3, Check whether the conductivity of the conductor’s lead
are good
4, Check the circuit board of the sample reagent disk
Malfunction 2: Sample reagent disk rotates, back
couldn’t find the position of back to zero
Solution: Manually rotate the sample&reagent disk,
transfer the multimeter to DC, negative points P041 core
plug No.3, positive points P041 core plug No.2
1. If multimeter reading is between positive 0 to 5V,
indicates that the photo sensor and the lead are normal
(1)Check the lead
Check the conductivity of probe photo sensor J047 to the
sample reagent disk’s circuit board lead (P041) is good or
not, check both ends of the connector are connected well
or not
(2)Check photo sensor’s electric circuit input of sample&
reagent disk
Check voltage between P041 pin plugs 1,3, if voltage is
not 5v, check whether the connection plug is connected
well or not. If the voltage is 5v, check the J041 socket 2
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 photo sensor.

barcode reader
Solution:
1, Check whether the barcode reader is well connected to
the instrument
2, Check whether the barcode reader is broken
Please reset the barcode reader, if it still doesn’t work,
check barcode reader. If it starts to work normally,
indicates that there is no problem on the barcode reader. It
might be the problem of digital wire or circuit board.

Solution:
1,Check whether there are friction between sample reagent
disk shelf and sample reagent refrigeration warehouse
2,Check whether sample&reagent disk fram has obstacles
that affect rotation
