Iontophoresis
Sweat Analysis
Recall Reading
Electrode Socket
The electrode socket on the top of the enclosure connects the electrode/sensor
cable assembly to provide electrical current for sweat stimulation and to receive
sensor signals to the induction/analysis module during the analysis phase.
Keypad Keys
ON
The ON key turns the instrument on when pressed. The ON key is also used in
conjunction with the SELECT key to access the Setup Menu.
OFF
The OFF key powers the instrument off. Pressing the OFF key cancels all
operations and turns power to the module off.
NOTE: To preserve battery power, leave power off except while performing a
test. During idle periods the instrument shuts down automatically after 10 minutes
and must be turned on again to complete testing or retrieve a result.
SELECT
The SELECT key scrolls through menu selections and increments parameter
settings. Use the SELECT key in conjunction with the ON key when accessing
the SETUP MENU.
ENTER
The ENTER key selects menu selections, advances through menu screens, and
starts the iontophoresis and analysis phases of the sweat test. A warning tone
sounds if a fault condition occurs–such as an open electrode or circuit fault. The
fault condition is displayed and reset by pressing ENTER.

Display

The LCD alphanumeric read-out displays all functions and results as they occur,
including iontophoresis status and analysis results, plus the time and date of the
last procedure. The user responds to prompts on the display to activate various
functions. The instrument emits a short beep tone at the start and end of each
operation.
The instrument displays conductivity measurements in mmol/L (equivalent NaCl)
during analysis. If desired, display readings can be suppressed so readings are
not visible, but can be recalled later.
Low Battery Indicator
If the battery voltage drops below a preset level at power-up, a "Low Battery"
message appears on the display. When this indicator first appears, it is possible
to complete a small number of tests before replacing the batteries. If battery
power is too low to complete a test, the module automatically shuts off and
iontophoresis cannot be started. The batteries must be replaced to continue.
Refer to Section 2.1 to replace the batteries.
NOTE: Use only four standard alkaline AA cells to power the Nanoduct. Using
other types of AA cells may cause low battery indicator inaccuracy.
