Operating Design

The balances in the GPC65-CW Series consist of a weighing cell and a display and control unit. In addition to the choice of power supply (via AC adapter or external rechargeable battery pack), your balance also has an interface port for connecting a printer, computer or universal remote control switch.

The display and control unit and the weighing cell can be set up separately. Operation of GPC65-CW balances follows a uniform “philosophy” which is described in this manual.

Keys

The functions used most often are assigned to their own specific keys. There are additional keys for assignment of other (multiple) functions, in some cases dependent on the current operating status (so-called “soft keys”). Each key is described in detail in the chapter entitled “Overview” on the CD-ROM.

Normal Operation

In the operating mode, these four keys function as c, q, w and v keys.

Setup Mode

In the setup mode, these keys take on the function of arrow keys (x, y, Y and X).

Soft Key Mode

The ‘soft key’ functions depend on the current operating status; the current function is indicated in the text line of the display. In this example, the soft keys are used to access Info, Menu and Input functions.

General Instructions for “Analytical Weighing” with Weigh Cells

Handling of Samples and Containers

Samples should be acclimatized to the temperature of the weigh cell to avoid negative effects on results, such as measurement errors and fluctuations caused by air buoyancy resulting from convection currents across the surface of the sample.

These negative effects increase as the volume and/or surface area of the sample increases. For this reason, the size of the container should be appropriate for the sample.

Samples and containers should not be touched by the operator’s hands, as the hygroscopic effect of fingerprints and the effect of the hand’s temperature can influence the measurement results. Samples must be applied very carefully, whether manually (using a forceps) or automatically (by a robot or filling system).

When designing a draft shield device, steps must be taken to keep the increase in temperature within the weighing chamber to a minimum (e.g., using a bypass).

Weighing Electrostatically Charged Samples or Containers

If a sample or container is electrostatically charged, significant errors may result during weighing. Materials with low conductivity, such as glass, plastic or filters, are particularly susceptible to static electricity (resulting, e.g., from friction) because the weighing pan can discharge the static electricity only very slowly.

The result is a force action between the charge on the sample and the permanently installed parts of the weigh cell. This causes the readout to fluctuate constantly.

Ionization can be applied to make the air around the sample conductive. This allows the charge to be compensated through the air, or discharged through the ground (grounded).

Aside from purely mechanical solutions (e.g., using a special weighing pan to shield the system), bombarding the sample with ions of opposing polarity to neutralize the surface charge is one of the most effective methods for eliminating static electricity. Sartorius can provide ionization devices for installation in weighing systems.

The area around the weigh cell can also contain charges that negatively affect the accuracy of weighing results. Appropriate steps taken in the design of a draft shield device can counteract such effects.

Weighing Magnetic or Magnetizable Samples

The use of magnetizable materials in the manufacture of weigh cells is unavoidable, primarily because the operating principle of high-resolution weigh cells is based on compensation of the load through magnetic forces.

When weighing magnetic or magnetizable samples or containers, interaction between the sample or container and certain parts inside the weigh cell may distort weighing results.

To keep such distortion to a minimum, we recommend increasing the distance between the sample/container and the weighing system using a non-magnetic material. The force is reduced quadratically with the increase in distance.

Magnetizable or magnetized samples and the weigh cell itself interact with magnetic fields and magnetizable or magnetized parts in the area surrounding the weighing system. The system can be shielded from external magnetic fields to some extent using (soft magnetic) plates.

Calibration and Adjustment

Purpose

Calibration is the determination of the difference between the weight readout and the true weight (mass) of a sample. Calibration does not entail making any changes within the balance.

Adjustment is the correction of this difference between the measured value displayed and the true weight (mass) of the sample, or the reduction the difference to an allowable level within the maximum permissible error limits.

Available Features

Your balance can be calibrated externally (menu item 1 9 1 or1 9 3) or internally (1 9 4).

External calibration can be performed

– with the pre-set weight value (1 9 1), or

– with a user-defined weight value (1 9 3)

Adjustment can be performed

– automatically following calibration

(1 10 1); or

– if desired, the adjustment operation can

be started manually after calibration (1 10 2)

You can also configure whether the calibration mode

– will be activated according to the

specific setting (by setting 1 9 1, 1 9 3 or 1 9 4), or

– can be selected by the user after

pressing the q key (1 9 12).

You can have the balance automatically display an adjustment prompt after a certain time interval has elapsed since the last calibration/adjustment or when the ambient temperature changes by a defined amount.

You can also configure the balance to perform calibration and adjustment automatically (isoCAL) when the preset time and/or temperature limit is reached (1 15 3 and 1 15 5).

