Semi Micro/Analytical Balance:

Semi Micro/Analytical balances based on electromagnetic force compensation (EMFC) as a principle for
achieving precise and stable weighing measurements.

EMFC is a technology that utilizes electromagnetic fields to counteract the gravitational force exerted on
the object being weighed.

A semi-micro balance with dual-range capability is a highly precise laboratory instrument designed for
measuring masses in the sub-milligram range.

Its "semi-micro" designation indicates its ability to handle extremely small quantities with precision,
while the "dual-range" feature allows it to switch between two measurement ranges for versatility in
weighing a wide range of sample sizes.

Its application spans various scientific fields, including chemistry, biology, pharmaceuticals, and
materials science.

Our Semi Micro/Analytical scale & balance are used for Scientific Investigation or for research Lab.

16. WHEN TO CALIBRATE:
Calibration of a balance is needed:
1. During Initial Installation:
To establish accurate baseline measurements.

2. After Relocation:
Due to changes in environmental conditions during movement.

3. Periodically:
Regularly scheduled to maintain accuracy over time.

4. After Repairs:
To ensure modifications do not affect accuracy.

5. If Inaccuracy is Detected:
Immediate recalibration is required if the balance shows signs of inaccuracies

6. Due to Changes in Environment:

Especially in response to significant temperature or humidity changes.

7. Over Time for Mechanical Deviations:

If machine is not used for a long period to detect and
correct wear or deviations in the balance's components.

17. CALIBRATION:
AUTO CALIBRATION:

In this mode, the parameter setting should be set to C1-00 (factory

setting).

Plug in and pre-warm the balance at least 30 minutes;

Turn on the balance;

The balance will be calibrated automatically after several minutes and whenever the
environment temperature changes out of a definite limit over ±2C or it works out of the time
limit over two hours.

NOTE: If " "(No calibration) is twinkling.

20
 Check if there is any object on the pan or the build-in calibration weight is loaded down onto the
weighing mechanism while calibration

Remove the objects on the pan or raise up the build-in calibration weight from the weighing
mechanism;

Press SET key then CAL key to raise the build-in calibration weight up when it is on the weighing
mechanism;

ONE TOUCH CALIBRATION

In this mode, the parameter should be set to C1-00 (factory setting).

Plug in and pre-warm the balance at least 30 minutes before Calibration;

Turn on the Balance

Keep the empty PAN

Press CAL Key after “Zero” is displayed

The Balance will be Calibrated automatically. The Display as same as that in Auto Calibration
mode.

18.MINIMUM WEIGHING CAPACITY:

Min.
Every balance minimum weight is different, depending on Readability (d) and verification scale intervals
(e) with ambient conditions.

The minimum weight must be follow for the accuracy of the instrument. If any sample fall below this
minimum weight, the relative measurement uncertainty becomes greater than the required weighing
accuracy. Consequently, the weighing result cannot be considered reliable.

If a weighing is below the determined acceptable minimum value, the balance may display a load value,
and the weighing results may be subject to an excessive relative error.

The verification of scale interval, number of verification scale interval and the minimum capacity, in
relation to the accuracy class of an instrument
Class I minimum capacity 100e
Class II minimum capacity 20e
Class III minimum capacity 50e

21
19. IDEAL CONDITIONS:
o As this is a dual range balance (0.01mg/0.1mg), Use the balance as per it's Weighing capacity &
application. 5 digits mode is used when there is specific very small quantity of sample to be
measured. 4 digits mode balance for normal & regular use.

o Anti Vibration Table must for semi micro & Analytical Balance.

o Level the balance using the leg ferrule adjusters and the in-built spirit level.

o Warm up the Balance around 1 hr. before use every day.

o After warm up, Calibrate the balance ( internal calibration).

o Balance should be kept away from dirt and dusty areas, Dust can damage internal components.

o Do not keep more weight as per maximum capacity.

o Moving the balance from one place to other place should be avoided.

o Humidity 40% to 60% with a maximum of + 10% per 4Hrs.

o Operating Temperature + 15°C to 30°C, Recommend temperature 23°C + 2°C for better
performance.

o Ambient temperature during the measurement should not be change + 0.7°C per Hr.

o Vibrations from Generator, refrigerators, ventilation systems, and other equipment that produce
vibrations can affect the precision of an semi micro & analytical balance.

o For 220V Stable Power Supply, use stabilizer.

o Air condition direction should not be in front of the balance to avoid moisture form inside the
mechanism.

o Air pressure from ceiling fans, air conditioners, and open doors can also cause sensitive
equipment to show wrong measurements.

o For Weighing, put your materials on Weighing pan very very slowly , Close Glass Windshield very
slowly.

o Keep magnetic field things far away as it will effect on the measurement of the machine.

o Place the sample in the center of the balance for the most accurate results.

22
o Electrostatic charges can cause unstable, non-repeatable weighing results. Static electricity
exerts a force on the weighing pan, which directly affects semi micro & analytical balance results.

o Plastic and glass weigh containers can hold an electric current. Static charges can result in
nonrepeatable measurements or drifting measurement readings, Use antistatic weighing
containers (metal is ideal), Avoid rubbing containers use a metal dish with an edge to help shield
the electric fields.

o To ensure semi micro & analytical balance static elimination, discharge the sample and container
with an ionizer before weighing.

o Below minimum weight, the relative measurement uncertainty is larger than the required
weighing accuracy, and the weighing result cannot be trusted.

o Test with certified E2 Class weights, if necessary. Weights also need warm up.

o Hot or warm samples should be cooled first upto room temperature. Hygroscopic samples need
to be weighed quickly with the balance doors closed to avoid absorption of moisture. Not
following these steps will affect the measurements.

o To clean semi micro & analytical balance It is recommended to use a non-abrasive cloth like lint-
free microfiber towel to wipe down the inside of the weighing chamber.

o When not in use, put dust cover on balance to maintain its reliability and accuracy.

23
