SYSTEM CALIBRATION
Calibration Overview
Digital system calibration is accomplished in two steps: zero calibration (F16) and span calibra-
tion (F17). You may restore factory calibration values via the B6 menu.
In the unlikely event that any calibration value is lost, the setup menu makes provisions for re-
entering these values via F19 and F20; thus eliminating the need for re-calibration with test
weights.
For dual wireless A/D modules systems (e.g. TI-500 RFTM-2BE), a digital corner calibration fea-
ture is also available. It does not require a specific test weight value, but the maximum weight
that should be used is approximately 25% of the rated capacity of the platform.
NOTE
: Please perform corner calibration prior to executing zero/span calibration.
Digital Corner Calibration (dual wireless units only)
1. Switch off the RF digital indicator by pressing and holding the ZERO/OFF key for about 5
seconds.
2. Press and hold down the ON/PRINT key (about 20 seconds) until the screen shows “-F-”.
3. Press the ON/PRINT key until the screen displays “-B-”.
4. Scroll down once using the ZERO/OFF key to enter the “Bluetooth” menu. Scale shows
“B 1”.
5. While in the Bluetooth Setup mode, scroll to "
B 10
", and then scroll down once using the
ZERO/OFF key to enter corner calibration menu. The indicator will display a value. This val-
ue is the internal A/D count and can prove useful when trying to troubleshoot setup prob-
lems.
6. Remove all items from the weighing platform.
7. Press the NET/GROSS key to save the zero point value. The display will show "
Corn-1
".
8. Place the test weight on the load cell/corner #1 of the weighing platform.
9. Wait 2-3 seconds to allow the internal reading to stabilize.
10. Press the NET/GROSS key to save the load cell/corner #1 calibration. The display will show
"
Corn-2
".
11. Repeat steps 8-10 for the remaining load cells/corners. At the conclusion of corner #4 cali-
bration, the display will show "
Set--
".
12. Press the NET/GROSS key to finish the corner calibration and revert back up to B10.
13. In order to save all parameter settings, it is imperative to exit all menus in the following
manner: At the parameter level, press the UNITS (up) key twice (two times) to exit the
Bluetooth Menu. The indicator displays ‘SAvE’ and then automatically powers off.
