-300 to +500 mmHg with 3 automatically set time-delayed alarm
window limit values (± 60, ± 80, and ± 100 mmHg of actual
pressure (Single Needle  80 mmHg).
-80 to +500 mmHg with 3 fixed window limit values of ±60, ±80,
and ± 100 mmHg of actual pressure. There is also an
asymmetric range initially set to ±80 mmHg which increases the
lower limit after 60 seconds (Single Needle ± 80 mmHg).
± 20 mmHg or ± 10% of indicated reading, whichever is greater
+60 to –520 mmHg with automatically set time delayed window
limit values of  60 (conventional dialysis) and  40 mmHg (high
flux dialysis). Compensation for upward drift.
Ultrasonic impulses detect fluid level in the drip chamber.
Optical transmission used to detect opaque or non-opaque
presence in the blood tubing.
Closes with any blood alarm
Allows the level in the drip chamber to rise to maintain the
desired fluid level in the drip chamber
Two color light source transmitter / sensor with a resolution of:
minor > 0.35 ml/min of blood (hematocrit = 25%)
alarm > 0.45 ml/min of blood (hematocrit = 25%)

Dialysate flow rate at 100 ml/min: Accuracy (on total volume
removed): ±(1% UF rate + 18 ml/hr)
Dialysate flow rate at 500 ml/min: Accuracy (on total volume
removed): ±(1% UF rate + 30 ml/hr)
Dialysate flow rate at 800 ml/min: Accuracy (on total volume
removed): ±(1% UF rate + 48 ml/hr)

Eight UF profiles are available for the removal of fluid from the
patient. Four are preset and four may be defined by the user.
0-9:59 hours auto transfer from UF time, counting down in 1-
minute increments. Can adjust manually.
