The Dynatron® ibox™ Iontophoresis Device
Error Messages
The following error messages may appear (flash) in the display window
during a treatment. The cause for the message is described along with
solutions that can be attempted to recover from the particular error.
Correction of the condition usually returns a treatment in progress back to
its state prior to the error.
“ELCTRD OFF”
- This error message is typically displayed when an
electrode becomes detached from the patient during a treatment.
This message is also displayed if an electrode is not making a proper
connection to the patient via the path from the device, through the
electrode cable, through the electrode clip, and through the electrode
itself.
Solutions: 1) Check that the electrode cable plugs are firmly inserted
into the Dynatron ibox output jacks.
2) Inspect the electrode cable wires for breaks or cracks.
3) Make sure that the electrode clips are securely attached to
the electrodes.
4) Check electrode(s) to make sure they are correctly attached
to the patient.
A treatment may be continued by first resolving the condition that initially
caused the error message followed by depression of the up arrow key
associated with the treatment channel.
“ELCTRD SHORT”
- This error message is displayed when the active
electrode wire becomes connected (touches/shorted) to the return
electrode wire. This message could also be displayed if a short or
connection occurs between the electrode wires anywhere along the path
of the wires, including the electrodes, clips, and plugs.
Solutions: 1) Check that the electrodes are not touching each other on
the patient.
2) Check that the electrode clips are not touching each other.
3) Carefully inspect the entire electrode cable for any shorted
wires caused by breaks in the wire. Replace the electrode
cable if any break or damage is found.
The treatment continues following correction of the short but the
treatment intensity will be scaled-back to 0.5 mA. The user must manually
reset the intensity to the level selected prior to the short condition.
“HIGH Z”
- This error message is displayed when the resistance/
impedance (“Z”) of active and return electrodes exceeds the nominal
resistance/impedance expected of these electrodes when applied to the
patient. Nominal impedance is between 6 and 10 KOhms. This situation
can occur if the electrodes are not properly contacting the skin of a
patient. When the resistance/impedance exceeds about 10 KOhms, but
is less than 50 KOhms, the HIGH Z message will be displayed until the
resistance/impedance is lowered into the normal range.
Solutions: 1) Check that the electrodes are properly attached to the
patient. Replace the electrodes and drug to be
administered if necessary.
2) Check that there are no defects in the electrodes being
used. Replace the electrodes and drug to be administered
if necessary.
3) Inspect the patient’s skin to verify that it has been properly
cleaned and prepared.
4) Verify that a drug has been instilled into the active
electrode.
5) Make sure that the electrode cable plugs are firmly inserted
into the output jacks.
6) Check that the electrode clips are securely attached to the
electrodes.
7) Inspect the electrode cable wires to make sure that there
are no breaks or damage.
