OPERATIONAL GUIDE
INITIAL PREPARATION
Each meter is supplied complete with a 9V battery. Remove the battery compartment cover on the back of the meter and install the battery while paying attention to its polarity. Connect the probe to the DIN socket on the top of the meter by aligning the pins with the socket and pushing in the plug. Always remove the probe protective cap before taking any measurements, and make sure the meter has been calibrated. Turn the meter on by pressing the ON/OFF key.
TAKING pH MEASUREMENTS
If the probe has been left dry, soak the tip in HI 70300 storage solution for a few minutes to reactivate it. · To take a pH measurement simply submerge the tip (4cm/1½") of the probe into the sample to be tested. · Stir briefly and wait a couple of minutes for the reading to adjust and stabilize. · If measurements are taken in different samples successively, it is recommended to rinse (clean) the probe thoroughly to eliminate cross-contamination. After cleaning, it is recommended to rinse the probe with some of the next sample to be measured.
TAKING EC/TDS MEASUREMENTS
· Immerse the tip of the probe (4cm/1½") into the sample to be tested. If possible, use plastic beakers or containers to minimize any EMC interference. · Tap the probe lightly on the bottom of the beaker to remove any air bubbles which may be trapped inside the tip.

· Select the appropriate measurement range (EC or TDS).
· Wait for a couple of minutes for the temperature sensor to reach thermal equilibrium. The display then shows the measurement automatically compensated for temperature with the appropriate following indication: "mS" tag indicates the meter is in EC mode, while no symbol indicates the meter is in TDS mode.
TAKING TEMPERATURE MEASUREMENTS (not for HI 9813)
· Submerge the tip (4cm/1½") of the probe into the sample to be tested. · Stir briefly and wait a couple of minutes for the reading to adjust and stabilize. The display shows the temperature value.
Note: If the display shows only a "1" on the far left hand side, the reading is out of range. Note: It is recommended to clean often the probe with HI 700661 Cleaning Solution. Note: After measurements have been completed, the instrument should be switched off, and the probe cleaned and covered with the protective cap.
pH CALIBRATION
For greatest accuracy, frequent calibration of the instrument is recommended. The instrument should be recalibrated for pH: a) Whenever the electrode is replaced. e) Whenever the CAL-CHECK test fails (HI 9813-6 only).
PREPARATION
Pour small quantities of pH 7. 01 (HI 7007) or pH 4. 01 (HI 7004) or pH 10. 01 (HI 7010) solution into a clean beaker. To obtain accurate readings, use pH 7. 01 (HI 7007) if you are going to measure neutral or close to neutral samples, pH 4. 01 (HI 7004) if you are going to measure acidic samples or pH 10. 01 (HI 7010) for alkaline measurements. If you need to calibrate to NBS standards, use pH 6. 86 (HI 7006) instead of pH 7. 01 and pH 9. 18 (HI 7009) instead of pH 10. 01.
PROCEDURE
· Connect the probe and switch the meter on, then press the "pH" key to display pH measurement. · Remove the protective cap from the probe, rinse and immerse it in the buffer and stir gently. Wait a couple of minutes for the reading to stabilize. [. . . ] Operation of these instruments in residential areas could cause unacceptable interferences to radio and TV equipment. The glass bulb at the end of the electrode is sensitive to electrostatic discharges. Avoid touching this glass bulb at all times. During operation, ESD wrist straps should be worn to avoid possible damage to the electrode by electrostatic discharges. [. . . ]
