Troubleshooting and Maintenance
5.1 Troubleshooting
Code
Description Resolution
EC01
Cuff is too loose, maybe loose winding or
disconnected cuff
Retighten cuff or keep proper arm
position when inflation
EC02
Air leakage, maybe valve leakage or gas
path leakage
Tighten metal connector and check
the cuff. If leakage is not still
resolved, contact agent or dealer
EC03
Air pressure error, maybe unable to open of
valve
Check whether the valve can work
normally
EC04
weak signal,maybe week pulse or loose
cuff
Check whether the cuff is too loose,
tighten it if necessary.
EC05
beyond the limit,maybe the pressure of
subject beyond the limitation
Press “start/stop” button to measure
again. If not valid still, change the
monitor of larger rang
EC06
Excessive exercise,maybe there is too
much motion artifact or interference
Keep quiet when measured and do
not move the arm with cuff
EC07
overpressure,cuff pressure beyond
290mmHg in adult mode, 247mmHg in child
mode and 145mmHg in neonatal mode
Press “start/stop” button to measure
again.
EC08
Signal saturation,The amplitude of the
signal is too large due to activity or other
reason
Keep quiet, Press “start/stop” button
to measure again.
EC09
overtime:measuring time beyond 120s in
adult/child mode, 90s in neonatal mode.
Keep quiet, Press “start/stop” button
to measure again.
EC10 manual de-activation
Keep quiet, Press “start/stop” button
to measure again.
EC11 System error
Restart, If the error occur frequently,
professional Maintenance may be
necessary
EC16
Cuff pressure beyond the max pressure
setting
Reprogramming in PC software and
up-regulate the max inflation
pressure setting
EC32 The handshake communication fail
Press “start/stop” button to measure
again.
EC33
safe pressure beyond 15mmHg,
immeasurable
Gassing and remeasure when the
cuff pressure decline to below
15mmHg
EC34
Measurement finish ,and restart the
measuring when the pressure is still above
15mmHg
Gassing and remeasure when the
cuff pressure decline to below
15mmHg
EC35
No answer when the measurement
command is sent.
Press “start/stop” button to measure
again.
