1. Product Description
1.1 Introduction
Designed with high precision load cells and solid structures, Westlab’s Precision
Balances guarantee reliability and stability. The stainless-steel pans are corrosion
resistant and easy to clean.
The integrated rechargeable battery allows the user to move from lab-to-lab or use the
unit in an area with no access to a power source. In a teaching environment, science
educators can charge the balances before a lesson to avoid the power cords being
tangled. Additionally, the low or charged battery indicator displayed on the screen
ensures that sample weighing is not interrupted.
With a backlit LCD screen, the balances feature a simple four key menu for easy navigation.
1.2 Intended Use
The Westlab Precision Balances are intended for use in laboratories.

3. Safety Precautions
• The improper use of the unit can result in accidents and electric discharges, circuit
breakers,res,andotherdamages.
• Ensure that the balance is protected from any sudden movements or knocks, as
wellasdirectsunlightorairows.
• The balance is supplied with an adapter that is required to be plugged to an earth
connection. The socket should be ready to unplug the unit in case of an emergency.
• Do not unplug the adapter by pulling the wire. Always unplug it from the base.
• Do not use the balance in a wedged location such as a shelf.
• Do not use sharp objects such as pens to press the buttons of the control panel.
Onlyuseyourngers.
• To prevent damage to the sensor, do not place an object on the pan that is heavier
than the maximum capacity of the balance.
• Do not submerge the balance or spill liquids on it.
• When the balance is in use for extended periods of time, lock the rechargeable
battery.
• If any liquid contacts the electric parts of the balance, immediately disconnect the
unit and send it to an approved service technician.
• Always use the original components and supplies. Other devices and components
may be similar, but they can damage the unit.
4. Maintenance & Cleaning
• Do not use scourers or substances that can grate for cleaning the metallic parts
such as the stainless steel, aluminium, coatings etc on the balance. Note they can
damage and result in the early aging of the unit.
• Useaufffreeclothdampenedwithsoapedwatertocleantheunit.Ensurethatthe
soaped water does not contain abrasives.
ATTENTION! If the balances are not properly cleaned and disinfected, they will not be
repaired by our service team.

3. Connect the power cord to the power outlet.
4. Press the ‘ON’ button. The display will automatically light up and display ‘0.00g.’
Warming up
Before calibrating the balance or measuring it accuracy, it is necessary to ensure that
the unit is stable.
For balance stabilisation, it is vital that the environmental temperature is stable.
Leave the balance ON and in weighing mode for at least 15 to 30 minutes before
performing the calibration of the unit.
Calibration
Perform a balance calibration for each of the below circumstances:
• After moving the unit
• If the temperature changes a lot
• If the humidity changes a lot
The necessary calibration weight depends on the maximum capacity of the balance.

2.Placethecalibrationweightonthepanandwaituntiltheashingweightvalue
display changes to a steady state. [e.g., 1000.00 g]
3. Remove the weight from the pan. The screen will display ‘0.00’ and the balance will
return to the weighing mode.
Linearity calibration
If the tolerance [error] after calibration is too high, then linearity calibration is necessary.
1.Longpressthe‘CAL’buttonuntilthenumberashes,andlongpressthe
‘CAL’ button again.
2.Thenecessaryweightvaluewillash.

2. Place the corresponding sample of pieces in the pan [e.g., add 10 pieces on the
pan when the display shows 10 and press the ‘UNIT/COU’ button to save the data].
NOTE: In counting mode, the weight of the pieces must be even, and the weight of
an individual piece should not be less than the repeatability of the balance.
3. To return to the weighing mode, press the ‘UNIT/COU’ button again.
Weighing unit selection
The balance can perform weighing in different measuring units. In weighing mode,
press the ‘UNIT’ button repeatedly to consecutively display all the available weighing
units and select the appropriate one.
The weighing unit be default is g.
