BASIC OPERATION
Powering the TRACER
If the batteries are weak, the BAT indicator will appear on the display.
Press the ON/OFF key to turn the TRACER on or off. The auto power off
feature will shut the TRACER off automatically after 10 minutes of
inactivity.
Electrode Recognition
When the TRACER is turned on, it will recognize the type of electrode
that is connected and will display the appropriate unit of measure.
Automatic Calibration
NOTE: The automatic calibration process calibrates internal circuitry for
drift. This does not calibrate the electrode.
The TRACER should not be immersed in a solution until after the unit is
turned on. When the TRACER is turned on, it will automatically self
calibrate and the
SELF
and
CAL
icons will be displayed. These icons will
disappear after the self calibration is complete. The main display and bar
graph will then read the Total Chlorine concentration in ppm units. The
bar graph will read 0 ppm (far left), 5 ppm (center), and 10 ppm (far
right). The unit of measure for the lower temperature display will be
°C
or
°F as selected. The readings on the display will flash until they have
stabilized.
Changing the Displayed Temperature Units
Press and hold the CAL/RECALL button for approximately 3 seconds.
The
°C or °F icon will change first and temperature readings will change
only after the button has been released.
Low Battery Indicator
The “BAT” indicator will be displayed when the batteries become weak.
Refer to the Maintenance Section for battery replacement information.
