Chapter 1. Product Overview

1.1 Machine Outline

• The base of software used is the same as that of the IGB and IGX Series. Therefore, the Setup and

Test mode items are same as those of the IGB and IGX Series. The machine functions are available
within these standard specifications.

• A check function of the upper and lower weight limits are standardly provided with the IGB and IGX

Series.

• The main board is different from that of the IGB and IGX Series. However, basic operations are same

for these models.

• For the IGB Series, an LCD is adopted, and either two dry batteries or an AC adapter can be used as a

power source.

• For the IGX Series, a VFD is adopted, and a wide selection of power sources ranging from 100 VAC to

240 VAC is available.

1. By setting the country code, weighing conditions will function based on the default data from

Note

address 112 to 115.

2. The data is set to meet certified conditions for each country, so there is no need to change the
data.

3. Position “A” indicates the upper position of one-byte data, and “B” indicates the lower position.

4. As for Weight, a function is selected with “1”, “2”, “4”, and “8” in bit unit, and “H” indicates
Hexadecimal data.

5. Individual setting value “99” cannot be entered. (Displayed only when settings are changed in C7
mode)

6. “USA 2” code is settings to allow changing between “lb” and “kg” at anytime even in cases other
than a stable condition at zero point. (“USA 1” can change between “lb” and “kg” only when the
condition is stabilized at zero point)

When using this function, a maximum of 0.2e error may occur in weighing immediately after the

change. This error is calibrated by zero point adjustment (or zero tracking), and an accurate
weighing is guaranteed.
When selecting the weighing capacity exclusively for either “lb” or “kg”, use “USA 1”.

2.2.3 Operation Procedure

Operation Display

1. Starting Test Mode (C1)

 Press ON/OFF.
 Press and hold ZERO(+) while all segments are lit.
 Press SET.

2. Setting Country Number

 To increase the number, press ZERO(+).
 To decrease the number, press TARE(-).
 Press SET.

[Example] Asia = 3

3. Setting Scale Number

 When setting “60kg”, select “08”.
 Press SET.

4. Selecting Weight at Span Adjustment
The following weight can be selected:

kg: 1/1.0→1/2.0→1/2.5→1/5.0 of weighing capacity
lb: 1/1.0→1/2.0→1/2.5→1/5.0 of weighing capacity

・ Pressing ZERO(+) selects the next item in the above

sequence, and pressing TARE(-) selects the previous item.

kg unit: Same weight is used as weighing

capacity.

[Example] Selecting “kg” unit and “1/2.0” for weighing

capacity “150kg” will require the total 75kg
weight.

To change between “lb” and “kg”, press ZERO(+) and

TARE(-) at the same time.

5. Zero Point Adjustment

After selecting the weight amount, ensure that nothing is
placed on the weighing platter, then press SET.

The previously set zero point A/D data will be displayed.
Zero point indicator W will light up.

Press ZERO(+) to set “20000” counts forcibly.

Zero point indicator W will go off.

kg unit: Half weight is used of weighing

capacity.

lb unit: Same weight is used as weighing

capacity.

Operation Display

6. Span Adjustment

Place the selected weight on the weighing platter, then press

TARE(-).

[Example] 60kg Scale: Weight selection: “kg” unit and “1/1”

Place a 60kg weight, 30000 + Zero point 20000 =

50000 counts

In case of “kg” unit “1/2” for a weight selection, place

a 30kg weight, then 15000 + Zero point 20000 =
35000 counts

・ One graduation equals 5 counts.

Processing is automatically executed in the following order:

[Calib] (Calibration) Computing process executing
[C- OK] (Calibration OK) Computing result succeeded

[No. of adjusted counts] Computing result

[C-Err] will be displayed, indicating a computing result error
when span adjustment is performed without placing a weight.

Place a weight and press TARE(-).

7. Saving Data

To save Country No., Scale No., Zero point, and Span data in
E2ROM.

・ Remove the weight from the weighing platter.
・ Remove the seal covering the opening on the rear case of

display unit.

・ Insert a thin rod such as the inner shaft of a ball-point pen

into the hole, and push the Memory Switch located on the
main board.

When writing has finished normally, [S-OK] will be

displayed.

・ To release the above status, press COLUMN.

1. E2ROM data is garbled.

• Check the voltage of the main

power outlet.

• Check the power cable, and replace

if necessary.

• Check the FUSE (1A 250V)

• Check the TRANS ASSY

• Check the main board PS-016

connector XJ2.

• Check batteries, and replace if

necessary.

• When using the AC adapter, confirm

that the adapter voltage is within the
range of 3.2 to 6VDC.

• Using the tester, check that the key

is conducting, and replace if
necessary.

• Replace the main board PS-016
