4 Check – dialysate flow
4.1 In the service mode, select CALIBRATE.
Basic requirements:
The hemodialysis system
must be closed.
Flow on, flow 800 ml/min
Check flow.
Desired value: 770 ml/min to 830 ml/min
5 Check – temperature
5.1 In the service mode, select CALIBRATE.
Basic requirements:
The hemodialysis system
must be closed.
Temperature 37 °C, flow on, flow 500 ml/min,
Response time approx. 10 min.
Check PT07 (temperature).
Desired value: 36.8 °C to 37.2 °C (display on hemodialysis system)
Measure the reference temperature with an external measuring instrument.
Difference = Reference temperature minus PT07
Desired value – difference: –0.5 °C to +0.2 °C
Example:
PT07: 37 °C
Desired value reference temperature: 36.5 °C to 37.2 °C
6 Check – conductivity
6.1 In the service mode, select CALIBRATE.
Basic requirements:
The hemodialysis system
must be closed.
External measuring instrument (e.g. UMED) connected for at least 5 minutes.
Temperature 37 °C, flow on
Check CD7 (conductivity).
Desired value: approx. 13.5 mS/cm to approx. 14.5 mS/cm
Measure the reference conductivity with an external measuring instrument.
Difference = Reference conductivity minus CD7
Desired value – difference:
±
0.2 mS/cm
7 Check – blood leak detector
In the service mode, select CALIBRATE.
Basic requirements:
The hemodialysis system
must be closed. (Avoid external light.)
Temperature of approx. 37 °C achieved, flow on, flow 500 ml/min,
7.1 Check the blood leak:
Desired value: 4.8 V to 5.2 V
7.3 Check the dimness:
Desired value: 4.8 V to 5.2 V
No. Description
