- Page 11 line displays the sample temperature. If measurements are taken in different samples successively, rinse the probe tip thoroughly to eliminate cross‑contamination. For better ac‑ † curacy, frequent calibration of the pH sensor with the meter is recommended. In addition, the meter must be recalibrated whenever: a) The pH electrode is replaced.
- 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).

If there is still only 1 bar or 1 bar blinking, replace the probe.

BATTERY REPLACEMENT When the remaining battery life is less than 10% the battery tag blinks on the display to warn the user. Battery Error Prevention System (BEPS) If the battery is too weak (“0%”) the display shows “bAtt“, “DEAD“ for few seconds then the meter power off. Immediately replace the batteries with new ones. - Page 17 HI7030M 12880 μS/cm solution, 230 mL bottle HI7031M 1413 μS/cm solution, 230 mL bottle HI7032M 1382 ppm (mg/L) solution, 230 mL bottle HI70038M 6.44 ppt (g/L) solution, 230 mL HI70442M 1500 ppm (mg/L) solution, 230 mL HI70300M pH electrode storage solution, 230 mL HI7061M pH electrode cleaning solution, 230 mL HI710028...
