The power-up table, Table 2.1-3, is run by the instrument during its power-up process.
Table 2.1-3 Power-Up Cycle
Time
(seconds) Activity Requested
0.0 Drain WBC bath. Rinse and drain 3 times consecutively. This uses about 16 mL of diluent from reservoir.
14.0 Check diluent sensor. It should not see diluent and displays
ERROR DETECTED (017) Unable to Sense
Diluent Level
if it does. Drain VIC and fill diluent reservoir to sensor.
80.0 Continue filling diluent reservoir if it is not filled to sensor.
80.0 Overfill diluent reservoir and check diluent sensor. Display
ERROR DETECTED (017) Unable to Sense
Diluent Level
if no diluent is sensed. Turn on vacuum pump and drain RBC bath.
85.0 Drain probe wipe line and prefill WBC bath from diluent syringe while draining.
90.0 Request that a probe warning be displayed, and charge diluent syringe to 3.7 mL.
93.0 Force 2.5 mL of diluent through probe wipe.
97.0 Move aspirate probe up while wiping with 1.2 mL of diluent.
99.0 Move aspirate probe to aspirate position while rinsing RBC bath.
101.0 Move aspirate probe to WBC position while filling aspirate syringe.
102.0 Move aspirate probe to RBC position, then down, then up, then drain VIC. This verifies that all Probe/Wipe
Traverse Assembly position sensors are working.
107.0 Move aspirate probe down, home aspirate syringe, move aspirate probe up.
115.0 Fill diluent syringe with 4 mL of diluent and aspirate syringe with 50
µ
L of diluent while draining RBC bath.
118.0 Wash aspirate probe as it moves down, dispense 50
µ
L of diluent from aspirate syringe, drain RBC bath.
123.0 Move aspirate probe up, charge diluent syringe to 4 mL, fill diluent reservoir.
128.0 Drain WBC bath while prefilling with 2 mL of diluent, then drain RBC bath while prefilling with 1 mL of
diluent. This primes prefill tubing.
132.0 Fill diluent syringe with 1.2 mL of diluent while moving probe down. Wash aspirate probe as it moves up,
while also draining WBC bath.
136.0 Drain VIC, apply mixing bubbles while rinsing WBC bath, drain WBC bath.
140.0 Fill diluent reservoir, then rinse RBC bath while applying mixing bubbles. Drain RBC bath and fill diluent
reservoir.
145.0 Rinse WBC bath, fill diluent reservoir, rinse RBC bath, fill diluent reservoir.
156.0 Open up aperture count and sweep-flow lines. Prime for 25 seconds.
181.0 Close RBC aperture count and sweep-flow lines. Continue priming WBC aperture module for 25 seconds
206.0 Drain VIC, turn off vacuum pump and fill diluent reservoir.
211.0 Drain WBC bath.
213.0 Rinse WBC bath, drain RBC bath, then fill diluent reservoir.
217.0 Zap apertures for 1 second and fill diluent reservoir.
228.0 Power-up cycle is complete.
