Installation Instructions

The ME/SE balances are designed to provide reliable weighing results under normal ambient conditions in the laboratory and in industry. Choose the right location to set up your balance by observing the following so that you will be able to work with added speed and accuracy:

– Set up the balance on a completely even surface on a low-vibration balance table or

wall console

– Avoid placing the balance in close proximity to a heater or otherwise exposing the

balance to heat or direct sunlight, as this can considerably increase the temperature inside the draft shield (greenhouse effect), resulting in incorrect readouts due

to convection currents, turbulence and buoyancy effects. – Protect the balance from drafts that come from open windows or doors – Avoid brief fluctuations in room temperature – Protect the balance from aggressive chemical vapors – Do not expose the balance to extreme moisture

Linearization after Transport

After transporting the balance, its linearity may be outside the allowable tolerances

(please refer to the “Specifications” in the “Overview” chapter). After transporting the

balance, be sure to perform internal linearization. Repeat this process to obtain optimal

accuracy. For directions on this procedure, please refer to the section on “Linearization.”

Conditioning the Balance

Moisture in the air can condense on the surfaces of a cold balance whenever it is brought

into a substantially warmer place. If you transfer the balance to a warmer area, make

sure to condition it for about 2 hours at room temperature, leaving it unplugged from

AC power. Afterwards, if you keep the balance connected to AC power, the continuous

positive difference in temperature between the inside of the balance and the outside

will practically rule out the effects of moisture condensation.

Setting Up the Balance ME215/235/254/414/614

§ Place the components listed below inside the weighing chamber in the order given: – 1) Shield plate – 2) Position the weighing pan and turn to the left or right until it snaps into place – 3) Shield disk (ME235S/P only)

Sartorius office or dealer

Use only – Original Sartorius AC adapters and power cords

– AC adapters with a registered approval rating from a national testing laboratory

$ To use a main feeder cable from the ceiling or to mount a CEE plug,

have a certified electrician install it

$ To use an external rechargeable battery pack, refer to the “Accessories” in the

“Overview” chapter

§ Insert the AC adapter plug with the angle facing downward into the jack on the balance

Page 18

§ Plug power cord into the AC adapter

§ To power the balance with AC current, plug the power cord into

a wall outlet (mains supply)

Charging the Rechargeable Battery for Saving Data: All data is saved in the battery-backed memory. When initially operating the balance, leave it connected to AC power for one day to charge the battery. When the balance is disconnected from AC power, the balance-generated data will remain stored for approximately three months. In the standby mode, data is retained in the memory via the power supply. Be sure to print out data before storing your balance for a relatively long period.

Safety Precautions

The AC adapter rated to Class 2 can be plugged into any wall outlet without requiring any additional safety precautions. The ground or earth terminal is connected to the scale housing, which can be additionally grounded, if required. The data interface is also electrically connected to the balance housing (ground).

Note: This equipment has been tested and found to comply with the limits for a Class A digital device, pursuant to Part 15 of the FCC rules. These limits are designed to provide reasonable protection against harmful interference when the equipment is operated in a commercial environment. This equipment generates, uses and can radiate radio frequency energy and, if not installed and used in accordance with the instruction manual, may cause harmful interference to radio communications. Operation of this equipment in a residential area is likely to cause harmful interference in which case the user will be required to correct the interference at his own expense. Changes or modifications not expressly approved by Sartorius AG could void the user‘s authority to operate the equipment.

Connecting Electronic Peripheral Devices

§ Make absolutely sure to unplug the balance from AC power before you connect or

disconnect a peripheral device (printer or PC) to or from an interface port

Warmup Time

Each time you move your balance to another location, you must condition it for at least 12 hours to the new location. To deliver exact results, the balance must warm up for at least 12 hours after initial connection to AC power. Only after this time will the balance have reached the required operating temperature.

Using Balances Verified as Legal Measuring Instruments in the EU*:

$ The balance must warm up for at least 24 hours after initial connection

to AC power

$ Warmup time each time power is turned on the ME614S-0CE, ME414S-0CE:

at least 30 minutes

$ Always wait for the power-on adjustment routine to be completed:

Antitheft Locking Device

To fasten an antitheft locking device, use the lug located on the rear panel

of the balance.

