ibalance Manual & Calibration guide


This manual covers installation, operation and troubleshooting for the iBalance 201. To ensure proper operation of the balance , please read this manual completely .


The iBalance 201 portable advanced balance is a precision weighing instrument, designed to provide years of service with virtually no maintenance .The Portable Advanced housing is constructed of a material which is impact resistant.contains a one piece solid-state precision electronics PC board.and a five digit LCD display which is 0.5 inches in height.All Portable Advanced balances are initially factory set to measure in grams and can be set to measure in other units of measure as desired. Each balance operates through a series of menus which enable precise calibration and the selection of various parameters which enhance operation. A built in lock switch prevents calibration settings from being changed. Power is supplied through an AC adapter or batteries.

3. This Portable Advanced balance contains two display menus which enable you to calibrate and configure the balance for specific operating requirements.

· CALIBRATION Menu–Allows the balance to be calibrated by using standard weights.

· SETUP Menu–allows the balance to be set for environmental conditions and customized for specific weighing functions.

When the balance is first turned on, it can be used to weigh in grams tare items without setting the menus. Refer to the individual menus in this manual for detailed descriptions and procedures for programming.


All ibalances are supplied with a weighing platform, AC power adapter, instruction manual, and certificate of quality.



Balance performance can be affected by excessive air currents, corrosives, vibration, temperature changes or humidity extremes.

5.1 DO NOT use the balance:

· Near open windows or doors causing drafts or rapid temperature changes.

· Near air conditioning or heat vents.

· Near vibrating, rotating or reciprocating equipment.

8.6.1 Custom Unit Conversion Factor

When you need to display

weight measurements in a weighing

unit Other than those provided

standard with the balance, this

feature can be used to create your

own custom weighing unit. It

permits you to enter a conversion

factor which the balance will use

to convert grams to the desired

unit of measure.

One example is shown at the

end of this section. It illustrates

how to set the conversion factors to

display weight in Grains.

Conversion Weight Weight

Factor × in = in

Grams custom unit(s)

Conversion factors are expressed in scientific notation and entered into the balance in three parts:

· A number between 0 and 9 to four decimal places.

· A power of 10 called the exponent.

· A least significant digit (LSD).

Use the following procedure to enter conversion factors :

? Access the C. Unit submenu.

? The mantissa of the current conversion factor will be displayed. This will


be a number between 0 and 9.9999 with the first digit flashing. For conversion factors outside of this range, the exponent will be used to FLASHING

move the decimal point.

? Press to change the value

of the first digit.

? When the desired value is FLASHING

displayed, press to accept it and

the nest digit will begin flashing.

? Set the value of all digits in

the same manner.

? After the last digit is entered,

the display will show the current

exponent. The exponent is shown on

the display preceded by the letter E.

There are 7 exponent values which

you can choose from (see table).

? Press to change the


? Press to accept the

displayed exponent. When is

released, the display will show the

current least significant digit.

The least significant digit is the digit in

the last decimal place on the display.

The selection you make causes the

balance to count by 1’s, 2’s or 5’s

in this position. There are 7 LSD

settings you can choose from (see


? Press to change the LSD.


? Press to accept the displayed LSD. When is released,

C. Unit will be displayed again and the Setup menu will be returned.

? Proceed to the next item on the Setup menu or use END to exit the Setup menu and save your selections.

8.6.2 (example) Converting to "Grains"

? Determine the number of

grains equal to one gram :

IF 1 grain = 0.0647989 grams

THEN 1 gram = 1 / 0.0647989

? Since the balance displays only 5 OR 1 gram = 15.43236 grains digits, round the number to the 5 most

significant digits :

? Using this number, enter the

conversion factor : "15432"

The display will indicate 1 unit for Number = 1.5432

every grain placed on the platform. E = 1 (to move the decimal point

one place to the right)

d = 1 (normal setting )

8.7 Averaging Level

Averaging level compensates for vibration or excessive air currents. During operation, the balance continually takes weight readings from the weighing cell. Successive readings are then digitally processed to achieve a stabilized display. Use this submenu to specify how much processing you need to obtain stable results.
