What should I do to change the capacity of the H-1700 (for titration) buret cylinder?

The dripping doesn’t proceed even after starting titration normally.

The buret suddenly stops moving up and down.

I purchased a reference electrode but there are something like salt crystals attached to the electrode.

It seems that the internal liquid of the electrode is running out quickly. What is the average?

What is the difference between a composite electrode and a single electrode?

What is the replenishment timing and replenishment rate of the electrode internal liquid?

Please tell me the difference between indicating electrode and comparative electrode.

Does the amount of pure water dilution have an impact on titration levels?

The capabilities of the pure water (solvent) emission pump in the auto-cycler 2000 series are too weak and cannot emit it all.
