A BD representative diagnosed the problem as a faulty status board after we
observed the following:
Instrument status is normal (switches between not ready, standby and run modes)
Fluidics normal (sheath fluid pressurized, back flush and drain/fill work
fine, samples run fine)
laser is on (we physically checked)
but from the control page, we see wild fluctuations in the laser power (0.8
to 4.4 to 17 mW) and current (0.3 to 1.7 amps) and sample pressure (0.16
to 0.85 volts)
and a warning messages states that the SSC, FL1, FL2 PMT's are malfunctioning
Sound like we need a new status board?
Thanks!
