NSTRUMENTS
TGA 2050 3–9
Automatic Tare
Because the TGA 2050 has two weight ranges,
taring is done for both ranges. The tare weight is
stored by the instrument for both weight ranges.
1. Place the empty sample pan on the sample
platform.
2. Press the TARE key on the instrument
keypad or from the controller. The TGA will
automatically load the pan, raise the furnace
(to protect the pan from air currents), weigh
the pan, store the weight as the offset for
each weight range, and unload the pan.
Manual Tare
Manual tare operates in the weight range
indicated, by storing the current reading as an
offset, and estimates the tare weight for the other
weight range (typically the 1-gm range). The
estimate is accurate if the TGA 2050 has been
tared or weight-calibrated recently.
1. Place the empty sample pan on the sample
platform.
2. Press the LOAD key to load the pan onto the
balance.
3. Press the FURNACE key to close the
furnace, to protect the pan from air currents.
4. Observe the weight reading on the
controller's Signal Display window screen
(Signal A Weight).
5. Wait for the Signal A Weight to stabilize,
and then choose Auto Zero to store the
displayed weight as the offset.
6. Press the UNLOAD key to open the furnace
and unload the pan.
