AMIN = The minimum allowed volume delivered from a calibrated acid pump based upon the
current machine settings. This value is used in the preventative maintenance procedure.
AMAX = The maximum allowed volume delivered from a calibrated acid pump based upon the
current machine settings. This value is used in the preventative maintenance procedure.
BMIN = The minimum allowed volume delivered from a calibrated bicarbonate pump based
upon the current machine settings. This value is used in the preventative maintenance
procedure.
BMAX = The maximum allowed volume delivered from a calibrated bicarbonate pump based
upon the current machine settings. This value is used in the preventative maintenance
procedure.
A160 = Stroke volume of the acid pump at 160 steps per stroke. This volume was determined
and put into battery RAM during acid pump calibrations.
(For example: 8620 = 0.8620 ml/stroke).
B160 = Stroke volume of the bicarb pump at 160 steps per stroke. This volume was determined
and put into battery RAM during bicarb pump calibrations.
(For example: 8620 = 0.8620 ml/stroke).
A220 = Stroke volume of the acid pump at 220 steps per stroke. This volume was determined
and put into battery RAM during acid pump calibrations.
(For example: 8620 = 0.8620 ml/stroke).
B220 = Stroke volume of the bicarb pump at 220 steps per stroke. This volume was determined
and put into battery RAM during bicarb pump calibrations.
(For example: 8620 = 0.8620 ml / stroke).
APV = Current acid pump stroke volume based on ACID.
(For example: 8620 = 0.8620 ml / stroke).
BPV = Current bicarb pump stroke volume based on BIC.
(For example: 8620 = 0.8620 ml / stroke).
CTCD = Calculated theoretical conductivity based on Na+, bicarbonate, and concentrate selected.
NaRT = Remaining time in a sodium variation program (SVS). This value will be 0:00 if no
program is running.
HI ART = Hardware high arterial alarm (actuator).
AART = Calculated arterial pressure by the actuator board to within 1 mmHg.
LO ART = Hardware low arterial alarm (actuator).
AVEN = Calculated venous pressure by the actuator board to within 1 mmHg.
HI VEN = Hardware high venous alarm (actuator).
ATMP = Calculated TMP by the actuator board to within 1 mmHg.
LO VEN = Hardware low venous alarm (actuator).
