    OPERATIONAL GUIDE OPERATIONAL GUIDE OPERATIONAL GUIDE OPERATIONAL GUIDE OPERATIONAL GUIDE POWER CONNECTION Plug the 12 VDC adapter into the power supply socket. Notes: • These instruments use non volatile memory to retain the pH, mV, temperature calibrations and all other settings, even when unplugged.
  • Page 7 If measurements are taken successively in different samples, it is recommended to rinse the electrode thoroughly with deionized water or tap water and then with some of the next sample to prevent cross-contamination. The pH reading is affected by temperature. In order to measure the pH accurately, the temperature effect must be compensated for.
  • Page 8 RELATIVE mV MEASUREMENTS (HI 2213) • Press RANGE until “rEL” message will be displayed on the secondary LCD line for one second and “mV” tag will blink. After one second the temperature will be displayed on the secondary LCD. The reading displayed by the instrument is equal to the difference between the current mV input value and relative mV offset established in the relative mV calibration.
