5.2.3. Zero Calibration
Procedure
Step 8 Check the Cal 0 display.
Select a zero calibration method to adjust the zero point
Weighing input
(Normal way)
The adjustment method
with nothing on the
weighing unit.
To step 9
Digital input
The numerical way to
input a load cell output
voltage.
To step 10
Weighing Input
Step 9 Place nothing on the weighing unit. Press the ENTER
key after the STABLE mark has turned ON. The new
zero point parameter will be stored. Proceed to step11.
ESC key .......... The key not to change the zero point
data and proceed to the next step.
Caution Do not press the ENTER key while the STABLE
mark is off (detecting motion). Arrange the
condition using the F00 filter function.
Digital Input
Step10 Pressing the +/- key, a stored input voltage parameter
of the zero point is displayed in the unit of mV/V. Adjust
the input voltage using the 0 - 9 keys.
ENTER ....... The key to store the zero point parameter
and proceed to the next step.
ESC k ey..... The key to proceed to the next step without
changing the parameter.
5.2.4. Span Calibration
Step11 Check the capacity display after Cal f is displayed for 2 seconds.
Select a span calibration method to adjust the capacity.
Weighing a mass less than the
maximum capacity The method to weigh a mass less
than the maximum capacity.
To step 12
Weighing maximum capacity
mass The method to weigh a mass
equivalent to the maximum capacity.
To step 14
Digital input
The numerical way to enter a load
cell output voltage.
To step 16
