Page 9: Operational Guide
OPERATIONAL GUIDE Each meter is supplied with batteries. Before using the meter for the first time, open the battery compartment and insert batteries, observing the polarity (see “Battery Replacement“). CONNECTING THE ELECTRODE With the meter turned off, connect the HI12973 probe to the DIN socket on the bottom of the meter by aligning the pins and pushing in the plug firmly. - Page 10 - If the readings are out of range, the nearest range limits are displayed blinking (e.g. -2.00 pH -5.0 °C). SELECTING MEASUREMENT RANGE While in measurement mode, press the SET button to select pH or pH‑mV measurement on the first LCD line. FREEZING MEASUREMENT VALUES While in measurement mode, press and hold the SET button until “HOLD“...
- Page 11 The LCD displays the pH value (automatically compensated for temperature) on the primary LCD, the ORP value on the secondary LCD, while the tertiary LCD line displays the sample temperature. If measurements are taken in different samples successively, rinse the probe tip thoroughly in distilled or deionized water to eliminate cross‑...
- Page 12 Two-point calibration Proceed with steps 1 through 3 under single‑point calibration using 7.01 pH (pH 6.86 for NIST) buffer first. Then follow steps below: The ”pH 4.01 USE” message is then displayed. Place the probe in the second calibration buffer (pH 4.01 or 10.01, or, if using NIST, pH 4.01 or 9.18).
- Page 13 5 bars: excellent condition 4 bars: very good condition 3 bars: good condition 2 bars: fair condition 1 bar: poor condition 1 bar blinking: very poor condition With 1 bar it is recommended to clean the electrode and recalibrate. If there is still only 1 bar or 1 bar blinking replace the probe.
