INTERSCAN

department
for problems not on this list or if suggested corrective actions fail to address
the problem.
Symptom
Probably cause / Corrective action
Erroneous low readings
•
Sample straw is too shallow in the patient’s mouth. Straw should be inserted
at a depth of 1-2 inches at the back of the tongue.
•
Lips or teeth are pinching the straw. Me sure
patient’s lips/teeth are not
contacting the straw.
•
Patient is speaking or has mouth open during the 3-minute pre-sample
countdown. Be sure patient’s mouth remains closed during this period to
ensure adequate buildup of Volatile Sulfur Compounds (VSC).
•
Instrument may require calibration. If patient is executing proper sample
technique and low readings are still occurring, perform instrument calibration.
See section 7.
Erroneous high
readings
•
Patent is blowing or breathing into the straw. Be sure the patient is breathing
through the nose and not blowing into the straw.
Unit will not power up
•
Eject the SD card and/or remove the mini USB cable from the USB port and
re-attempt power up. Re-insert the SD card or re-connect the USB cable after
successful power up.
Trouble with menu
navigation or
powering down
•
Should the instrument “lock up” or if menu navigation functionality is
compromised, the user can perform an emergency shutdown by pressing
and holding the
POWER
button for 10 seconds to power the unit down from
any screen.
This should only be done if normal MAIN MENU screen power
down is not possible.
