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.

Display

When the electrode is placed in a solution, the main display and bar

graph will indicate the ORP reading. Readings flash 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

flat surface electrode and reference junction.

2. White KCL crystals may be present in the cap. Rinse the crystals

with tap water.

ORP Measurement

1. Press the ON/OFF button to turn the meter on. Place the electrode

½” to 1” into the test sample .

2. Stir once and let the reading stabilize for 1 to 3 minutes.

The main display will indicate the ORP in numeric units from 0 to

1000mV. The bar graph will also display the ORP value. As the

ORP increases, the bar graph will move from left to right.

3. Press the ON/OFF button to turn the meter off. Rinse the electrode

with distilled water. Replace cap.

Storing Readings

1. After the reading is made press the MODE/HOLD button to store

the current reading. The HOLD icon will be displayed. The storage

location number will also be displayed followed by the reading

being stored.

2. Press the MODE/HOLD

button to return to normal

operation.

3. Repeat step 1 to store the next

reading.

4. If an attempt is made to store

more than 15 readings, the

stored readings (starting with

the first reading) will be overwritten.

Recalling Stored Readings

NOTE: First ensure that the HOLD symbol is not displayed. If it is, exit

the HOLD function by pressing the MODE/HOLD button.

1. Press the CAL/RECALL button once and then press the MODE

button immediately after CAL is displayed; the location number (1

through 15) will flash. If the CAL mode is accidentally accessed

(display flashing), press the CAL/RECALL button again to exit.

2. The last stored reading taken will be displayed first. To advance

through the stored readings, press the MODE/HOLD button. The

location number is displayed first, followed by the reading stored in

that location.

3. To exit the recall mode, press the CAL/RECALL button and the

TRACER will return to normal operation.

If the batteries are removed, any stored readings will be discarded.

MAINTENANCE

Storage

To preserve electrode life keep the sponge in the protective cap soaked

with tap water. Dot not use deionized or distilled water.Cap TRACER

when not in use. Store vertically.

Battery Replacement

1. Twist off the battery compartment cap.

2. Hold the battery housing in place with one finger. Remove the

battery carrier by pulling on the small tabs.

3. Replace the four CR2032 batteries. Observe polarity.

4. Replace the battery compartment cap.

NOTE: If the batteries are removed, stored data will be cleared.

Factory calibrations will be retained.

Replacing the Electrode

The TRACER is shipped with an electrode attached. If the electrode

needs to be replaced, follow these steps for removing and connecting

electrodes.

1. Turn meter off.

2. To remove the electrode, turn the collar counter-clockwise and

remove it.

3. Gently rock the electrode from side to side, pulling it downwards,

until it disconnects from the meter.

4. To attach an electrode, carefully plug the electrode into the meter

socket. Note that the electrode connector is keyed to ensure a

proper connection.

5. Tighten the electrode collar firmly enough to make a good seal. A

rubber gasket will seal the electrode with the meter.

Expand Your TRACER

Interchangeable electrodes are available to convert the ORP TRACER

to a Total Chlorine TRACER or a pH TRACER.

Remember to ask for instructions and appropriate reagent or buffer

tablets when ordering Total Chlorine or pH electrodes.

Total Chlorine TRACER Electrode, 0.00-10.00 ppm Code 1732

The Total Chlorine TRACER Electrode (Code

1732) requires the use of TRACER TCL Tablets.

Order Code 7044A-J (100 pack).

pH TRACER Electrode, 0.00 - 14.00 pH Code 1733

The pH TRACER Electrode is used with pH 4.0, 7.0

and 10.0 buffers. Order using the following codes:

pH 4.0 Mini Buffer Tablets (100) Code 3983A-J

pH 7.0 Mini Buffer Tablets (100) Code 3984A-J

pH 10.0 Mini Buffer Tablets (100) Code 3985A-J
