1.Introduction
■Introduction
This product as an indicator for weighing instruction and control is designed for the most
suitable use of any meters (packer, weigh separator, platform scale, various tensile and
compression test equipment)that can be applied in the widest way throughout industries.
This product ensures communications with external devices such as computers as it basically
installs an RS-232C port.
In addition, this product can be conveniently used for the weighing control as it basically has
three relay outputs necessary for control (applicableonly if there is relay out).
Please utilize all the functions in this product sufficiently as you can use the device properly
with good knowledge of this manual before you use this product.

7. Set-up
■Set-up
- Overview
It means the setting works to ensure the indicator to be operated under the optimal conditions by
settingF-FUNCTIONproperlytotheoperatingdevicesandsurroundingenvironment.
- How to enter Set-up
“TEST” is displayed when the power is turned on while any key is being pressed.
At this time, press Key to display ST.CAL on the main display.
At this state, press Key to display 01-XX.
EX) While the power is turned off;
①Press "3" Key and turn on the power for “TEST___”
②Press "3" Key for “SET. CAL”
③Press “CLEAR” Key for “F01-XX”
“Χ” is a random number.
- How to change the unique number for F-FUNCTION
To change the unique number for F-Function, the unique number increases whenever
Key is pressed once.
It increases to 01-53 and then returns to 01.
Whenever Key is pressed, the number increases in 0 -> 9.
Whenever key is pressed, it moves to the left.
Press Keytocallthefunction afterthenumberisassigned tothe

- How to enter after assigning F-Function
After assigning F-Function using & Key, you may enter the
appropriate F-Function using Key.
1.Whenever Key is pressed, the number increases in 0~9 on the position.
2.Press Key to change the number in 0~9.
3. Press Key again to increase the number in 0~9.
4. Press Keyto enter theassigned F-Function.
EX) Assign F53andthen enter it:
1. On thescreen for F01-01
2.When the number 1 is blinking, press Key to make the number 3.
3. Press Key to move the number on the position and then the number 0 is blinking.
4. Press Key again to make the number 5.
5. Press Keyagain to entertheFunction immediately.
※Caution:Beawarethat thevaluefor the Function isstored when Keyispressed.
- How to change the setting of F-Function
After entering a value to change the setting of F-Function, press Key to
store it in the internal memory and finish the change.
If Key is not pressed only after the desired value is entered, the value is not
stored.
※Thevalue canbe storedinthe internal memorywhen you press
Key afterthevalueis changed to your desired set value.
