INTRODUCTION Congratulations on your purchase of the TRACER pH PockeTester. The TRACER is a revolutionary, first of its kind measurement device that offers direct reading of pH from 0.01 to 14.00 pH. The advantages of the TRACER to the user include ease of use and maintenance, high accuracy, automatic calibration, and fast response. The TRACER offers simultaneous pH and Temperature displays and a 15-reading memory storage. Careful use and maintenance will provide years of reliable service.

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. 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.
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. pH TESTING Overview pH is a unit of measure (ranging from 0 to 14 pH) indicating the degree of acidity or alkalinity of a solution.
Preparation of Buffers 1. Fill a sample cup with 20 mL of distilled or deionized water. 2. Add one buffer tablet: pH 4.0 Code 3983A pH 7.0 Code 3984A pH 10.0 Code 3985A 3. Use the tablet crusher (0175) to crush the tablet. Stir until the tablet has disintegrated. NOTE: Buffers should be prepared fresh daily. pH Calibration The TRACER can be calibrated at 1, 2 or 3 points.
9. Always turn the meter off and then on before calibrating to allow sufficient time to complete the calibrations during one power cycle. If the meter auto powers off during calibration the calibrations remain valid, but new calibrations will turn the circled indicators off. pH Measurement 1. Place the electrode in the test sample. 2. Record the pH after the reading becomes stable and the display stops flashing. The main display will indicate the pH in numeric units from 0.00 to 14.00.
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.
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 and user calibrations will be cleared. A new user calibration will be required. Factory calibrations will be retained.
TROUBLESHOOTING Problem Cause Action Power on but no display Batteries Insert batteries Batteries Verify correct polarity Batteries Replace batteries Electrode Immerse electrode more deeply in sample Electrode Condition electrode before first use Electrode Remove air bubbles caught under electrode Electrode Clean electrode Electrode Replace electrode Clogged junction Soak in 4.07M Potassium Chloride (KCl) at 60°C for 30 minutes Strong alkaline measurement Soak in 0.
Problem Cause Action Erratic LCD display Samples have low ionic strength (lack salt); e.g. distilled, deionized, boiled, lake water (high pressure) For each 50 mL of sample add 1 drop (50 mL) of saturated Potassium Chloride (KCl). No alteration in pH will occur by inert KCl.
