## FAQ

### How many clicks does a typical dosing pen have per rotation?

Common models use 50, 100, or 200 detents per full rotation. More detents mean finer control but slower dialing. Check the spec sheet for your pen's exact count.

### What causes a dosing pen to lose click accuracy?

Worn detent spring, dried diluent crystals inside the gear, or physical damage from forcing the dial past its stop are the top reasons. Regular rinsing and gentle use preserve accuracy.

### Can I clean a sticky click dial without disassembly?

Yes. Flush the internal cavity with distilled water through the dispense tip while dialing back and forth, then dry completely. If stickiness persists, disassemble for deeper cleaning.
