8.3 To replace the probe pre-membraned cap
1) Unscrew counter clockwise the pre-membraned cap from the probe
sensing tip and discard.
2) Wash the probe under running water.
3) Mount the nozzle tip onto the syringe provided. Fill the syringe with the
refill solution through the tip of the plastic bottle.
4) Hold the probe upside down. Insert the nozzle tip into one of the 4 holes
surrounding the silver cathode. Inject the fill solution into the probe body
until solution leaks out from the fill hole (approximately 5 mL).
5) Replace pre-membraned cap by tightening clockwise until hand tightened.
6) Allow at least 1 hour for the electrode to equilibrate before usage.