§ Secure the balance at the place of installation, e.g., with a chain

or a lock

Leveling the Balance

Purpose:

– To compensate for unevenness at the place of installation

– To achieve perfectly horizontal positioning of the balance for consistent repeatability

of the weighing results

Always level the balance again any time it has been moved.

Only the 2 front feet are used for leveling.

§ Turn the leveling feet as shown in the diagram until the air bubble is centered exactly

within the circle of the level indicator

> Several leveling steps are usually required

Setting the Language

> See the section on “Setting the Language” in the chapter “Configuring the Balance”

Setting the Date and Time

> See the example on page 25, in the chapter “Configuring the Balance”

$ The balance must be disconnected from power before preparing it for shipment.

Disconnect the AC adapter and all interface cables from the balance.

Transport Over Short Distances

§ Place one hand under the display and control unit and the other under the back of the

balance. Lift the balance carefully and carry it to the new location.

$ Avoid subjecting the balance to vibration or shocks (impact).

! Do not lift the balance by the draft shield or the front panel, as this can result

in damage.

Transport or Shipping Over Long Distances

Make sure you use all components of the original packaging in the following cases:

– for transport or shipping over long distances. – if it is not certain that the balance will remain upright during transport or shipping.

§ Remove the following parts: – Shield disk (included with ME235S/P models only) – Weighing pan and shield plate:

Reach beneath the shield plate and lift it carefully, together with the weighing pan, to avoid damaging the weighing system.

§ Open the draft shield doors and carefully position the balance in the lower packaging.

§ Press the foam padding against the housing.

Shipping the Balance

Page 21

§ Attach the retainers to secure the front draft shield panel and the display and

control unit.

§ Place the dust cover on the display and control unit.

§ Models ME235S/P only: Place the shield disk in a bag and lay it on the dust cover.

§ Position the two padding blocks that make up the inner packaging and press inward.

§ Place the following parts in the recessed spaces at the top of the inner packaging:

– Shield plate – Weighing pan – AC adapter (in cardboard packaging)

§ Wrap the cardboard sleeve around the inner packaging.

Page 22

§ Place the strap around the package and tighten it.

§ Lift the packaged balance by the strap and place it in the shipping box, with the

bottommost padding already in the box.

§ Place the uppermost padding on top of the inner package.

§ Close the shipping box and seal it appropriately for the intended transport

or shipment.

General Instructions for “Analytical Weighing”

Handling Samples and Containers

The sample should be conditioned to the temperature inside the balance. This is the only way to avoid errors caused by air buoyancy and deviations caused by convection currents at the surface of the sample.

Since these effects increase proportionally to the volume and surface of the sample, make sure that the size of the tare vessel selected is appropriate for the initial sample.

Never use your bare hands to touch samples to be weighed. In addition to the effect of the temperature, the extremely hygroscopic behavior of fingerprints left on the sample will otherwise cause considerable interference during weight measurement.

Use forceps or a similar utensil that is appropriate to place your sample carefully on the pan. Working with your balance requires a steady hand and a smooth, uninterrupted technique.

If the weighing chamber has not been opened for a relatively long period, it may have a temperature different from that of the balance’s surrounding environment. When you open the weighing chamber, a change in temperature will inevitably occur, due to the laws of physics, and may show up as a change in the weight readout.

Operating the Balance

Therefore, we recommend that before you begin the actual weighing series you open and close the weighing chamber at the same rate as you will be doing during weighing. After the weighing chamber has been closed, the weight readout will usually stabilize after about 8 seconds. The accuracy of the weight readouts will increase as you continue weighing with greater consistency.

Weighing Electrostatically Charged Samples and Containers

Major measuring errors can occur when electrostatically charged samples and containers are weighed. This problem particularly involves samples that have extremely poor conductivity (glass, plastic, filters) since they can discharge electrostatic – i.e., friction-induced – charges only over a relatively long period of time. The result is an interaction of forces among the charges adhering to the sample and the stationary components of the balance (weighing chamber base plate, draft shield construction, balance housing). This is noticeable when the weight readout drifts. At high humidity, this effect is not very pronounced or may not occur at all, due to the thin layer of water that condenses on the sample and, through conductive discharge, counteracts interfering static electricity.

In addition to taking purely mechanical counteractive measures (protecting the sample using a special antistatic weighing pan – see the “Accessories”), you can neutralize the surface charges by “bombarding” them with ions of the opposite polarity (see page 53 for instructions on activating the ionizer). This is a highly effective procedure for eliminating static electricity.

