1. A method to assist an operator in identifying a fault in a fluid path of a renal replacement therapy device comprising the steps of:
- a. drawing blood from a patient into the fluid path, passing the blood through the path in the device, and returning the blood from the fluid path into the patient;
b. detecting a fault in the fluid path;
c. displaying a pictorial diagram of the fluid path on the machine graphic display, and d. accentuating an element of the diagram of the fluid path where the fault has been detected.

Abstract
A graphical user interface for a medical instruments for a Renal Replacement Therapy is disclosed that includes a pictogram representation of the fluid path of an extracorporeal blood circuit that represents fluid lines, pumps and sensors. To assist the user in responding to alarms and rectifying faults in the system the source of a potential trouble is animated. The location of a trouble spot is easily identified by flashing of the corresponding element of the pictogram, change of color or thickness of a corresponding line.

27. A method for detecting a connection of an external sensor to a device having a controller electrically connected to a sensor coupling, said method comprising:
-
a. applying a voltage potential to a pull-up resistor electrically in the device and connected to the sensor coupling;
b. determining that the sensor is connected to the device if the applied voltage drops below a predetermined level, and c. determining that the sensor is not connected if the applied voltage level remains above the predetermined level.
