2.1 Location
The optimum location
The correct location makes an important contribution to the accuracy of the weighing
results of high-resolution analytical and precision balances.
Hence, ensure a stable, vibration-free position as horizontal as possible.
Avoid
• Direct sunlight
• Excessive temperature fluctuations,
• Drafts (Power ----- Air Conditioning System, Fans can also cause drafts)
The best position is an a stable bench in a corner protected against drafts as far
possible from doors, windows, radiators or the ventilation slots of air conditioners.

Leveling the Balance
BL Series balances have a level control and adjustable leveling feet to compensate for
slight irregularities in the weighing bench surface. The balance is exactly horizontal
when the air bubble is in middle.
Before plugging to mains, level the balance by turning the adjustable feet in a way
that the air bubble of the level is in its central ring. The balance should be placed at the
workplace firmly on all of its feet.

6. Functions
6.1 Piece counting
Procedure
Piece counting presupposes that you have preselected the “F count” function in the
menu
ð
Place the empty container on the pan.
ð
Press the <TARE> key briefly to tare the balance.
ð
Press the <TOGGLE> key briefly until “PCS” appears on the display.
Your balance now needs the weight of a reference number.
ð
Press and hold the <TOGGLE> key until you are prompted to load the reference
pieces.
ð
Your balance suggests the last set reference no. as the reference number.
You can accept this suggestion or select one of the other reference numbers
available (5, 10, 20,50, 100 pieces, Free, wref, Update) by briefly pressing the
<TOGGLE> key.
Note : We recommend you to choose a reference number as high as possible as the
balance determines the average weight per piece and stores it as the reference
weight. As it is seldom, that all pieces weigh exactly the same, the larger the reference
number selected, the greater the accuracy of the reference weight. This application
assumes uniform weight of each piece.
ð
When you have placed exactly the same number of pieces on the weighing pan as
selected reference pieces press TARE key.
As soon as the weighing result is stable, the calculated average piece weight is
accepted as the reference.
ð
After your balance has determined the piece weight, it displays the pieces as per
selected number and is now ready for piece counting.
You can use the <TOGGLE> key at any time to switch the display between the
piece number display, weighing unit 1 and weighing unit 2.
Note : The current set weight remains stored until it has been redetermined.
40

If the piece weight is known, it can be entered directly. To do this, press the TARE key
when the system displays wRef in the reference menu. An input field appears, in which
the piece weight can be entered.
Since the balance does not have to determine a reference by weighing, the result of
the piece counting (the number of pieces currently on the weighing pan) is displayed
right after the piece weight has been confirmed.
Procedure
ð
Place the empty container on the pan.
ð
Press the <TARE> key briefly to tare the balance.
ð
Press the <TOGGLE> key briefly until “pcs” appears on the display.

42
6.1.3 Updating Settings
The Update feature improves the precision of piece counting results.
The average piece weight (reference) is recalculated with each reference
optimization. Because the new pieces that have been placed in the weighing pan
increase the basis for the calculation, the references, and therefore the result of the
piece count, are more exact.
Select the UPDATE feature from the reference menu. The reference can be updated
by pressing the CAL key which is confirmed by the displaying 'UPDATED' on the display.
Note
• The number of pieces placed in the weighing pan is larger than the reference piece
number shown on the display.
• The number of pieces placed in the weighing pan is not greater than twice the most
recently saved reference piece number (e.g. If the display shows 100 pcs the
added pieces should not be greater than 200).
• Update feature cannot be selected if the previous selected reference was 'wRef'
43
If the balance is connected externally to PC or Printer through RS 232 C then, whenever user enter into the reference menu of Piece Counting
function & make changes in the reference setting, automatically printout is generated on the Peripheral attached.
In the printout, reference number “nRef” and reference weight “wRef” is printed. After this user can Press Print Key to Print the reading on the display.

6.2.2 Differential Weighing
The Differential Weighing application is used to analyze changes in the weight of one
or more samples. The first step is to determine the initial weight of the sample (weighing
in). Selected components are then separated from or added to the sample. This
includes procedures such as drying, centrifugation, filtering, incineration, vaporization,
coating, etc. After the sample has been processed, it is re-weighed (residual weight).
The balance then determines the difference between the two weighed values.
100L% (Loss Content)
100L
100R% (Residual Content)
100L (Loss)
The moisture content of the sample is displayed (and printed out) as a percentage of the
wet weight (= ww = initial weight = 100%). When the results are printed out, the moisture
content is designated 100L % " (Loss) (e.g. –11.35 100.00L%) and shown as a negative
value.