The balance’s environment, including the operator, can considerably interfere with weighing results, due to static electricity. The balances of the ME/SE series have been designed to counteract this phenomenon: the glass surfaces of the draft shield have a special metallic coating.

The rear panel of the balance has a terminal for connecting an equipotential grounding conductor. It is used for additional grounding of a peripheral device (for example, a vibrating spatula). This terminal is designed for single grounding wires up to .25” standard gauge or 6 mm

stranded wires and for .18”

standard gauge or 4mm

stranded wires.

Weighing Magnetic or Magnetizable Samples

It is technically impossible to avoid the use of magnetizable materials in the manufacture of balances. Ultimately, the operating principle of high-resolution balances is based on electromagnetic force compensation of the load placed on the weighing pan.

When magnetic or magnetizable samples or containers (e.g., a beaker with a stirrer) are weighed, interactions among the above-mentioned components of the balance may occur, distorting weight readouts.

Unlike deviations caused by electrostatic charges, magnetic interference is usually constant over time. However, it is sensitive to and dependent on the position of the sample container on the weighing pan and is also characterized by poor repeatability.

To reduce the effect described above, we recommend increasing the distance between the sample and the weighing pan by inserting a non-magnetizable material between them (the reduction in force is proportional to the quadrate of the distance). In special cases, soft-magnetic plates should be used to shield against interfering magnetic effects.

In the presence of extremely strong magnetic fields – for instance, when measuring the susceptibility of a sample in an electromagnet – you should use the below-balance weighing port, which comes standard on your balance.

Purpose

Calibration is the determination of

the difference between the weight

readout and the true weight (mass) of

a sample. Calibration does not entail mak-

ing any changes within the balance.

Adjustment is the correction of this

difference between the measured value dis-

played and the true weight (mass) of

the sample, or the reduction of the

difference to an allowable level within

maximum permissible error limits.

Linearization is the procedure used

to eliminate the deviation from weight

readout plotted on the balance’s ideal

characteristic calibration curve and the

actual weight readout. In other words, lin-

earization reduces the amount of error of a

weight displayed to its maximum

permissible error limits. The ideal

characteristic curve is a straight line

plotted between zero load and maximum

load.

Using Verified Balances as Legal

Measuring Instruments in the EU*:

Before using your balance as a legal

measuring instrument, you must perform

“internal calibration” at the place of

In this case, you can end the calibration/ adjustment sequence after calibration. There are 2 soft keys active at this point:

–

Start to start adjustment

–

End to end the sequence

External Calibration/Adjustment with a User-Defined Calibration Weight

In the Set up menu (Balance/scale functions: Calibration/adjustment: CAL key function), you need to set

Ext. cal./adj.; user-defined wt. or select

isoCAL: Automatic Calibration, Adjustment and Linearization

First set either

On and reset the application, isoCAL and linearization on

or On without resetting

the app. (factory setting) in

the “Setup: Balance/scale functions” menu.

The “isoCAL” display automatically begins flashing if the ambient temperature changes in relation to the temperature at the time of the last calibration/adjustment, or after a defined time interval has elapsed. The balance is telling you that it wants to adjust itself.

This automatic calibration and adjustment prompt is activated when:

– The change in temperature is greater

than1.5 Kelvin or the elapsed time interval is greater than 4 hours

– The balance Setup mode is not active

– No number or letter input is active

– The load has not been changed within

the last 2 minutes

– The balance has not been operated

within the last 2 minutes

– The load on the balance does not

exceed 2% of the maximum capacity.

– When you turn on the balance after

it has been disconnected from power (only on verified balance)

When these requirements are met,

C is displayed in the line for measured

values.

If the balance is not operated and the load is not changed, internal calibration and adjustment will start after 15 seconds have elapsed.

Automatic Calibration and Adjustment at Set Times *

In the Setup menu, you can now enter up to three different times of day for automatic calibration/adjustment (see menu tree on page 55). When one of these times is reached, the balance displays the flashing calibration prompt (“isoCAL”). Calibration/adjustment is

not performed if the balance is – off (standby) or – in the Setup mode at the time set for

calibration.

If the balance is being operated at

the time set for automatic calibration/

adjustment, the calibration/adjustment

sequence will not be prompted or

performed afterwards.

