92. Rinse the pH and temperature (if applicable) sensors with distilledwater and immerse in the sample to be measured. Remove any airbubbles trapped around the electrode by shaking or stirring theelectrode.3. Allow sufficient time for the display to stabilize. The unit will notlock the measurement on the display, so it is up to the user todetermine when the measurement is stable.TEMPERATURE MEASUREMENTSThe pH1000A can measure temperature independently with the 1102pH/ATC probe or the 1103 temperature probe. Place the sensor in thesample and the unit will display the measured temperature.mV MEASUREMENTSORP measurements can be made with the YSI 115-1 (item # 605376)electrode, but any ORP electrode with a BNC connection can be used.MEASUREMENTS IN THE mV AUTOLOCK MODE1. Press the Mode key until the “mV” icon and “AUTO” icon light up.2. Rinse the electrode with distilled water and immerse in the sample.3. Press the Meas. / Effic. key. The “WAIT” icon will start flashing. Theunit is waiting for a stable measurement.4. When the “WAIT” icon disappears and the “LOCK” icon appears,the reading is frozen and will not respond to further changes.• For samples that are inherently unstable, the unit will notAUTOLOCK. In this case, use the mV NON- AUTOLOCK modefor measurements.MEASUREMENTS IN THE mV NON-AUTOLOCK MODE1. Press the Mode key until the “mV” icon lights up. The “AUTO” iconwill not be on the display when in the NON-AUTOLOCK mode.2. Rinse the electrode with distilled water and immerse in the sampleto be measured.3.
