    G 1500 Operation and maintenance | 6 CAUTION Damage! If the batteries have different charge levels, leaks and thus damage to the product can occur. – Use new, high-quality batteries! – Do not use different types of batteries! – Remove depleted batteries and dispose of them at a suitable collection point!
  • Page 18 6 | Operation and maintenance G 1500 Prerequisite – The product is switched on. Instruction 1. Carefully remove the protective cap from the electrode. 2. Rinse off the electrode with distilled or deionised water. 3. Press function key F1 for 1 second to open the Calibration menu. Start 1.
  • Page 19 G 1500 Operation and maintenance | 6 NOTE Measure the temperature of the buffer solution with a thermometer. The exact value of the buffer solution is temperature dependent and can be determined based on the tables provided. NOTE Always use fresh buffer solutions! 6.3.1.2 Buffer solutions...
  • Page 20 6 | Operation and maintenance G 1500 NOTE Automatic calibration can also be carried out with the pre-mixed PHL buffer solutions. Since the temperature compensation relates to the GPH capsules, an error of a few hundredths pH should be taken into account, depending on the temperature. Refer also to the differences in the tables of the buffer solutions in Buffer solutions [} p. 19].

    6 | Operation and maintenance G 1500 Outcome of an action After successful completion of the calibration the assessment of the electrode condi- tion is displayed briefly in percent. Then, the current measurement is shown in the dis- play again. A low value can be the result of the age of the electrode, contaminated or old buffer solutions or impurities on the BNC connector.
