Section 4: Troubleshooting and Preventive Maintenance

Symptom

Probable Causes / Possible Solutions

Insufficient sweat rate or insufficient

sweat for Sweat Analysis to

complete.
(See also Error Message

Troubleshooting below.)

Probable Causes:

Insufficient sweat may occur for a variety of reasons and varies

depending upon patient. Physiological factors, such as the patient’s

age, weight, race, and hydration level may contribute to insufficient

sweat, as well as other physiological factors (e.g. anhidrosis,

hypohidrosis).

Possible Solutions:

If an adequate sweat sample is not obtained, repeat testing should

occur as soon as is practical. This could be the same day or the

following day. The sweat test should only be repeated once on any

given day.†

The patient should be well hydrated and free of acute illness.

Check that the Pilogel is within the expiration date.

Nanoduct resets during a test.

Probable Causes:

Low battery voltage.

Electrostatic discharge to the Nanoduct’s face, enclosure,

connectors, or electrodes may cause the Nanoduct to reset (see

Appendix J).

Possible Solutions:

Replace all four batteries.

Repeat the sweat test one time.†

If the problem persists, contact ELITechGroup for further instructions.

Iontophoresis process stops

prematurely.

Probable Causes:

Low battery voltage.

Electrodes not properly latched with locking ring or cable becoming

detached from Nanoduct.

Holders not adequately secured to patient.

Damaged electrode cable assembly.

Possible Solutions:

Replace all four batteries.

Ensure both electrodes are latched with locking ring and that the

cable is properly connected to the Nanoduct.

Ensure holders are secured with adequate tightness to the patient’s

limb. Do not overtighten and impede blood circulation.

Inspect the electrode cable assembly for any damage. Do not use

electrodes if there is any damage to the cable insulation or if there

are exposed bare wires.

Repeat the sweat test one time.†

If the problem persists, contact ELITechGroup for further instructions.
