4) Make sure that there is no load on the platform and then press the
ZERO
key to zero the value.
5) Press the
NET/GROSS
key to save the zero point value into memory.
6) The display will show "EndC0" momentarily, then return to "F 16". Now scroll to keyword F17
to complete the span calibration.
To Calibrate the Span
1) While in the
System Keyword Setup Mode
, scroll to keyword F17.
2) At keyword F17, scroll down once, using the
ZERO
key. The display will momentarily show "C
1" followed by a value with one flashing digit. This value will be zero with the decimal point set
to the value set in keyword F10. Place test weights on the platform equalling full scale capacity.
3) Use the keypad (see
Figure 2
on page 4) to adjust the displayed value to the test weight value.
Increase the flashing digit by pressing the
lb/kg
key. Decrease the flashing digit by pressing
the
ZERO
key. The position of the flashing digit is changed by either the
key or the
TARE
key.
4) After the value is set, press the
NET/GROSS
key to save the value.
5) If the procedure was a success, the display will show "EndC1" momentarily, and then revert to
"F 17". Please record the calibration value at this time for future use.
6) If the calibration was not successful, an error message will appear on the display. Take the
shown action to correct the error and then recalibrate the system.
"Err0"- The calibration test weight or the adjusted keyed-in weight is larger than the
full capacity of the scale. Change the test weight or check the input data.
"Err1"- The calibration test weight or the adjusted keyed-in weight is smaller than
1% of the full capacity of the scale. Change the test weight or input data.
"Err2"- The internal resolution of the scale is not high enough to accept the calibra-
tion value. Select a larger parameter for the span gain.
To Record the Calibration Values through the F18 Keyword
Please note that the values displayed from this keyword are only valid after a successful calibra-
tion has been performed.
1) While in the System Keyword Setup Mode, scroll to keyword F18.
2) At keyword F18, scroll down once, using the
ZERO
key to enter the View Calibration menu.