You can have the calibration/adjustment results documented in a ISO/GLPcompliant printout.

This is displayed after adjustment:

5. Unload the balance Remove weight(s)

Selecting the Calibration/Adjustment Parameter

The setting 1 9 12 must be selected in the Setup menu.

You can configure the balance so that after selecting a calibration procedure by pressing the q key, you can choose among the following calibration/adjustment modes:

– External calibration/adjustment with

the pre-set weight value (Def. Ext. Adj.)

– External calibration with a user-defined

weight value (user. ext.adj.)

– Internal calibration (int. adjust)

– Reproducibility test (reprotest)

When making your selection, the available modes are displayed in cycles; i.e., after reprotest, def. ext.adj. is displayed again

External Calibration/Adjustment with a User-Defined Weight

First set either 1 9 3 or selection mode (1 9 12) in the menu.

You can define a weight for calibration/ adjustment. External calibration/adjustment must be performed with weights that are traceable to a national standard and that have error

limits which are at least 1/3 of the required tolerance of the display accuracy.

The balance has a factory-set weight value (see “Specifications”).

To reset a user-defined calibration/adjustment weight to the original factory setting, enter the factory-set weight value manually (see “Specifications”) or set menu code 1 9 1 in the Setup menu.

Internal Calibration/Adjustment

The menu code setting 1 9 4 must be selected in the Setup menu.

Inside the balance housing is a built-in, motorized calibration weight.

The internal calibration/adjustment sequence is as follows:

G Select the calibration function:

Press q

> The internal calibration weight is

applied automatically

> The balance is calibrated

> If the setting for “Calibration automati-

cally followed by adjustment” (1 10 1) is selected in the Setup menu, the balance is now automatically adjusted

> The internal calibration weight is

removed

Calibration and Adjustment Sequence

In the Setup menu, you can configure the balance so that:

– calibration is always followed automati-

cally by adjustment (cal. -> auto adjust, 1 10 1), or

– you have the choice of ending the

sequence or starting adjustment after calibration (cal. -> man. adjust, 1 10 2).

If no deviation is determined during calibration, or the deviation is within the tolerance limits dictated by the degree of accuracy you require, it is not necessary to adjust the balance. In this case, you can end the calibration/adjustment sequence after calibration. There are 2 soft keys active at this point:

– ext. adjust or int. adjust

to start adjustment

– end to end the sequence

isoCAL: Automatic Calibration and Adjustment

Either 1 15 3 or 1 15 5 must be selected in the Setup menu.

The “isoCAL” display automatically begins flashing if the ambient temperature has changed 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 self-calibrate and adjust.

This adjustment prompt is activated when:

– The change in temperature or the

elapsed time interval is greater than that shown in the table below

– The balance status does not correspond

to Setup configurations

– No number or letter input is active

– The load on the pan has not been

changed within the last 2 minutes

– The balance has not been operated

within the last 2 minutes

– The weight on the pan must be no

more than 2% at the most of the maximum capacity of the balance

When these requirements are met, the following symbols are displayed:

– C in the measured value line

–

isoCAL

in the symbol display

– G in the weight unit display

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

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

– the application program must be

restarted (On + reset app. 1 15 3), or

– the application program resumes where

it left off (isoCAL on, 1 15 5)

In the Setup menu, you can also configure the balance so that it displays an adjustment prompt, but does not perform the calibration/functions automatically (Only adj. prompt, 1 15 2)

Determination of the Repeatability (reproTEST)

Definition

Repeatability (reproducibility) 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.

Purpose

The “reproTEST” function automatically calculates the repeatability 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.

With the Counting program you can determine the number of parts that each have approximately equal weight.

Available Features

– Reference sample quantity “nRef”

loaded from long-term memory when you turn on the balance

– Optional balance configuration in the

Setup menu for automatically initializing this application and loading the most recent reference sample quantity “nRef” and average piece weight “wRef” when you turn on the balance (automatic initialization; menu code 3 10 1)

– Minimum load checked when the

balance is initialized (factory setting: 10 display increments; can only be changed by the Sartorius FastFactory)

– Reference sample quantity “nRef”

entered using the keys

– Average piece weight “wRef” entered

using the keys

– Storage parameter (level of accuracy

with which the average piece weight “wRef” is stored) for piece count calculation can be configured

– Optional configuration for having the

piece count and average piece weight output automatically via the data interface port after initialization or reference sample updating while running the Counting program (print application parameters)

– Long-term storage of the last reference

sample quantity “nRef” entered

– Long-term storage of the last average

piece weight “wRef” entered with the corresponding reference sample quantity “nRef,” by configuring automatic initialization

– Toggling between two weight units by

pressing w

– Counting program initialized again

after using the balance for weighing (after initialization)

Factory Settings

Auto-start application (automatic initialization with reference sample quantity and average piece weight loaded from long-term memory): off (3 10 2)

Counting/percent parameter (accuracy when storing average piece weights): display accuracy (3 5 2)

Printout application parameters (automatic output of application parameters): off (7 1 1)

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:

– 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;

– With automatic initialization switched

on, 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;

– Enter the average piece weight using

the numeric keys and store it.