Automatic calibration/adjustment

is prompted at set times when: – The set time is reached

– The balance Setup mode is not active

– No alphanumeric input is active

(e.g., equation for calculation)

– The load has not been changed within

the last 2 minutes

– The balance has not been operated

within the last 2 minutes

– The load on the balance does not

exceed 2% of the maximum capacity

* = does not apply to verified balances

In the Setup menu, you can configure the balance so that after calibration and adjustment

Purpose

The “reproTEST” function automatically determines the repeatability (also called “reproducibility”) of results (based on 6 individual measurements). In this way, the balance determines one of the most important quantities in relation to the place of installation. The results are displayed with the balance’s accuracy.

Repeatability Test (reproTEST)

Definition

Repeatability is the ability of the balance to display identical readouts when it is loaded several times with the same weight under constant ambient conditions. The standard deviation for a given number of measurements is used to quantify the repeatability.

Preparation

To calculate a piece count, the average weight of one piece must be known. This average piece weight can be entered into the Counting program in one of three ways:

– Enter the average piece weight using the numeric keys and store it;

– The last reference sample quantity entered is loaded and displayed when you turn on

the balance. Place the same number of parts on the balance and initialize the Counting program;

– When the automatic initialization parameter (see previous page), is on (Setup: > Printout:

Application-defined output: Autoprint upon initialization: All values; see page 39), the balance goes into the “counting” mode when you turn it on and loads the last average piece weight and corresponding reference sample quantity that were entered or calculated.

Reference Sample Updating

You can have the average piece weight updated during counting (with the piece count displayed) if “AWP update” is set to “manual” or “automatic” in the Setup menu. Manual updating can only be performed when the

Update soft key is displayed.

Reference sample updating must be completed before using an application program from Application 3.

The

Update soft key is displayed when:

– the balance has stabilized (stability symbol displayed)

– the current piece count is not more or less than double the original piece count

– the current piece count is more than 100

– the internally calculated piece count (e.g., 17.24) differs from the nearest whole number

(in this case: 17) by less than ±0.3

Reference updating can be repeated several times with an approximately doubled piece count.

Purpose

This application allows you to obtain weight readouts in percent that are in proportion to a reference weight. Alternatively, you can have the value displayed as a difference in percent between the weight on the balance and the reference weight, or as a special ratio1 or ratio2.

Features

– Reference percentage “pRef” loaded

from long-term memory when you turn on the balance

– Automatic initialization of this

application and loading the most recent reference percentage “pRef” entered with reference weight “Wxx%” when you turn on the balance (Setup: Application parameters: Auto-start app. when power goes on: On)

– Value displayed as:

– Residual quantity (portion) – Difference (deviation) – Ratio1 – Ratio2 depending on the selected Setup menu code

– Reference percentage “pRef” entered

manually

– Store the current weight as the

reference percentage weight “Wxx%” for initializing the weighing-in-percent application program

– Reference weight “Wxx%” entered man-

ually

– Parameter for “Weight storage

accuracy” (rounding-off factor) for storing the reference weight “W100%” in percentage calculation can be configured

– Configuration of decimal places

displayed with a percentage

– If selected in the Setup menu, automatic

output of the reference weight “Wxx%” and reference percentage in the text line and via the data interface port after initialization of the weighing-in-percent program (Setup: Printout: Applicationdefined output: Auto print upon initialization: All values)

– Toggle the display between percentage

and weight readout by pressing the

Weigh. or Perc. soft key

– Toggle between the weighing-in-percent

program and other applications (e.g., checkweighing) by pressing d

Preparation

To calculate a value in percent, the reference percentage must be known. This value can be entered into the weighing-in-percent program in one of three ways:

– The last reference percentage entered is loaded and displayed when you turn on the bal-

ance. Place the corresponding weight on the weighing platform and initialize the weighing-in-percent program;

– With automatic initialization switched on (see previous page), the balance goes into the

“weighing in percent” mode when you turn on the power and loads the last reference percentage entered as well as the corresponding reference weight (Setup: Printout: Application-defined output: Auto print upon initialization: All values);

– Enter the reference weight using the numeric keys and store it (

Wxx% soft key).

