ELECTRONIC BALANCE
INSTRUCTION MANUAL
Low Batteries & Faulty AC Adaptors are the #1 cause of scale malfunction and
inaccuracy!
We test all of our scale returns from consumers. Fully 60% of consumer
returns are simply dead or low batteries. This sounds silly but it's true! A scale will perform
slowly, or read inaccurately when it has low batteries. Please replace the batteries often (and
only use good quality batteries). We include good quality batteries with all of our scales but
batteries can run low in storage. A Faulty AC adaptor can cause your scale to act unstable
with numbers "jumping" all around. Please test your scale with a good set of batteries
(instead of the AC adaptor) to determine if perhaps the AC adaptor is faulty.

2. DESCRIPTION
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. 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 7 standard modes, parts counting
and tare items without setting the advanced menus. Refer to the individual menus in this manual for
detailed descriptions and procedures for programming (it is usually not necessary for most
applications).
4.
UNPACKING
All iBalances are supplied with a weighing platform, AC power adapter, instruction manual, and

6.1 Turning the Balance On and Off
Will no load on the platform, press ON/TARE. All segments of the display will turn on, then the
software version will be displayed (SR 14).
NOTE: Try to allow 30 seconds for the iBalance to temperature stabilize before using. If the balance is
moved to a different temperature environment, allow additional time to stabilize.
To turn the balance off, press OFF/MODE
and hold until OFF is displayed, then release it.
6.2 Checking Calibration
Before using the balance, its calibration should be checked. The balance has been calibrated before
shipment, however, calibration is influenced by factors such as:
Variations in the earth gravitational field at different latitudes of the world.
Rough handling.
Changes in angle (even the slightest slant) or other environmental changes
Height above sea level.
To check the iBalance’s calibration, place a known mass on the center of the platform and read
the displayed weight.
If the displayed weight differs from the known mass by more than acceptable limits, refer to the
Calibration Guide and the Specifications in this manual.
6.3 Weighing
Press ON/TARE to set the display to zero.
Place the object to be weighed on the platform.
Wait until the unit indicator appears before reading the displayed weight. When the unit indicator
appears, the reading is stable.
6.4 Taring
When weighing samples that must be held in a container, taring
enables the balance to subtract the weight of the container and display only the net weight of the
sample.
Press ON/Tare with no load on the platform to set the display to zero.
Place the empty container on the platform.. It’s weight will be displayed.
Press ON/Tare . 0.0 (0.000) will be displayed and the container’s weight will be stored in the
balance’s memory.
Add the sample to the container and read its net weight on the display.
When the container and its contents are removed, the container weight will be displayed as a
negative number.
The tared weight will remain in memory until ON/Tare is pressed again or the iBalance is turned
off.
6.5 Parts Counting (optional)
Parts Counting must be enabled in the Setup menu before using
This procedure. The iBalance will count parts based on the weight of a reference sample:
5,10,20,30,40 or 50 parts. For optimum results, the parts should be uniform in weight.
Repeatedly press OFF/Mode until pc CON is displayed.
Place a container on the platform, then press On/Tare . the display will show pcADD 5 which is the
preset reference quantity. “5” shows the quantity of the reference sample.