Reference Sample Updating When the updat soft key is displayed during counting, this means you can have the average piece weight updated (while the piece count is displayed in the measured value line).

The updat soft key is displayed when:

– the balance has reached stability

– the current piece count is less than

double the original piece count

– the current piece count is less than 100

– the internally calculated piece count

(e.g., 17.24 pcs) differs from the nearest whole number (here: 17 pcs) by less than 0.3

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

Animal Weighing V

Purpose

Use this program to determine the weights of unstable samples (e.g., live animals) or to determine weights under unstable ambient conditions. In this program, the balance calculates the weight as the average of a defined number of individual weighing operations. These weighing operations are also known as “subweighing operations.”

Available Features

– Animal weighing started manually or

automatically

– Optional balance configuration in

the Setup menu for automatically initializing this application when you turn on the balance

– Minimum load threshold for starting

animal weighing: – 100 display increments for automatic

start

– 50 display increments for manual start

– Start range: Automatic start of animal

weighing operation when three successive subweights lie within a userdefined tolerance range (calm = 2%, normal = 5%, active = 10%)

– Number of weighing operations for

calculation of an average mdef can be set before the beginning of each animal weighing operation

– Arithmetic average displayed as a result

in the pre-set weight unit (identified by the G symbol)

– Optional multiplication of the arithmetic

average by a user-defined factor mul. A circle “o” is displayed as weight unit and mul=xxxx is shown in the text line

Checkweighing O

Over/Under Checkweighing O Purpose

This program is used to check whether a sample corresponds to a pre-set target value or is within a specific tolerance range. In addition to the display in the measured value line, the results are shown on the bar graph and can also be routed through the interface port via control lines for further electronic processing.

Available Features

– Lower tolerance limit (minimum), target

value and upper limit (maximum) stored in long-term memory

– Optional balance configuration in the

Setup menu for automatically initializing this application and loading the values stored in long term memory for the target value and the upper and lower tolerance limits when you turn on the balance

– Enter target value and limits by placing

a load on the balance or using the numeric keys

– Control in entering target and tolerance

values, so that the upper limit > the target > the lower limit > 1 display increment

– Accuracy of a weight readout or key-

board input as target/tolerance value stored corresponds to the display accuracy

– Optional balance configuration in

the Setup menu for automatic output to the interface port (print application parameters) of target value and tolerance limits when initialization is completed

– Control range for the balance’s data

output port lines is 30% to 170% of the target value

– Control range can be set anywhere

from 10% to infinity. Control lines set when stability is reached within the control range; deleted only when you exit this application

– Optional configuration in the Setup

menu for activation of control lines independent of weight value (weight within control range, stability reached)

– Toggling the display between weight

readout and control (checkweighing) display by pressing v. If the weight value exceeds tolerances, the measured value line shows the weight while the control display shows “LL” for “too low” or “HH” for “too high.”

– Toggle the text line display between

weight value and control display, nominal value “setp” and tolerance values “min” and “max” by pressing the w key.

– Weight displayed on bar graph in rela-

tion to upper and lower limits and target value.

– Optional automatic printout of weight

when it is within the control range at stability (auto print +/-).

After an automatic printout, the balance is blocked. Before you can generate the next printout, you must unblock the balance by unloading it (weight must be under 30% of the target) or by placing a load on the balance (bringing the weight up to at least 170% of the target).

– Press c to delete the initialization

parameters and end the over/under checkweighing program

Factory Settings

Auto-start application (automatic initialization with target value and tolerance limits loaded from long-term memory): off (3 10 2)

Automatic output of target value and tolerance limits via the interface port (print application parameters): off (7 1 1)

Auto print +/– (automatic printout of a weight when it is within the control range at stability): off (4 2 2)

Control lines +/– on (activating data output port lines): Within control range (4 3 1)

Preparation

The checkweighing program requires a target value for comparison to the current value. This target has a tolerance range, which is defined by absolute weight values: upper and lower limits. These limits can be entered either by storing weights on the balance or via key input.

