Installation Method Of ECG Paper
ECG roll paper is easy to operate. Like roll paper, take down the old one, replace it with a new one, and install it when the direction is right. The storage ECG paper needs to be unpacked first, with good direction. Generally, there are arrow marks up and down. If there is no arrow, look at both ends. If there is red, it is the bottom. If there is no arrow, it is the top. Or look at the black sensing point, usually at the bottom. Pull the bottom a little out and close the hatch so that it can be installed.
