Please enter the “practice mode” first, and confirm the waveform with a finger test. Video / Picture
*It is recommended to take the video and signal during the test, so that we can quickly understand the problem when needed.
If the signal tested by the finger is OK, it means the device is OK;
If you cannot see a clear QRS waveform, please try to place the device as close as possible to the mobile phone/tablet, and away from metals, power supplies, electrical appliances, air conditioners and other objects, and then retest. If you continue to be unable to see a clear QRS waveform, there may be a problem with the device.
If you have confirmed that there is no problem with the device, but you cannot get clear waveforms when you clamp the animal, please clamp yourself with the electric cable and test it; if there is a problem with the signal, it may be a problem with the electric cable!