Density Determination

Page 79

Equations Used to Determine Density

Buoyancy: Rho = (Wa · (Rhofl – LA)) / ((Wa – Wfl) · Corr) + LA

For the buoyancy method, a factor of 0.99983 (factory setting) is used to allow for the buoyancy caused by the bars of the sample holder of the YDK 01 (LP) Density Determination Kit. This factor is yielded by allowing for this equation:

buoyancy of bars/wires = 2 · d

/ D2(Wa – Wfl)

The equation considers the following variables: the number of bars or wires, the bar/wire diameter of the sample holder, and the inner diameter of the vessel used.

The correction factor 0.99983 is yielded by 1 – 2 · d

/ D

where: 2 = number of wires/bars

d = bar diameter (0.7 mm) for YDK01 D = inner diameter of the vessel (76 mm) for YDK01

If you are using different vessels or other density kits, press the

Param. soft key to enter any necessary changes to this calculation

factor.

To determine the density of a solid according to the buoyancy method with our YDK 01 (LP) Density Determination Kit, make sure to use the beaker with a 76 mm diameter.

Displacement: Rho = (Wa · (Rhofl – LA)) / (Wfl · Corr) + LA

For the displacement method, a factor of 1.00000 (factory setting) is used to allow for the buoyancy caused by a wire suspended in the liquid.

If you are using different vessels or other density kits, press the

Param. soft key to enter any necessary changes in this calculation

factor.

The equation considers the following variables: the number of wires or bars, the wire/bar diameter of the sample holder, and the inner diameter of the vessel used.

This factor is yielded by: Corr = 1 – χ · d

/ D

where: χ = number of wires

d = wire diameter D = inner diameter of the vessel

Rhofl = density of the liquid causing buoyancy Wa = weight of sample in air Wfl = weight of the sample in liquid/buoyancy of sample Corr = correction for buoyancy produced by the immersed

wires or bars of the sample holder: – = 0.99983 for the buoyancy method – = 1 for the displacement method

LA = correction for air buoyancy = 0.0012 g/ccm

Pycnometer: Rho = (Wa · (Rhofl – LA)) / (Wfl + Wa – Wr) + LA

where: Rhofl = density of the reference liquid

Wa = weight of the sample Wfl = weight of the reference liquid Wr = weight of sample + the reference liquid LA = correction for air buoyancy = 0.0012 g/ccm

Purpose

This application enables you to compare samples before and after a given treatment (such as drying or ashing) and determine the difference in weight.

There are different procedures available for this application:

– Collect all data (tare, initial weight, and

backweighing result) for each sample individually (menu setting “Weighing sequence: Individual weighing”)

– Save the tare weights and initial

weights for all samples first, then perform backweighing (menu setting “Combined weighing”)

– Save the tare weights for all samples

first, then determine the initial weight of each sample and, finally, perform backweighing (serial weighing)

Differential Weighing

Page 84

Differential Weighing: Defining the Weighing Sequence

You can choose from among four sequences for measuring tare weights, initial sample weights and backweighed residue (“backweight”) during differential weighing:

1. Individual Weighing Tare weight, initial weight and backweight are measured in that order.

2. Consecutive Individual Weighing Several individual weighing routines (see above) are performed in series.

3. Combined Weighing The tare and initial weight, in that order, of each sample is measured first, then the backweight of each sample is measured.

4. Serial Weighing First the tare weight for each sample is measured, then the initial weight of each sample is measured in the same order that their tare weights were measured, and then all backweights are measured.

You can define the weighing sequence in the Setup menu or by pressing the

List Function for Differential Weighing

The list function has 4 display pages: one each for lots, samples, values and results.

Display Page for Lots

The display page for lots shows all of the lots that have already been created, as well as the number of samples in each lot and the processing status of the selected sample (tare, initial and backweight). On this display page you can create, rename, delete and print lots. You can also define a factor for calculation of loss; for instance, to have weight per unit area calculated (such as grams per square meter). You can also enter a lot ID alphanumerically to access a lot directly.

Display Page for Samples

This display page shows the samples contained in a selected lot, as well as the processing status of the samples (tare, initial and backweight) and the sample IDs. You can also enter a sample ID alphanumerically to access a sample directly.

Display Page for Values

This display page shows the date and time of sampling, as well as the sample ID and the values measured, for a selected sample.

Display Page for Results

This display page shows the calculated values for a selected sample. These include backweighed residue, loss, loss calculated using a factor, and the ratio values. The

d symbol

indicates the value that is selected for display immediately following a backweighing procedure. To change this setting, use the

q and Q soft keys to move the highlight bar to

the desired value, and press

l to confirm.

