Action: Maintenance

Poly flow was 0.21, adjusted sheath flow knob until 0.31. This lowered sheath flow to 1.66 (2.42 on classifier). After attempting to correct this (with no success) we found the critical orifice was blocked. We cleaned it and found sheath flow had risen to 2.9. Adjusted excess and sheath flows until all were normal again
