, please read this manual completely .
2. DESCRIPTION
The iBalance 201 portable advanced balance is a precision
weighing instrument, designed to provide years of service with virtually no
maintenance. The iBalance 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
iBalances are initially factory set to measure in 7 standard units of measure.
The iBalance operates through a series of menus that 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 warranty card.

environment, allow additional time to stabilize.
To turn the iBalance off, press and hold the OFF/Mode key
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:
⑴ Variations in the earth gravitational
field at different latitudes of the world.
⑵ Rough handling.
⑶ Changes in angle (even the slightest
slant) or other environmental changes.
⑷ 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
⑴ Press & release ON/Tare to turn the
scale on and set the display to zero.
⑵ Place the object to be weighed on the
platform.
⑶ Wait until the unit indicator stops
flashing before reading the displayed weight. When the unit indicator is stable,
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.
⑴ Press ON/Tare with no load on the
platform to set the display to zero.
⑵ Place the empty container on the
platform.. Its weight will be displayed.
⑶ Press ON/Tare, 0.0 (0.000) will be
displayed and the container’s weight will be stored in the balance’s memory.
⑷ Add the sample to the container and
read its net weight on the display.
⑸ 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.
⑴ Repeatedly press until
pc CON is displayed.
⑵ Place a container on the platform,
then press . the display will show pcADD
5 which is the preset reference quantity. "5" shows the quantity of the
reference sample.
⑶ To change the reference quantity,
repeatedly press until the desired quantity is displayed.
NOTE: If you need to exit or restart parts counting at any
time, press and
hold until pc
CON is displayed, then immediately release (if you hold onto the
ON/Tare key for too long the scale will go into Calibration or Setup mode).
Return to step 2 to
restart, or press ON/Tare for other weighing functions.
⑷ Add the displayed number of parts to
the container, then press
. The display will show the current number of parts (ie 5).
NOTE : If PCErr is displayed, the sample is too small to
provide accurate results within the selected parts counting error level (This
can be adjusted in the PCErr section of the Setup menu).
⑸ Add parts to the container as desired
and read the quantity on the display. The small "PC" indicator will show on the
left side of the display.
NOTE : The programmed quantity/weight (ie 5) will remain in
memory until it is changed or the iBalance is turned off..
