5.2. Changing the Internal Filled Gel (IFG) If the zero point of the A420-FCL does not meet the listed specifications it may be necessary to change the IFG. The IFG also needs be changed if the stainless-steel ring (counter electrode) is not submersed in the water when the electrode is powered for more than 5 minutes. -