Display Page for Statistics

This page shows the characteristic data for a lot (date; time; statistics on, for example, the backweighed residue; number of samples) as well as the calculated values (mean value, standard deviation).

Purpose

This application enables you to correct weighing errors that occur due to air buoyancy when you work with weights of various densities.

You can use this application in combination with a program chosen from Application 2 (checkweighing, time-controlled functions) and one from Application 3 (totalizing, statistics).

Air buoyancy correction cannot be combined with the formulation and 2nd tare memory applications.

The air density value is required for calculation of the air buoyancy correction factor. Because not every location has an air density of 1.2 kg/m

, the density of a particular location can be determined using the air density determination routine.

Features

Buoyancy correction:

– Automatic initialization of this

application and loading the density of a weighed object stored in the nonvolatile memory,

RhoW and the air

density

RhoA last saved; display of

RhoW in the line for text.

– Automatic start of air buoyancy correc-

tion and display of the

a symbol for

calculated values, if selected in the Setup menu (Setup: Auto-start application when power goes on: Yes)

– Input of the density of a sample or an

object using the numeric keys and by pressing the

RhoW soft key. This acti-

vates air buoyancy correction, if not yet activated.

– Input range for the density of a sample:

0.1 g/cm

– 22.5 g/cm3.

– Storage of density values (

RhoW and

RhoA) in the non-volatile memory.

– Deactivation of air buoyancy correction

by toggling to the “Weighing” mode (weighing without air buoyancy correction)

Air Density Determination:

– To determine the air density, use the

special weight set, YSS45, which is available as an accessory. This weight set consists of one steel and one aluminum weight and is available with the “Weight Specifications” certificate. The densities of the steel (8.0) and aluminum references (2.7) are preset values and cannot be changed.

– Determine the air density by

– entering the density using the

numeric keys

– entering the specifications for

steel/aluminum and weighing the steel and aluminum weights (accessory: YSS45)

– If you enter an air density using

the numeric keys, the reference values (density and weight) for steel and aluminum are deleted from the display page “AIR D. PARAMETRS.”

– After the air density has been

determined and saved by pressing the

Start soft key, the reference values

are printed out

– Preset value for air density: 1.2 kg/m

– Range for entering air density values:

1.0 kg/m

– 1.4 kg/m3.

– You can activate or deactivate air

density determination in the Setup menu, thus blocking access to this program routine.

– The air density is generally determined

in grams as the weight unit.

– If air density determination is deactivated,

the air density

RhoA will be displayed

for 2 seconds in the text line when you press the

RhoA soft key.

– After the air density has been

determined, you can save the value, but this is not required

– You can block storage of the specifica-

tions (references) in the Setup menu. (Setup: Application parameters: Application 1: Air buoyancy correction: Change steel/aluminum references)

– The density values on the display page

for reference values are standard, inalterable values

Equations for Air Buoyancy Correction

To determine the mass of a sample, its weight is multiplied by the following factor K:

K = (1 – Rho

/ RhoST) / (1 – RhoA/ RhoW)

where:

Rho

= air density [kg/m3]

Rho

= density of steel (8,000 kg/m3)

Rho

= density of the sample [kg/m3]

Add the mass error to the weight

Air Density Determination

Equations for Air Density Determination

The balance uses the equation below to calculate the air density for steel and aluminum based on the reference weights supplied:

· W

–mST· W

RhoA= –––––––––––––––––––––––––––––––––

· W

mST· W

–––––––––– – ––––––––––– Rho

Rho

where: Rho

= air density [kg/m3]

Rho

= density of aluminum [kg/m3] RhoST= density of steel [kg/m3]

= mass of aluminum mST= mass of steel

= weight value of aluminum WST= weight value of steel

The mass of aluminum is calculated according to the following equation:

=MAL· (1 – 1.2 / 8000) / (1 – 1.2 / RhoAL)

where: m

= mass of aluminum (specification)

= conventional mass value of aluminum

Rho

= density of aluminum [kg/m3]

The mass of steel is calculated according to the following equation:

=MST· (1 – 1.2 / 8000) / (1 – 1.2 / RhoST)

where: m

= mass of steel (specification)

= conventional mass value of steel

Rho

= density of steel [kg/m3]
