Sample should be below 122 °F (50 °C). Let cool if necessary.
NOTE: The purpose of ATC in this meter is to maintain electrode calibration
across the capability range of 32-194 °F (0-90 °C). It is recommended that
wort samples be cooled to room temperature (68 °F/20 °C) before testing.
This allows better comparison of measurements at different temperatures
due to the natural change in wort pH due to changes in temperature, and
improves electrode life.
1. Remove cap. Press ON/OFF to turn meter on.
2. Dip sensor in sample water.
3. Record pH after reading becomes stable and display stops fl ashing.
4. Press MODE to hold reading and store reading in memory
5. Press ON/OFF to shut meter off.
6. Store in pH 4.0 buffer. Store upright.
Daily Calibration Procedure
1. Fill tube (0715) to 20 mL line with distilled water. Pour into small container.
Add pH 7.0 Mini Buffer Tablet (3984A). Stir until tablet disintegrates.
2. Remove cap. Press ON/OFF to turn the meter on.
3. Dip sensor in buffer.
4. Press CAL. END will be displayed and the circled 7 indicator will be
displayed.
5. Repeat Steps 1–4 with pH 4 Mini Buffer Tablet (3983A). Save pH 4 Buffer
to use as storage solution. Tester is calibrated.
Before First Use or After Storage
1. Hold meter by top battery compartment. Swiftly tap back of meter
downward into palm - not a hard surface - to move electrolyte into
electrode tip.
2. Remove cap. Soak electrode in pH 4.0 buffer or tap water for 10 minutes.
