4.3.1 Chest lead measurement
Please refer to the section 4.1 “Chest lead measurement” to connect the lead wires; enter “
” option setup menu to select “chest lead” for signal
input; return to default menu screen, move the cursor to the “
” measure icon, press the “
”ok key to enter into external electrodes measurement (3
lead wires) preparing screen, after 10 seconds, it will enter into the chest lead measuring screen, as shown in Figure 4-9. In this measuring mode, it
can measure and display the ECG signal of lead I, lead II, lead III or chest lead (V4) respectively according to electrodes placement.
4.3.2 Limb lead measurement
Please refer to the section 4.1 “Chest lead measurement” to connect the lead wires; enter “
” option
setup menu to select “limb lead” for signal input; return to default menu screen, move the cursor to the
“
” icon, press the “
”ok key to enter into external electrodes measurement (4 lead wires) preparing
screen. After 10 seconds, it will enter into the limd lead measuring screen, as shown in Figure 4-10.
