Expected value / function
In the dialysis mode collect 60 ml of dialysate in
an appropriate graduated cylinder.
60 strokes = 60 ml (±0.5 ml).
Correct the setting of the UF pump, if necessary.
Collect the volume of two consecutive balancing
chamber switchings.
The average volume must be 30 ml ±1 ml.
Adjust according to calibration instructions, if ne-
cessary.
Adjust according to calibration instructions, if ne-
cessary.
Use a reference meter connected between the
dialyzer couplings to verify that the temperature is
37 °C ±0.5 °C.
Correct any deviations with the calibration pro-
gram.
The temperature shown on the monitor front pa-
nel must be 37 °C ±0.5 °C.
Correct any deviations with the calibration pro-
gram.
Collect fluid on the drain using a measuring cylin-
der.
800 ml/min (desired value: 765 to 837 ml/min)
500 ml/min (desired value: 471 to 528 ml/min)
300 ml/min (desired value: 279 to 321 ml/min)
Adjust according to calibration instructions, if ne-
cessary.
Perform a TMP test according to the calibration
instructions.

Measure the conductivity with a reference meter
connected bewteen the dialyzer couplings.
The conductivity measured must agree with the
value on the reference meter.
Correct any deviations with the calibration pro-
gram.
