INDICATOR CALIBRATION
Calibration Overview
You will be calibrating an actual load sensor to the indicator using live test loads. You can have
up to three span calibration points, denoted as C1 through C3. The value of each subsequent
calibration point should be higher than the last, e.g., the C2 value should be greater than the C1
value, etc.
The calibration procedure comprises two steps: zero calibration (F16) and span calibration
(F17). We recommend doing zero calibration (F16) first.
Zero Calibration Instructions (F16)
1. While in the Setup mode, scroll to "F 16", and then scroll down once using the
ZERO (down) key. The display will momentarily show "2Ero" followed by a value. This
value is the internal A/D count and can prove useful when trying to troubleshoot setup
problems.
2. Assure a no-load condition on the scale platform and then press the ZERO key again to
zero the display reading. Do NOT skip this step!
3. Press the MODE (set) key to save the zero-point value. The display will show “SEt” and
"EndC0" momentarily, and then revert up to F16.
Span Calibration Instructions (F17)
1. While in the Setup mode, scroll to "F 17", and then scroll down once using the ZERO
(down) key. The indicator will briefly display ‘C 1’ and then prompt you to enter the data
for the span calibration point (C1).
2. Place the actual calibration load (weights) onto the scale platform.
3. Use the numeric keys to key-in the actual test weight value. There is no need to enter a
decimal point since it is fixed on the display. If you make a mistake, use the C/CE key as
a backspace key.
4. Press the MODE (set) key to save the value. The indicator briefly displays ‘SEt’ and then
moves to the next calibration point (C2).
5. Repeat steps 2 through 4 to enter data for the remainder of the calibration points. You
need not enter data for all three calibration points. To cease entering additional
calibration points, simply enter zero for the new value, e.g., 0.0 lb.
6. At the conclusion of C3 (or the last calibration point), the indicator will revert up to “F17”.
