BASIC OPERATION
Powering the TRACER
If the batteries are weak, the
BAT
indicator will appear on the display. Press
the ON/OFF button to turn the TRACER on or off. The auto power off feature
will shut the TRACER off automatically after 10 minutes of inactivity.
Automatic 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. An electrode
must be attached before turning the meter on.
Changing the Displayed Temperature Units
Press and hold the CAL button for approximately 3 seconds. The
°C
or
°F
icon
will change first and the numerical temperature value will change only after
the button is released.
NOTE: If the calibration mode is accidentally accessed and
CAL
appears on
the display, turn the TRACER off and begin again.
Data Hold
Press the MODE button to freeze the current reading. The
HOLD
display icon
will appear along with the held reading. The held reading will be stored in
memory. Press the MODE button to return to normal operation.
DISPLAY MESSAGES
CAL Reminder
When the TRACER is turned on for the 15th time, without recalibration the
CAL
icon will appear on the display indicating the the TRACER may require
calibration. Some applications may require recalibration of the electrode
sooner than others. The
CAL
display is a reminder and will turn off when the
pH electrode is recalibrated.
RENEW
A flashing
“RENEW”
warning indicates that the probe may be nearing the end
of its useful life. If cleaning or recalibration does not cause the
Renew
icon
to disappear, replace the electrode (see optional accessories). The
Renew
display appears when the output of the pH electrode fails a diagnostic test.
