Attempting to enter a time of 0:62. Until the CONFIRM key or another parameter
entry button is selected, this is allowed because the operator may be intending to enter
6:20, which is valid.
Attempting to enter a value that is above or below the allowed range of a parameter
entry box. For instance, entering a Na value above 155 mEq/l is not allowed and
therefore is an invalid entry.
When the
/ (up or down) keys are used to enter a value, the scrolling will stop at the
upper or lower allowed values. If the operator enters an invalid time with the keypad, a
message is shown in the Dialogue Box with the erroneous value and a message to press the
Escape key. If an invalid parameter other than time is entered, the value will be entered as
the lowest or highest allowed value, accompanied with a message in the Dialogue Box.

Dialysate Screen Settings
The “Dialysate” screen is displayed automatically at start up. It is also shown when either the
Dialysate button or Conductivity button in the “Home” screen is pressed.
Within the “Dialysate” screen, the concentrations of base sodium (Na
+
), bicarbonate, and
other constituents are displayed. The Theoretical Conductivity (TCD)—the conductivity of
the dialysate based on these concentrations—is displayed in the left side of the screen. The
actual conductivity of the dialysate is displayed on the right side, above the Conductivity bar
graph.
4) You can enter the values
for all the buttons
(highlighting them and using
the data entry keypad for
each one) then press the
CONFIRM key to save them
all at once.
