5.3.3 Storing powder dosing heads
For short-term and long-term storage of the powder
dosing heads, METTLER TOLEDO recommends using
storage containers to:
• reduce the risk of contamination
• reduce the quantity of humidity absorbed by the
powder
You can store the dosing heads right-side up (1) or
upside-down (2).

5.3.4 Avoiding electrostatic charges
When preparing sample vessels, electrostatic charge may build up. Electrostatic charges may make correct
dosing impossible or adversely affect the dosing result.
Factors increasing the amount of electric charges:
• using sample vessels made of plastic
• wearing latex gloves
The integrable antistatic kit is used to remove electrostatic charges from sample vessels. This antistatic kit is
especially designed for dosing purposes and consists of two ionizing electrodes, one placed on each side of
the weighing chamber. The electrodes can be activated automatically when dosing or tapping Start. Using
those two electrodes helps removing electrostatic charges from sample vessels.
Make sure to install a dosing head before placing the sample vessel on the weighing pan. This way, ionizing is
active while placing the sample vessel on the weighing pan and electric charges are neutralized. In addition, try
not to touch the upper edge of the sample vessel, e.g., close to a vial opening, when handling it.

If the problem persists, try increasing the humidity in the weighing chamber.