The density is determined applying the principle of Archimedes, which states that any body
immersed in a fluid becomes lighter by an amount equal to the weight of the fluid that it has
displaced.
Purity of gold can also be determined on the basis of density.
The weighing unit of density determination will be 'grams'.
Density determination presupposes that you have selected the 'F Den' in the user menu.
To calculate the density of sample, the balance should know the type of liquid and its
temperature, used to calculate the density of solid.

Density Calculations
With compensation for air density
Display for compensated density
ñ =
A * (ñ0 - ñl)
+ ñl
(A - B)
ñ = density of sample
A = weight of sample in air
B = weight of sample in auxiliary liquid
ñ0 = density of auxiliary liquid
ñl = air density (0.0012 g/cm3)
e.g.
ñ = (A / (A - B)) (ñ0 - ñl) + ñl
= (20.000 / (20.000-18.935)) (0.99689 – 0.0012) + 0.0012
= 18.699 g/cm3
Display for uncompensated density
Without compensation for air density
ñ =
A
ñ0
(A - B) *
ñ = ñ0 (A / (A - B))
e.g.
ñ = ñ0 (A / (A - B))
= (20.000 / (20.000-18.935)) (0.99689)
= 18.721 g/cm3

Solution
Overload
Remove excess weight from the weighing pan.
Under load
• Keep weighing Pan on Weighing Shaft.
Check whether weighing pan is positioned
properly.
Weight set is to low for storing any reference at PCS,
%, Custom Unit or Check Weighing.
Increase weight on the pan.
While calibrating the scale, the load on the pan is
more than 10% of the capacity. (During power on
of the scale.)
Switch OFF the Balance and Switch ON again
without any load on the pan.
Calibration
• User does not keep any weight on the pan within
60 second.
• Weight load on the pan is not within the tolerance
limit.
• Add the calibration weight on the pan when
demanded by the balance
• Calibrate with the exact Calibration Weight.
GLP is ON and user tries to enter in to the User Menu
before the footer is printed.
Print the footer first, by pressing <CANCEL> key, and
then access the USER MENU.

11. Care & Maintenance
Service
Regular servicing by a Supplier / Dealer technician will extend the service life of your balance and ensure its continued weighing
accuracy.
The optimum maintenance interval depends on the operating conditions at the place of installation and on the individual
tolerance requirements.
Repairs
Repair work must be performed by trained service technicians. Any attempt by untrained persons to perform repairs may lead to
hazards for the user.
Cleaning
• Unplug the DC adapter from the wall outlet
(mains supply). If you have an interface cable connected to the balance/scale port, unplug it from the port.
• Make sure that no liquid enters the balance/scale housing
• Do not use any aggressive cleaning agents (solvents or similar agents)
• Clean the balance/scale using a piece of cloth which has been wet with a mild detergent (soap)
• After cleaning, wipe down the balance/scale with a soft, dry cloth
110
Cleaning Stainless Steel Surfaces
• Clean all stainless steel parts regularly. Remove the stainless steel weighing pan and thoroughly clean it separately.
Use a damp cloth or sponge to clean any stainless steel parts on the scale. You can use any commercially available household
cleaning agent that is suitable for use on stainless steel. Clean stainless steel surfaces by wiping them down. Then clean the
weighing pan thoroughly, making sure to remove all residues. Use a damp cloth or sponge to wipe down any stainless steel parts
on the scale again. Afterwards, allow the scale to dry. If desired, you can apply oil to the cleaned surfaces as additional
protection.
• Do not use stainless steel cleaning agents that contain soda lye (caustic), acetic acid, hydrochloric acid, sulfuric acid or citric
acid. The use of scrubbing sponges made of steel wool is not permitted. Solvents are permitted for use only on stainless steel parts.
Safety Inspection
If there is any indication that safe operation of the balance/scale with the DC adapter is no longer warranted:
• Turn off the power and disconnect the equipment from DC power immediately
• Lock the equipment in a secure place to ensure that it cannot be used for the time being.
• Safe operation of the balance/scale with the DC adapter is no longer ensured when:
• There is visible damage to the DC adapter.
• The DC adapter no longer functions properly.
• The DC adapter has been stored for a relatively long period under unfavorable conditions.
