- Although this is a fundamentally sound conjecture, we have not tried it because the support for the Mettler pan is grounded and not easily insulated.
- Normal balance room humidity by itself is also ineffective in dissipating static charges on these filters. The measurements described here were made at 30% RH, but earlier charge effects had been measured at 50-65 % RH.
- At least one manufacturer, Mettler-Toledo, sells pan accessories designed to eliminate the static charge problem. These consist of two large-diameter pans, a large draft shield, and a support bracket that allows both pans to be grounded.

- These measurements were made in a motel room during a field study. The room air conditioner was left off until needed, whereupon weighing was halted until the room cooled and it could be turned off once again.
