14.2. Sensitivity Adjustment Using a Weight
Sensitivity adjustment must be done using a weight when the scale is used for the first time or when
moving it to a different location. If you cannot obtain a sensitivity adjustment weight, the scale can
be adjusted by correcting for gravitational acceleration. Refer to the gravitational acceleration map
at the end of this document to change the gravitational acceleration value saved on the scale to
that for the location where it is installed.
Note: Prepare a weight. (A weight equivalent to the weighing capacity of the scale to be
adjustd is recommended. However, the value for the weight can be set (changed).)
1. Turn on the scale and supply it with power for 30 minutes or longer.
□
Change the parameter for the function table item
poff
or
place something on the weighing pan to prevent the automatic
power off function from activating.
2. Refer to “
14.1. Sensitivity Adjustment Items
”.
Cal
is
displayed when you enter sensitivity adjustment mode.
3. Press the TARE key to display
Cal 0
. Make sure
there is nothing on the weighing pan and wait for the
stability indicator to light up.
4. Press the TARE key to save the zero point on the
scale and display the value for the weight.
□
The value for the weight is the same as the weighing
capacity. (Initial state)
□
To adjust just the zero point, turn off the scale to end
without performing step 5.
5. To adjust with a weight value different than the weighing
capacity, change the value with the keys below.
□
A weight equivalent to the weighing capacity of the scale is
ordinarily used. If using a different weight, it should be at
least 2/3 the weighing capacity.
6. Place a weight of the displayed value on the weighing pan. Wait for the stability indicator to
light up.
7. Press the TARE key to end sensitivity adjustment.
“
end
”
will be displayed.
To end setting, press the ZERO key or CAL switch. This will return you to weighing mode.
8. Place a weight on the weighing pan again to check if it is within the set value
±0.01g/0.02g/0.04g(FG-30KCMWP/ FG-60KCLWP/ FG-150KCLWP). If it is not within the
range, start over from the first step of this procedure in the appropriate ambient conditions.
Note: If the scale is moved to a distant location after sensitivity adjustment, adjust the
gravitational acceleration value to that of the area where it will be adjusted next.
Then adjust the scale. See the next chapter for setting gravitational acceleration.
