7.3 INTERNAL SERVICE CALIBRATION
Internal calibration also referred as service calibration requires opening
the machine and changing the jumpers. It is advisable to do this step only
if you have required assistance or the service personnel assisting you to
do this.
Open the 4 screws from the bottom of the
machine and 1 from the ABS pan top
change the calibration jumper marked
CAL. Now place back the cover, ABS pan
and the SS pan and switch on the machine.
Make sure there is nothing kept on the
weighing pan. At this moment do not put
back the screws, simply place the cover on
the machine.
To Start Calibration switch ON the scale
and the count down will begin. Wait for a
few seconds until the display shows “CAL”.
Make sure there is no weight on the pan.
Press Zero / Enter key and the display
shows “CAL3PT” this is 3 point calibration,
you can change this setting to 1 point
calibration by pressing the Mode button
and the display will show “CAL1PT”.
Assuming you selected the 3 point
calibration, Press the Zero / Enter button
once and the display shows “0.00” for 2
seconds and then the display will show
“200.00” blinking now place the 200g of
weight on the pan and the display will stop
blinking and after 4 seconds display will
show “400.00” blinking with weight still
on the pan put another 200g of weight to
make the total weight 400g, now again
the display will stop blinking and after 4
seconds display will show “600.00”
blinking, with weight still on the pan place
another 200g 50 make a total of 600g and
the display will stop blinking. Now the
display will show “J-OFF”, lift all the
weight from the pan and change the
calibration jumper, place both the pans
and tighten all the screws and press the
Zero/Enter button once. Check calibration
to ensure the scale is reading correct.

Save the packaging material. This packaging ensures the best
possible protection for the storage or transport of the product.
3.2 Placing your scale
3.3 Leveling the scale
3.4 Power Source
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.
Level the scale by turning the adjustable feet. It is leveled correctly
when the bubble indicator is in the center of the circle.
The unit works on 220V AC Level.
The scale is fitted with a built in 6V 4Ah battery which provides backup
of more than 45 – 70 hours depending on glow setting and sleep
mode setting.
7. 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.
7.1 CALIBRATION CHECK :
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 below in section 7.2.
7.2. EXTERNAL USER CALIBRATION
To start the calibration switch on
the scale and make sure there is no
weight on the pan and the display
shows “0.000”. Now put a known
weight on the pan for eg. 200g and
the display will show “200.000”
and the display will glow. If the display
does not show the correct weight,
press and hold the ZERO button for 5
seconds till the display will show
“CALIBRATING”. With the weight still
on the pan, the display w i l l n o w
show the weight that is calibrated.
Check calibration to ensure the scale is
reading correct.
Put a known weight on the machine and
