Maintenance
Change hoses in the pumps
Pump A and C
Every 6-8 months
Pump B and D
Every 12 months
OBS: Always use original hoses from FOCUSTRONIC for this purpose . We will
not guarantee precision/accuracy, nor safety, if you use other hoses than our
replacement hoses. It is of the utmost importance that these hoses are of correct
quality, diameter, length, with correctly positioned stops, and are specialized for this
machine and it´s pumps.
Changing the pH-electrode
The included pH electrode is of high quality and is specially chosen for this purpose.
If properly handled, it will last for 2-2.5 years. After these 2+ years it will need to be
replaced. You can purchase the electrode at Focustronic, or at the local dealer
where you bought the machine. When you replace the electrode you have to
unscrew the back-lid and in the upper right corner of the circuit board connect the
BNC cable to the BNC-contact. Be very careful not to touch the electronics on the
circuit board. If you are concerned about performing this task, please contact
Focustronics support and we will guide you through it. After that, follow the
instructions on page 11, from point 2 and onwards.
Recalibration
pH-electrode
Recalibration around every 6 months. A brand new electrode could manage a
longer interval, but an electrode after 1-2 years will require some more frequent
calibration than before, so 6 months is appropriate independently of the age of the
electrode. The electrode will last around 2.5 years if handled properly.
Pumps
Pump A and C
Every 2-4 weeks. You can always run the function ” test pump accuracy ” to check if
calibration is needed, as the interval could di ff er depending on the age of the hose
inside the pump. Thus 2-4 weeks in only a guideline, and could vary. The machine
will give you an alert when time to calibrate, as a reminder.
