frequency in your
country. Always use the 60Hz setting in the United States. If the AC interference is present, check to see that the
proper AC filter is selected.
Paper Speed
The writer speed can be configured at 25mm/s or 50mm/s for default ECG printouts. For rhythm printouts and
display, speeds of 5mm/s or 10mm/s are also available. See Section 4 to change speeds for display or rhythm
printing.
Filter
The ECG plot frequency filter (or print filter) can be set to 40Hz, 150Hz, or 300Hz. The plot frequency filter does
not filter the acquired digital record. A 40Hz plot filter setting will reduce the noise (40Hz and higher frequencies)
on the printed ECG, a 150Hz plot filter setting will reduce the noise (150Hz and higher frequencies) on the printout
and a 300Hz plot filter setting will not filter the printed ECG.
Height/Weight Units
This option defines the units of weight and height to either pounds/inches (lb/in) or kilograms/centimeters (kg/cm).
