Solution: Manually make the probe body go up to the
peak repeatedly, transfer the multimeter to DC, negative
points the first 6-core plugs P042, P042 positive pole core
plugs 5.
1, multimeter readings between the positive changes from
5V to 0, indicating photo sensor and lead are normal
(1) Check conductors
Check whether the sample probe’s photo sensor J202 to
the reagent disc circuit board (P042) is in good
connection, and whether the both ends of the connectors
are good.
(2) Check the input of the sample reagent disc circuit
board’s photo sensor.
2, No change on multimeter reading
(1) Check conductors
Check P042 plugs 4,5,6 core is connected well,
connection of both ends is good.
(2) Check the photo sensor
Check voltage between P042 pin plugs 4,6, if the voltage
is not 5v, check the connection plug is connected well. If
the voltage is 5v, check the J042 socket 11 feet’s potential.
Rising to the peak when the potential is high, if not, the
potential is low. If the potential is not normal, check the
photo sensor.

Reagent probe
abnormal.
Probe senses
the liquid
touches the
side
touching the side of the reagent cup or the botom of the
cup
Solution:
Observe the Sample&reagent probe’s running status
(1) If the Sample&reagent probe is touching the side of
the cup while it’s running, need to ajust the position of the
Sample&reagent probe’s and the position of the cup
(2)If the probe directly touches the botom of the cup while
it’s running, check whether there is reagent in the reagent
cup. If not, need to add reagent and then check. If yes,
need to check the circuit board of the liquid surface, check
whether the sensitivity of the Sample&reagent probe is
working normally.

Reagent probe
abnormal.
Sample&reage

descending
system, execute "reset". Observe probe running status
Malfunction 1: The arm of the probe couldn’t move
Solution: 1 Manually move the probe mechanism, need
mechanical repair if resistance is big
2, check whether the motor connector body is connected at
both ends in a good well function way
3, check whether the connection of electrical conductor is
