About the ITA Series (G) Jewellery Scale
We would like to thank you for choosing ISHTAA as your preferred choice for your
weighing requirements.
The ITA series (G) weighing balance is an accurate, fast and versatile series of balance
loaded with time saving features and ease of customer use. It is perhaps the most
economical commercial grade scale available in the market.
The scale has two 0.56” LED displays to show weight, one for the user and the other
for the customer on the back side.
There are 2 different models in this series, with capacities of 300g & 600g both with
least count of 10mg.
They all have stainless steel weighing platter on top. The loadcell is mounted on an
aluminum diecasted mounting providing precise overload protection of up to 150%
FS load capacity.
The soft touch keypad buttons are ideally sized, color coded, and bear symbolic tags
for easy recalling scale functions. The displays are large easy to read LED type
displays for easy view in different lighting conditions.
The scale is loaded with features like, automatic zero tracking, overload alarm, low
battery protection, counting, dummy zero display.
The scales feature auto zero tracking to automatically compensate for small
fluctuations in zero such as a build up of material on the platform.

2 INSTALLATION
2.1 Unpacking
Unpack and verify that the following components have been
included:
a) ITA Series (G) Precision Balance
b) Instruction Manual
c) AC Adapter
Save the packaging material. This packaging ensures the best possible
protection for the storage or transport of the product.
2.2 Placing your scale
Before you install the scale, identify the best location for the equipment.
The proper environment enhances its operation and longevity. Keep in
mind the following factors, which might have a negative influence on
the scale's operation :
a) Vibration : Vibration diminishes the scale's ability to measure
accurately. Electrical machinery such as conveyors and drill presses can
cause inaccurate and non-repeatable readings. The scale may also read
inaccurately if it is not leveled properly. The scale incorporates a Special
weighing mode where the scale can reject readings with vibration up to
some extent.
b) Drafts / Air currents : Moving air can cause the scale to read wind
movement as an additional force and cause inconsistency in the
weighing results.
c) External Rubbing / Friction: A scale cannot measure accurately if an
object is rubbing or pressing against the scale platform.
d) Moving the Scale: If you move the location of the scale it may require
recalibration. Please check the calibration when the scale is moved to a
new location.
2.3 Leveling the scale
Level the scale by turning the adjustable feet. It is leveled correctly
when the bubble indicator is in the center of the circle.
2.4 Power Source
The unit works through 9V AC Adaptor. The scale is fitted with a built
in 6V 4Ah battery which provides backup of more than 45 ~ 50 hours
depending on glow setting and sleep mode setting.
2.5 Calibration Check
Put a known weight on the machine and make sure that the scale
reads the correct weight on the display. In case of a variation in the
display reading, it is recommended to calibrate the scale again with
the procedure explained in section 6 later in the manual.

SCALE SETTINGS
5.1
CAP – This setting enables or
disables the capacity display during
startup of the scale. The valid values
are YES / NO.
5.2
BUZ: This setting enables or disables
the buzzer sound on stability of
weight. When you keep or remove
weight on the machine, once the
weight on the machine stabilizes,
the beep sound is generated. Valid settings are YES / NO.
5.3
P-OFF: This setting can enable or
disable the sleep mode. When the POFF setting is set to YES, if the scale
is idle for two minutes, that is there
is no weighing being done,
the display will simply show the
decimal point of the right most digit on the display. If machine is in idle
condition, the scale will automatically go to SLEEP mode to increase
the battery backup time. If you keep the weight, the scale will
automatically come out of the SLEEP mode and shows the weight. The
Normal backup time when the sleep mode is switched off is 30 Hours,
and with the SLEEP mode switched on, the battery back-up time
increases to more than 60 Hrs.
If the USER wants to switch off the SLEEP MODE simply set the P-OFF
setting to NO.
5.4
DSP-0 : This setting sets the no of
zeros to be shown on the display.
When the DSP-0 setting is set to
YES, if there is no weight on the pan, that is there is no weighing been
done, the display will simply show a single zero of the right most digit
of the display and if the DSP-0 setting is set to NO, the display will
show all the 4 zeros on the display. It is important to know that DSP-0
mode if set to YES increases the battery back up time.
You will now see “AUTO-0” on the scale.

6. CALIBRATION
All ISHTAA weighing scales come pre-calibrated from the factory.
However the scale may require re-calibration. Temperature changes,
geographic gravity variations, altitude changes and abuse are few
reasons why a scale may need recalibration. The scales can be calibrated
using a known external weight.
