2.3.6.4 TEMPERATURE CONTROL CALIBRATION (METHOD 4)
Perform this section only if the machine is equipped with the following:
- Functional Software v2.25 or greater, the machine has the OLC option
installed AND the Temp Comp option is enabled and the slow flow option is
enabled.
Note: The Temp Comp option is only present in Functional Software v2.25 or
greater and uses post temperature sensor NTC44. Do not attempt to calibrate a
non-OLC machine with the Temp Comp option enabled since NTC44 is not
present and an Operator Error will occur.
If the slow flow option is enabled, the Temp Control calibration is done in two
parts. The DAC and temperature monitor calibration is performed at 500ml/min
flow rate and then it is calibrated at a 100ml/min flow rate.
Replace any panels that have been removed so that the machine is closed up as it
would be in normal operation. It is important for this calibration that ventilation
around the hydraulics unit be the same as it is when the machine is used for dialysis.
From the Calibrate Sensors screen, select the Temp Control screen button.
