Condition or cause Check and action
Normal actual conductivity
○[CD] electrode contaminated with dirt
such as CaCO3 or leak from
conductivity sensor
○Incorrect [CD] terminal connection
○Internal disconnection or short circuit
of [CD] harness
○Failure of main board
Check: Take dialysate sample from [SL] to measure conductivity by
specified method.
Action: Rinse the electrode with acetic acid followed by water rinsing
sufficiently.
If the dirt can not be removed, use specified detergent such
as CARON or SYUNMA to remove it after disassembling
conductivity sensor.
Check: Check no miss-wiring, loosening, corrosion and
disconnection of TM1 CD terminal of main board.
Action: If loosened, tighten the connection securely.
If miss-wired, correct.
If corroded or disconnected, replace harness with mew one.
Check: After disconnecting TM1 CD terminal from main board,
measure resistance between [CD] and [GND] to check no short
circuit, disconnection and fluctuation of measured resistance.
Action: Replace [CD] harness with new one.
Check: Change ambient temperature of main board to check whether
conductivity and temperature indications are changed.
Action: If incorrectly indicated, replace main board with new one.
