Ⅴ. Step 5
A span constant is shown on the display
It enters the weight mode as C.EnD. is
blinking and then reset.
※ 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.

■ Error Display Status and Measures in Detail
The maximum display division /
the value of a division is 20,000
or more.
Enter again the maximum display
division / the value of a division to
become 20,000 or less
The setting of standard
counterweights is set to more
than the maximum display
division.
Enter again the setting of standard
counterweights to become less than
the maximum display division.
The setting of standard
counterweights is set to 10% or
less of the maximum display
division.
Enter again the setting of standard
counterweights to become 10% or
more of the division.
The output value for the load cell
is too large.
Check if the weight is loaded as
much as it is set with the standard
counterweights. If the standard
counterweights greater than the
setting value are loaded, set them to
the setting value.
The output value for the load cell
is too small.
Check if the weight is loaded as
much as it is set with the standard
counterweights. If the standard
counterweights smaller than the
setting value are loaded, set them to
the setting value.
Calibration judgment cannot be
done due to the continuous
shaking on the weight.
Check out the surrounding
environment and separate any
vibrating source for the stable
weighing while preventing the
indicator from any great vibration.
- Check out any defect in the load
cell
- Check out any electric leak in the
connecting wire to the load cell.
- Check out the insulation resistance
in the load cell.
A value that should not be
entered to F-Function is entered.
Check out the value and enter the
proper value again.
When a constant Y.YXXXX YY is
a value between 3.9~9.9 > the
resolving power is 1/20000 and
small counterweights are placed.
Lower the resolving power.
(Ex: value for a division 1 -> 5)

■ F-FUNCTION DESCRIPTIONS IN DETAIL
(● : Factory Default)
* 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.
Motion Band Range Setting
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.

Zero Tracking Adjustment Range Setting
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.
Auto – Zero Range Setting
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).
More vibration
↑
Less vibration
More Sensitive
Less Sensitive
* This function should be used after the adjustment for the set value depending on the environment
(surrounding vibration).
* Decrease the set value for the quicker response speed in the indicator
ZERO, TARE Key Operation Mode
“ZERO” Key can be operated only if the weight is stabilized.
“ZERO” Key can be operated even if there is any change in the
weight.
If there is weight change within 250g within 0.75 SEC,
the indicator automatically displays 0.
The changed value is shown if there
was any greater change than 250g
within 0.75SEC

ZERO Key Range Setting Mode
Operations within 2% of maximum CAPA
Operations within 5% of maximum CAPA
Operations within 10% of maximum CAPA
Operations within 20% of maximum CAPA
Operations within 100% of maximum CAPA
* As the indicator set 10% more for its allowable range, the maximum weight in reality becomes
110kg on the indicator if the maximum weight is set to 100kg.
Ex) If the maximum weight (CAPA) is set to 100kg and F08 to “T”, then “ZERO” Key can be
operated within 1kg (10%).
Setting Mode for TARE Key Operating Range
Operations within 10% of maximum CAPA
Operations within 20% of maximum CAPA
Operations within 50% of maximum CAPA
Operations within 100% of maximum CAPA
Ex) “Tare” Key can be operated within 50kg when the maximum weight (CAPA) is set to 100kg and
F09 to “2”.
Hold (once) to detect the maximum weight (Peak-Hold)

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
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.
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
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.
Equivalent Input Confirmation and Setting
Equivalent input can be confirmed and modified.
Calibration Span Constant Confirmation
Set the number to 89 using “ZERO” and “TARE” Key in F-Function Mode and press
“SET” Key to show span constant on the display.

※ 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.

- F-83 (Parts related to the analog output)
Set Max. Analog Output Value
Maximum analog output of 0 ~ 10V, 4 ~ 20mA can be set.
Ex) If 1000 is set, the output of 10V or 20mA is done when the weight value reaches
1000.
- While Key Test Mode in TEST2 in relation with the analog setting;
press Key for the output of 4mA(or 0V).
press Key for the output of 12mA(or 5V).
press Key for the output of 20mA(or 10V).
press Key to move to Test. (EXIT)
