General Weight Calibration Mode (CAL 1 Mode)
I. Step 1
It is a step to set the value of a division (minimum division of a scale to be displayed).
In this, it is an abbreviation of division meaning “the
value for a division of a scale (minimum division of a
scale to
be displayed)”.
Whenever Key is pressed, the value increases in the order of “01 -> 02 -> 05 -> 10 -> 20 -> 50”.
Whenever Key is pressed, the value decreases in the reverse order of the above values.
Press Key to escape from ST.CAL.
Press Key to remember “the value for a division” and then move to the next step.
. Step 2
It is a step to set the maximum display weight
In this, “CAPA” is an abbreviation, which means
the maximum display weight that can be weighted
in the indicator. Enter the maximum display weight as the user desire instead of a random value that is currently displayed.
Whenever Key is pressed, the number increases in 0 -> 9
Whenever Key is pressed, it moves to the left Press Key to move the setting of a division value
Press Key to store the currently designated value to the maximum display weight. Move on the next step.
Do not set (a value for a division of a scale/maximum display weight) to more than (1/30,000). More than
(1/30,000) cannot be set. The product can be applied to at maximum 1/30,000.

Press Key to store the currently displayed
zeroing value. Move on to the next step.
. Step 4
It is a step to load the prepared standard counterweights on the indicator.
In this, prepare standard counterweights for
10% or more of the maximum weight (CAPA)
Whenever Key is pressed, the number increases in
0 -> 9
Whenever Key is pressed, it moves to the left Press Key to check zero status and move Press Key to store the currently displayed value for

While setting the weight of counterweights;
The span can be more accurately adjusted; if (a value for a division) is 1/5,000 or less, prepare counterweights in 10% or more of the maximum display division and set the value; if it is 1/5,000 or more, prepare counterweights in 20% or more of the maximum display division and set the value.
- If the weight of counterweights for not less than the maximum display division is set, Error 04 Message is displayed.
- If the weight of counterweights for 10% or less of the maximum display division is set, Error 05 Message is displayed.

* The weight on the indicator is not stored in the Normal Mode during any blackout or power-off.
Accordingly, the power should be turned on after the weighing object is removed from the indicator. * “0” is immediately shown on the display in the Back-up Mode by reading the stored zero point when the power is turned on. Therefore, the weight is shown during any blackout or power-off if there is any weighing object on the indicator if the power is turned on.

9
A function to set how much the range of variations for weight per hour is set for the stable status. 0 : With less vibration (weak) ~ 3: With more vibration (strong)
* It is a function to stabilize the state when the range of variations for weight in the set time does not go over the A/D Count set range. There are subtle vibrations in general when a weighing object is placed on the indicator.
Hence, the state indicator “Stable” is turned on the display once the vibration is stabilized. “Motion Band” sets the time range to stabilize the vibration in this way.

The automatic zero calibration if it does not exceed a certain range of divisions within a certain time if there is any subtle change in the weight for some reason (environment, temperature, wind, dust, etc.)
Ex) F04 is set to “3” when the maximum display division is set to 120.00Kg and a division to 0.05Kg;
This function prevents the indicator from any impact from the accumulated dusts or dirt where you might have a lot of dusts or dirt in the environment during the use.

A function to return the display value to “0” immediately
once the weight is displayed and stabilized under the set value.
* The automatic zeroing can be done (before the weighing is done again) if there is any remaining under the set value with no use of „ZERO‟ Key once this function is set. * Ex) If the maximum display weight is set to 120.00Kg, a division to 0.02Kg and F05 to 30 in the
indicator, the display value becomes “0.00Kg” as the zeroing is immediately operated once
(STEADY LAMP ON) is carried while the remaining amount exists up to ±(0.02~0.30Kg).

Range near zero to check the emptiness of the indicator Ex) 000 : Near Zero Relay is operated when the display of weight is “0”. 010 : Near Zero Relay is operated when the display of weight is “10” or less. 150 : Near Zero Relay is operated when the display of weight is “150” or less.
Zero Display Range Setting
F81
XXXXXX
A function to set the display range of zero. Ex) If 50 is set, any value not less than the value is all shown with 0 on the display.
Zero Minus Value Setting
F82
If a value is set to F82, the value minus the value set to zero is displayed.
Ex) if 1000 is set, the zero value displayed in TEST1 Mode, for example, the value of 6000 is shown as 5000 after 1000 is deducted from the value.
Maximum Analog Output Setting
F83
Maximum analog output of 0 ~ 10V, 4 ~ 20mA can be set.
Ex) If 1000 is set, 10V or 20mA output is done when the weight reaches 1000.

RS-422/485 Serial Communication (Separate Option)
RS-422/485 method is more stable for electric noises than any other communication methods as it communicate signals in the voltage difference. In addition, the wiring should be done away from AC power cable or other electric wires. The shield coax cable should be used in any case. The recommended distance in use is the dedicated line within 1.2km.

Reference Although any of the signal level conversion methods as stated above is used, there are
many cases with problems occurring from the fact that the power supply (the grounding line to be exact) for the transmission side is connected from a remote distance connection through the communication line. Noises flown in through this grounding line might lead the transmitting or receiving system to the instability. For such reasons, it is desirable to insulate and separate the power supply for the system from the power supply for communication line if it involves a long-distant transmission or it is used under the surrounding environment with many noises to the communication system.
