BASIC OPERATION
Powering the TRACER
If the batteries are weak, the BAT indicator will appear on the LCD. 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. An electrode must be
attached before turning the meter on.
Automatic Calibration
When the TRACER is turned on, it will enter the Automatic Calibration mode.
'SELF' and 'CAL' will appear on the display while calibration is in progress.
After the calibration is completed, the 'SELF' and 'CAL' display icons will
extinguish and both the main display and the bargraph will read ORP in mV.
Data Hold
Press the MODE/HOLD button to freeze the current reading. The HOLD display
icon will appear along with the held reading. The held reading will be stored in
the next 15-reading storage location. Press the MODE/HOLD button to return to
normal operation.
TESTING
Overview
ORP is the abbreviation for Oxidation Reduction Potential and represents the
oxidizing or reducing nature of a solution. The overall reactive tendency of a
solution can be determined from ORP measurements.
ORP Display
When the electrode is placed in a solution, the main display and bar graph will
indicate the ORP reading. Readings f ash until they have stabilized. The bar
graph is 'center zero', i.e. at 500mV there is no display. As the readings increase
from 0 to 1000 mV the bar will move from the left to the right.
Getting Started
1.
Remove the cap from the bottom of the TRACER to expose the
surface electrode and reference junction.
2.
White KCL crystals may be present in the cap. Rinse the crystals with tap
water.
