Maintenance position
Maintenance position is used when you change the hose of the stepper pump,
or clean the chamber.
Standby position
Standby position is ideally never used, as all algorithms and failsafes always
make sure the needle is in the correct position. So this function is just to take
the needle to the highest position above the reaction chamber in case of any
unpredicted errors
Carousel Movement
With this function you move the carousel to desired position to take out or reinsert a
reagent vial.
Never rotate the carousel by hand
Unlock Device
After you have started a brand new machine for very first time from the factory you

sure the syringe is empty. So this function is if something unpredictable
happens and will take the syringe to the bottom position.
Empty Waste Container
This resets the counter for the waste container.
Reset Pump Calibration
This function is normally not to be used, as the machine comes from the factory with
a factory calibration, and after that users do their own calibration. But if you for some
reason, mostly after contact with tech support, need to reset calibration data back to
factory values, you can use this button.
After a reset like this, you must proceed
to calibrate the pumps.
Leakage resolved
If a leakage occurs, Mastertronic will stop and display a leak error message on the
LCD. When you have dried up the water carefully, press “Leakage resolved”, and
Mastertronic will resume (if there is absolutely no water or humid residuals on the
