normal.
If you see drops falling into the beaker, but the number of drops displayed on the
screen does not change, remove the pH cover and check whether the position of the
reagent outlet is normal.
3.
Add KH reagent
KH reagent can be added normally by manually operating KH reagent pump.
If reagent is not added normally after operation, check whether the pipeline connection
is normal.
4.
Magnetic stirring
Manually control the magnetic stirring operation, check whether the magnetic stirring
can operate normally, stir the liquid to rotate, and the magnetic rotor rotates along a
center during operation without shaking.
If the rotation is too intense, resulting in liquid splashing, you can reduce the intensity
of magnetic stirring on the App.
5.
Waste liquid discharge pump
Manually operate the waste liquid discharge pump until the liquid in the beaker is
drained.
If the waste liquid cannot be discharged completely, check whether the waste liquid
discharge pipe is in the beaker, whether the pipe inlet is attached to the bottom of the
beaker, and if the waste liquid discharge pipe does not touch the bottom of the beaker,
the waste liquid cannot be discharged completely.
