2INSTALLATION
2.1 Unpacking
Unpack and verifythat the following components have been included:
a) Hax Series Hanging Scale
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 Hanging 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 SMART
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: Ascale cannot measure accurately if an
object is rubbing or pressing against the scale hook.
2.3 Power Source
The unit works through 6VAC Adaptor. The scale is fitted with a built in 6V
4Ah battery which provides backup of more than 30 ~45 hours depending
on glow setting and sleep mode setting.

2.4 Calibration Check
Hang a known weight on the machine and make sure that the scale reads the
correct weight on the display. In case of a variationin the display reading, it is
recommended to calibrate the scale again with the procedure explained in section
7.1 later in the manual.

4USER OPERATION
4.1 SWITCHING SCALE - ON / OFF The scale is switched ON / OFF by using the
Power switch located on the back side of the scale.
Note: Make sure there is no weight hangedbefore turning on the scale.
4.2 TARE / ZERO : The machine has a common Tare/Zero button. TARE /
ZERO BUTTON: This button is used for taring a weight to display 0.00. Hang a
Bowl on the hook (say 200g), then press the TARE button. The weight is zeroed
and the machinewill display zero.
4.3 ACCUMULATION: Hang a weight on the Hook (ex 200g). The display will show
the weight. Now press M+. The display will show “n ...” total no. of items weighed
and then the total weight. Now hang another weight (ex 300g), the display will
show its weight, now press the M+ button, the display will show the no. of items
and the total weight. To recall the accumulated weight press the M+ button.
4.4 HOLD FUNCTION: This function enables you to hold a particular weight that is
being displayed on the display of the scale so that the user can see the accurate
stable weight until the hanged weight is lifted back from the hook. To hold the
weight just hang some weight to the scale and press the “ M+ ” button and you
will notice the displayed weight has been hold with the hold led blinking, now
remove the hanged weight and the scale will automatically return to the
weighing mode.
4.5 MODE This button is used to select the different values available in the scale
settings mode. This button is also used to display the internal counts. Press and
hold the button and switch on the scale until display shows the internal counts.

5.5 SLEEP MODE: The scale has a power saving mode called the SLEEP MODE.
Whenever the scale is switched on, the SLEEP MODE is by default set to ON
condition. In this mode, 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. Whenever any weight is hanged, the scale will
automatically come out of the SLEEP MODE and start displaying the weight. It is

Hax Series Hanging Scale

important to know that SLEEP mode increases the battery back-up time by double.
The Normal backup time when the sleep mode is switched off is 25 Hours, and
with the SLEEP mode switched on, the
battery back-up time increases to more
than 40 Hrs. If the USER wants to switch

now show “SLEEP0”. Press the Tare/Zero button till scale comes to the weighing
mode. Now the Sleep mode has been switched off.
5.6 DUMMY ZERO: This feature enables you to get an extra zero on the rightmost
digit of the display that is the dummy zero actually which is only displayed and
does not work. If the user want to add a dummy zero for some special usage or
function it can be done as follows: When the
scale is in then weighing mode, While

6CALIBRATION
All SMART 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.
