4.8.2.1 Routine maintenance setting
[Routine maintenance] needs to manual maintenance by the user. The user can
set the routine maintenance time in [Routine maintenance settings]. When the
maintenance time is reached and the instrument is standby, the routine maintenance
process will be executed. The default time is 7:00 in the morning.
Basic operation
1) The analyzer performs whole machine reset. If there is an abnormality, an
error message is reported and the maintenance process is stopped;
2) Mix the reagent tray, turn on the peristaltic pump during the mixing process,
follow the cycle of running for 12s and stopping for 8s, and perform 2 cycles
every 1h of standby, calculate the number of cycles according to the regular
maintenance time set by the software;
3) The process about blocking test of aspiration probe is as follows:
◼ Three cuvettes loaded to the analyzer, grabbed to the cleaning tray from
the incubation tray, and turned to the three-phase injection probe injection
position. After added 500μL wash buffer, cuvettes will be taken off;
◼ The cleaning tray executes a cycle aspiration instruction;
◼ After the liquid aspiration is completed, the gripper grabs the cuvettes to
the incubation tray in turn, and turns the cuvettes to the sample position in
the outer ring of the incubation tray.
◼ The injection probe detects the liquid level of each cuvette in turn (only
data is recorded, no error is reported), and each cuvette is detected 3 times.
After the detection action is completed, the probe height data H1, H2, H3 of
each cuvette will be returned;Probe blocking judgment: The offset
parameter value of the sample/reagent probe at the bottom of the vertical
cup in the incubation tray is A, to determine whether the value meets
A-H1<120, A-H2 <120, A-H3 <120; If two of the three conditions are met,
which means the probe is unblocked, otherwise an error is reported, the
probe is blocked, the cuvettes will be tossed up once the detection is
completed.
Liquid injection and aspiration: the first cuvette corresponds to the first-phase
injection probe; the second cuvette corresponds to the second-phase injection
probe; the third cuvette corresponds to the third-phase injection probe. After
three-phase detection is completed, if any probe is blocked, the analyzer will
