4WORKING MODES –GENERAL INFORMATION
Weighing
Means of operation: weight of a load is determined through an indirect measurement.
A balance measures gravitational force which attracts the load. An obtained result is
processed to a digital format and displayed in a form of measurement result.
Percent Weighing
Means of operation: control of percent ratio of a sample in relation to a standard
(reference). Obtained data provides percent ratio on how test sample differs from the
accepted standard (reference).
Display shows Percentage weight in %
Differential Weighing
Means of operation: is one of Weighing application functions. It allows analysis of
sample weight variation occurring in the course of a technological process.
Display shows Differential weight in grams .
Limit Check
Means of operation: control of sample mass with applied thresholds. A user should
specify the value of min threshold <LO> and max threshold <HI>.
Display shows graph in 3 colors yellow for LOW, Green for accept, Red for High
Statistics
Means of operation: carried out measurements are used to calculate statistical data,
such as Min, Max, deviation, etc.
Calibration
TO perform Calibration - Internal and External calibration .
Animal Weighing
Means of operation: Mass measurement takes place with application of filters
dampening animal moves on a weighing pan, thus enabling obtaining a correct
measurement Threshold weight result.

4.2 CALIBRATION
Calibration is one of the primary processes used to maintain instrument accuracy. Calibration is the process of
configuring an instrument to provide a result for a sample within an acceptable range. Eliminating or minimizing
factors that cause inaccurate measurements is a fundamental aspect of instrumentation design.
To obtain weighing results, the balance must be matched to the acceleration due to gravity at its location.
Calibration is necessary
–Before the balance is used for the first time.
–At regular intervals during weighing operation.
–After a change in location.
4.2.1 Procedure for Internal Auto calibration:
To obtain accurate results, the balance must be connected to the power supply and allowed to warm up to the
operating temperature as described Ensure that the weighing pan is unloaded and close the doors of the draft
shield (if used). Balance should be Zero before calibration.

4.6 Animal weighing
Any type of movement can prevent a scale from registering a stable weight. That’s why weighing scale
manufacturers have developed specialist weighing equipment that is well-suited for weighing all types of
animals /livestock cattle and liquid etc. For the most accurate results, it’s important to use a weighing scale
with an animal/dynamic weighing function. This means the scale has the ability to provide an average
Threshold weight based on the force exerted by the animal or liquid over an extended period of time. Once
the scale completes the internal calculation, it displays an Average Threshold weight.
PROCEDURE
Press the <Animal > key on main menu on the screen,
Put the animal on weighing pan, then Press Start key animal weighing will start as shown in below
figures
Default time for animal weighing is set to 10 seconds.
.
Once it is completed the above reading will show you the normal weighing reading and the bellow
reading will freeze animal average Threshold weight reading.
