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.
