General Troubleshooting and Diagnosis

Symptom
Nothing happens when the On button
is pressed, display remains blank, or
is not responsive when buttons are
pressed.
Nanoduct immediately shuts off
after pressing On button or shuts off
during a test.
During Sweat Analysis, the display
does not change from "Please
Wait..."
Probable Causes / Possible Solutions
Probable Causes:
Low or dead batteries.
Potential malfunction causing a lock-up condition.
Possible Solutions:
Replace all four batteries.
Reset the Nanoduct.*
If the problem persists, contact ELITechGroup for further instructions.
Probable Causes:
Low battery voltage.
Possible Solutions:
Replace all four batteries.
Repeat the sweat test one time.†
If problem persists, there may be an issue with the Nanoduct. Contact
ELITechGroup for further information.
Probable Causes:
No sweat detected, possibly due to sensor cell not properly latched
with locking ring or holder not adequately secured to patient.
Cable may have become detached from sensor cell or Nanoduct.
Damaged electrode cable assembly.
Orifice on sensor cell blocked.
Possible Solutions:
Ensure sensor cell is latched with locking ring and that holder
secured with adequate tightness to the patient's limb. Do not
overtighten and impede blood circulation.
Ensure that the cable is properly connected to both sensor cell and
Nanoduct.
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. Replace electrode cable assembly.
Repeat the sweat test one time using a new sensor cell.†
The patient's sweat rate may be very low (see next row). Wait sufficient time
to allow sweat to flow. (Not to exceed 30 minutes.)
