5. CALIBRATION
What is Calibration?
This is to match the displayed numerical value and the actual weight value for displaying
weight.
5-1. ZERO CALIBRATION
“0” is a point to be a standard for displaying weight of indicator.
Please carry out Zero Calibration so that “0”can be displayed when all the mechanism is
fixed on the weight sensor load-cell. (Early load offsetting of Load-Cell)
5-2. SPAN CALIBRATION
This is to set the linearity so that display value from “0” to maximum weight and the actual
weight can be matched for displaying the weight of indicator.
▶ TO ENTER SPAN CALIBRATION
While pressing "3" KEY, please turn the power ON. Then, TEST will be shown at display.
At this stage, please press “3” Key again and then SET.CAL will be displayed.
Press ENTER Key and then d__XX will be shown at display.
▶ When Power is OFF
① While pressing"3" KEY, turn the power ON – TEST displayed.
② Press “3” Key - SET.CAL. displayed.
③ Press ENTER Key – “d__XX”
▶ How to carry out SPAN CALIBRATION
There are 5 steps for Span Calibration. Each step will be carried out by Enter key. Please
use Clear Key to return to previous step.
Î Move to next step: Use ENTER Key
Î Return to previous step: Use CLEAR Key

Ⅰ. STEP 1
This step is to set the value of 1 division. (Unit of minimum display division)
Here, “d” stands for Division and it indicates “the value of 1 division
(Minimum division display)”
This value change is shown in order of “01-02-05-10-20-50” each time 0 Key
is pressed. After it stopped at a desired value – a certain value of 1 division,
press ENTER Key so that the value can be memorized as “the value of one
division” and then move to the next step.
Ⅱ. STEP 2
This step is to set the maximum display capacity.
Here, “CAPA” stands for Capacity and it indicates the maximum display capacity
that can be weighed by scale. You should input your desired maximum display
capacity value instead of an optional numerical value currently displayed.
To input, please input the number you want by using the number Key on Key
Board and then press ENTER Key so that the current value will be memorized
and move to the next step.
Î Please do not set (Value of 1 division/MAX display capacity) to be over (1/20,000)
When it is over (1/20,000), Error message will be displayed. You can use up to 1/20,000 only.
Ⅲ. STEP 3
This step is to confirm the current “0” status of scale.
After you check the currently displayed value, please press “ENTER” Key.
And then the gauge bar will goes up for about 3 seconds.
You will move to the next step automatically.
Ⅳ. STEP 4
SPAN” will be shown on capacity display and then it will be changed to
“CAPA” value which is the value in STEP 2.
If standard span weight of CAPA is not ready here, please prepare for a span
standard weight that is over 10% of CAPA value and then input the value by
using numerical Key and then press “ENTER” Key so that you can move to the
next step.
At this stage, “UP” means you have to put the prepared span standard weight
on scale.
After you put on the span standard weight on scale and when the capacity is
stable enough without any impact or vibration, please press “ENTER” KEY so
that Gauge bar can go up for about 3 seconds and you can move to the next
step.

Ⅴ. STEP 5
This span is to display the calculated Span constant.
If indicator displays this condition, it means Span calculation is finished.
If constant value is between 0.50000~1.50000, span is normally calibrated.
If constant value is not between 0.50000~1.50000, you need to do the Span
calibration once again so that you can use the scale with better accuracy.
After span constant is displayed, C_End._ will be displayed and slowly
flashing for about 3 seconds to test the condition of display. Then it will
be displayed as “normal operation mode” for measuring.
Now, Span Calibration is completed.
→ When you do setting weight:
When (Value of one division/Max. display capacity) less than 1/5,000,
you need to prepare for a standard weight that is over 10% of Max display division
and then set the value. When it is more than 1/5,000, you need to prepare for a standard
weight that is over 20% of Max display division and then set the value. This is to do the span
calibration with better accuracy.
- If you do the setting a weight over Max display division, an Error Message
“Err 04” will be displayed.
- If you do the setting a weight below 10 % of Max display division,
an Error Message “Error 05” will be displayed.
