a test cycle, after pressing "Leakage resolved" Mastertronic will immediately be
followed by an automatic empty procedure, and then also a rinsing procedure.

Maintenance

Change external hoses

We recommend to change the external hoses every 8 months, and it very important
to use exact the same Inner Diameter as original (3.2mm) and same length as
we provide from start, 2 m for all the external hoses.
nor the diameter of the external hoses!

Change hoses in pump

We recommend to change the hose in the stepper every 8 months, and the hoses
in pump A,B,C every 12 months. Put the needle in "maintenance position" , when
changing the stepper hose, and in "standby position" when changing hoses in pump
A-C. For tips on how to change the hoses check out www.Focustronic.net for a video.

Recalibration

Calibration is to be done around 8 weeks. The machine will give you an alert when
its time to calibrate, as a reminder.

Descale/Clean the reaction chamber

Due to the reagents containing colour dyes and also carbonate deposits, its
advisable to make regular cleaning and descaling of the reaction chamber. The
interval depends on the measure frequency, but around every 4 weeks is a good rule
to keep consistent results every time.
Descaling
• Make sure the machine is in standby mode and the reagent chamber and
hoses are empty. Normally its totally emptied as all test cycles end with
an empty phase and also after a restart Mastertronic starts with an empty
program. But If there is, for some unpredictable reason, despite this water
in hoses and/or chambers, press "Empty Chambers and Hoses" from the
app menu.
• Open the app and press "Descaling Program"
NEVER change the length
