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 
enter 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 a 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
