TT-830 Bench Scale Service Manual
You may use as little as 1% of
full capacity to span the system
but Weigh-Tronix recommends
using as close to 100% of full
capacity as possible.
SPAN If you press the SPAN soft key, follow these instructions:
1. The current span calibration
weight is displayed. Press
ENTER to accept this weight or
key in a new one and press
ENTER . . . The display prompts you to apply the
test weight load to the scale.
2. Apply the test weight load to the
scale and press
ENTER . . . The indicator determines the span
and tells you when it is done. Above
the text, the display should show you
the correct test weight. If not perform
the span again.
3. Press any key to return to the
CALIBRATE display.
The soft key group and functions accessed by the MORE soft key are
explained on the previous page.
As you try to exit the calibration section the display will ask if you want any
changes saved. Press the
YES key if you want changes saved, NO if you do
not.
This concludes the calibration section of the manual.
There is one more menu that you can access for testing purposes. Hold the
ESCAPE key for 5 seconds then key in 911 at the prompt. These softkeys
appear:

tion.
