3, Check the conductivity of the electrical conductor lead
is good
4, Check sample&reagent circuit board’s motor drive
circuit board kit part
Malfunction 2: When sample&reagent disc rotates to the
specified location, the sample&reagent disk does not stop
at the specified position, or when turns to specified
location, the photo sensor couldn’t detect it, or the signal
of the photo sensor is not correct
Solution:
Manually rotate the sample&reagent disk, transfer the
multimeter to DC, negative points P041, core plug No.6,
positive points P041, core plugs No.5
1, Multimeter readings between the positive changes in
5V and 0, indicates photo sensor and lead are normal
(1) Check lead
Check the conductivity of probe photo sensor J047 to
sample&reagent disk circuit board lead (P041) is good or
not, check both ends of connector is connected good or
not
(2) Check photo sensor’s electric circuit input of sample&
reagent disk’s circuit board
2, No change on multimeter reading
(1) Check wire
Check P041 plugs 4,5,6 core is connected well, a good
connection is connected at both ends
(2) Check the photo sensor signal
Check voltage between P041 pin plugs 4,6, if voltage is
not 5v, check the whether the connection plug is
connected well or not. If the voltage is 5v, check the J041
socket 5 feet of potential, raise up to the peak when the
potential is high, if not, the potential is low. If the
potential is not normal, check the photo sensor.
