This screen allows you to re-range the outputs of your instrument. You may select
any full-scale value between 100% and 50% of the displayed maximum value (this
is the factory full-scale calibration value).
The new full-scale value that you select will re-define the analog outputs of the
instrument. The 20 mA signal and the corresponding voltage signal (5 VDC, 1-5
VDC or 10 VDC) will now represent this new full-scale value.
Caution: Changing the full-scale value of the instrument does not affect the
accuracy.
The accuracy is always
±
1% of the original factory full-scale calibration value.
Caution: For any instrument, if a value greater than the factory full scale
calibration value is entered on this screen, the Smart-Trak 2 will modify the
requested value to equal the factory full scale calibration value.
If you choose to change the full-scale value, press the enter key. The first digit will
blink. Use the up and down arrows to adjust the value of the digit or the left and
right arrows to choose another digit. When you have completed your modification,
press the enter key. The display will show:
