8.1 Lead Fault
1. Data saturation or overflow happens.
Solution:
Ensure that all leads are in good contact, and wait for half a minute or the waveforms on the screen are stable,
and then start printing.
2. Straight line is printed in some leads.
Solution:
1) Check if the metal piece of electrode contacts the animal body properly; if not, adjust the position of the
electrode, and adjust the tightness if necessary.
2) Check if the electrodes are oxidized or faded, and clean the accessories or replace with new ones.
Oxidation and aging cause conductive deterioration of the electrode sheet, resulting in poor signal
transmission.
3) Treat the skin of the animal with alcohol; especially in the winter of the North, dry skin causes skin
resistance to become larger, which will impact the signal reception.
4) Please clean the joints of lead wires and electrode holders, reinstall and tighten all joints. After
long-term use, the joints will have dirt or become loose, resulting in poor signal transmission.
5) Check if the appearance of the lead wires has obvious fracture; if yes, replace with new lead wire. If not,
connect a proper lead wire to the device. If the waveform is stable, the lead wires have problem and
have to be replaced.
6) If there is no lead wire available, check if the lead wires conduct with a multimeter. First check if the
inner conductors of the lead wires are conductive. Generally speaking, the acceptable resistance shall be
about 10 kΩ. Then check if there is a short circuit between the outer shield and inner conductor. The
resistance shall be infinity. If the lead wires have a problem, please contact our service department to
replace new lead wires.
3. The other reason for lead fault can be caused by failure in signal communication. Please exclude other causes
for lead fault problems first, and contact our service technicians if necessary.
