7. CALIBRATION
This function adjusts the scale (indicator) for accurate weighing.
Calibration must be done when the FS-D is initially connected to a load cell (base unit).
Calibration may also be required according the changes in the environment.
When the scale (indicator) has been moved.
When the ambient environment has
significantly changed.
For regular calibration.
Loose the lock screws on the rear side of the
display pod, and remove the (CAL) switch
cover. The calibration switch inside.
7-1. Calibration using a weight
1. Warm up the indicator with a weighing platform connected for at least half an hour.
Change the user function setting “f01” or place something on the platform to
disable the auto power-off function.
When turning the power on and the indicator may display ------- ,
press the
PRINT/ENT
key to proceed to the weighing mode.
2. Press and hold the calibration (CAL) switch until
Cal
appears, and release the switch.
Press and hold the
0
key for about 5 seconds, then you
can also enter the calibration mode
(when “C01-0” is set).
Press the
ON/OFF
key or (CAL) switch to exit without
calibration.
3. Press the
PRINT/ENT
key, then the gravity
acceleration value will be displayed.
It is not necessary to set the gravity acceleration value
when calibrating the indicator with a calibration weight
at the place where it is to be used. (See the next
section about the gravity acceleration correction.)
4. Press the
PRINT/ENT
key, then
Cal
0
will be
displayed.
5. Make sure that there is nothing on the platform, and wait
until the STABLE indicator turns on.
6. Press the
PRINT/ENT
key. The indicator inputs the
zero point, and the display shows
5pn 1
and the
weight value for calibration (SPAN calibration).
The weight value is equal to the capacity. When you
enter with “kg” or “g” mode, then the value is “kg”.
Entering with “lb” or “oz”, then “lb”.
