The laser
current is
abnormal
Abnormal laser
current.
Refer to 2.4.1 Integral Replacement of the Optical
Assembly to disassemble the optical shield cover and
see if the optical laser is on with normal power input (the
normal measurement range of the optical power meter is
4.8+/-0.5). If the optical laser is not on or the measured
optical power is far lower than 4.8, this means that the
laser is burnt out. Please refer to
2.4.1 Integral
Replacement of the Optical Assembly to replace the
entire optical assembly.

The 12V
power is not
working
properly
+12V power is not
working properly. Refer to 3.9 Main Control Panel Replacement to
replace the main control panel.
-12V power is not
working properly.
7
Abnormal
background
voltage
Abnormal HGB
background voltage.
(The rated range of
background voltage is
4.2~4.8V; a system
message "abnormal
background voltage"
will be shown to
remind the user to
adjust HGB gain.)
1. Take another measurement after performing the
soaking with probe cleanser to see if the problem has
been resolved. If not, enter into the system for multiple
times to check HGB background voltage. If the voltage
is steady and exceeds the standard ratings, please
perform the following procedures.
2. Go to Setup > Host Settings > Gain Settings screen,
adjust the current HGB gain and set HGB background
voltage within 4.5+/-0.1V.
3. If the problem persists, please try to clean the
transmitting end and the receiving end of the HGB
bracket. These two areas should not be cleaned with
alcohol or organic solvents. Instead, use a rubber
pipette bulb for purging. If the counting bath is
contaminated with liquid, wipe it clean with lint free
tissue.
4. If the problem persists after the above steps are taken,
please consider replacing any relevant components
such as the HGB bracket or analog panel.
8
Abnormal
temperature
The ambient
temperature exceeds
the working range.
Check if the ambient temperature is within the specified
range of 15~30°C; if yes, refer to
3.11 Disassembling
and Replacing the Temperature Sensor to replace the
temperature sensor.
Preheating bath
temperature out of
working range Check if the wiring between the temperature sensor and
the heating plate in DIFF bath is loose. If the connection
is OK, replace the DIFF bath.
Optical system
temperature out of
working range.
Check if the wiring between the optical temperature
sensor and the heating rod in the DIFF bath is loose; If
the connection is OK, use a thermometer to measure the
temperature inside the aperture at the top of the
front-end optical assembly. Check if the temperature is
within the working range.
If it is not, replace the heating rod; otherwise, replace the
temperature sensor.
