The total mechanical
capacity of the balance is
5 gm. In order to avoid
damaging the balance
assembly, never allow the
total weight of the sample,
tare weight, hang-down
wires, and pans to exceed
5 gm.

The TGA balance mechanism is sensitive
to changes in the surrounding room tempera-
ture. For optimum accuracy, you must
regulate the ambient temperature.
