Symptom Probable Cause/Solution
Device appears to be locked
up or is inoperable with the
display on.
Probable Causes:
There are multiple reasons why a lockup may occur ranging from a hardware
malfunction to a software problem. Often times it is hard to pinpoint the
exact problem or the series of events that may have led to the problem.
Possible Solutions:
Reset the device by pressing and holding down the power switch for 4-5
seconds. The device powers off. Turn the device back on by pressing the
power switch for 1-2 seconds.
Insufficient sweat occurs.
Probable Causes:
Insufficient sweat may occur for a variety of reasons and varies depending
upon patient physiological factors. 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).
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.
Possible Solutions:
The patient should be well hydrated and free of acute illness.
Check the polarity of the electrodes. Pilocarpine will not be delivered under
the black electrode. The collector must be placed precisely over the location
of the red electrode and attached securely.
Check that the Pilogel is within the expiration date.
See Appendix D – Procedure for High Skin Resistance.
Insufficient sweat occurs on a
regular basis.
Probable Cause:
High skin resistance or possible defect with the device.
Possible Solutions:
See Appendix D – Procedure for High Skin Resistance.
If insufficient sweat quantity occurs on a regular basis, contact ELITechGroup
for further instructions.
Date/Time is not maintained. Probable Cause:
The internal back-up battery for the real time clock (RTC) is discharged.
Possible Solutions:
Back-up battery needs to be replaced by qualified service personnel.