There are four control lines, called data output port lines, which are activated as follows: (see also the diagram at the right):

– lighter

– equal

– heavier

– set

The control range spans 30% to 170% of the target value. You can configure this parameter in the Setup menu (4 3 +/- ctrl ports on) to select whether the control lines are:

– always on

– activated within the control range

– activated at stability

– activated at stability within the control

range

This makes it possible, for example, to connect a simple indicator for the weighing results (e.g., three different colors, one each for the weighing results: too light, O.K., too heavy).

Response of Control Lines During Checkweighing

Configurations: – always on – activated at stability

Configurations: – activated within control range – activated at stability within control range

Output port specifications – When not in use, the voltage level is high: >2.4 V/+2 mA – When in active use, the voltage level is low: <0.4 V/–2 mA.

Recalculation

Purpose

With this application program you can compensate for over-poured components in formulation.

If a component is over-poured when weighing in the individual formulation components, the mixture already poured cannot be used in its current composition. To avoid having to discard the materials weighed, you can adjust the proportions of the formulation to compensate for the over-pour.

When you use this application, the recalculation procedure is mainly performed by the balance.

Available Features

– Individual components (up to 99)

weighed in with a readout showing from “0” to the desired component weight

– Transaction counter shows the next

component expected

– Weighed components are stored, fol-

lowed by automatic printout and taring

– Additive weighing of components with

printout

– Toggle the display between component

weight and total formulation weight (additive mode) after first component is stored

– Stored component weight displayed

as true net weight for 2 seconds

– Enter a divisor before or during

component weighing. For example, if the formulation has a total weight of 100 g, enter the divisor 10 to weigh in a total formulation of 1,000 g.

– If a component is over-poured, you

can use the recalculation function to change the amount of this component indicated in the formulation by using plus or minus keys or numeric input. A factor is then calculated by which all components amounts are then adjusted.

– Recalculation factor displayed in the

text line, with a warning symbol if the factor is not equal to 1.

– All components displayed with number

and the amount (by weight) to be added in follow-on filling. Components displayed in sequence by the balance.

– Display of actual net weight during

follow-on filling

– After the amounts of the components

already weighed have been corrected, weighing continues according to the adjusted formulation amount. The readout is recalculated (updated) according to the divisor.

– You can repeat the over-pour correction

procedure as often as necessary, in case other components are over-poured.

– After follow-on (corrective) filling,

the total amount differs from that given for the formulation, but the proportion of components in relation to each other is the same.

– You can have the weight printed after

each measurement

– Choose whether the current component

weight or the tare value is printed after each measurement

– Individual component weights are

printed as “Compxx.”

– Press c to exit the application

program. The component memory is cleared and the sum of components printed as “S-Comp.”

– Minimum balance capacity; the weight must not go below this limit when

the balance is used in legal metrology (e.g., 10 g)

– Verification scale interval of the balance; irrelevant if the balance is not used in legal

metrology (e.g., 0.1 g)

– Readability: Indicates the actual scale interval (display increment of the balance)

(e.g., 0.01 g)

Bar Graph

In the bar graph, weighing results are displayed either – as a percentage of the maximum balance capacity, or – in relation to a target value, with tolerance limits indicated.

Measured Value Line

This line displays:

– The current weight readout

(digits bordered with a broken line are invalid in use for legal metrology)

Interface Port

Purpose

Your pipette calibration balance comes equipped with an interface port for connection to a computer or other peripheral device.

You can use an on-line computer to change, start and/or monitor the functions of the balance and the application programs. The interface port also has four data output port lines for the over/under checkweighing program.

!Warning When Using Pre-wired

RS-232 Connecting Cables!

RS-232 cables purchased from other manufacturers often have incorrect pin assignments for use with Sartorius balances. Be sure to check the pin assignment against the chart on the right before connecting the cable, and disconnect any lines marked “Internally Connected” (e.g., pin 6). Failure to do so may damage or even completely ruin your balance and/or peripheral device.

Data Input Format You can connect a computer to your balance to send commands via the balance interface port to control balance functions and applications.

The commands sent are control commands and may have different formats; e.g., control commands can have up to 26 characters. Each character must be transmitted according to the settings configured in the Setup menu for data transmission.

Format for Control Commands Format 1: Esc ! CR LF Format 2: Esc ! # _ CR LF Format 3: Esc ! # & (max. 20 &) & _ CR LF Format 4: Esc ! _ CR LF

Esc: Escape _: Underline (ASCII: 95) !: Command character CR: Carriage return #: Number LF: Line feed &: Number or letter max: Depends on command

character; i.e., parameter: once the max. length is reached, input received

via the interface port is cut off, rather than rejected as for a key input

Synchronization During data communication between the balance and an on-line device (computer), messages consisting of ASCII characters are transmitted via the interface. For error-free data communication, the parameters for baud rate, parity, handshake mode and character format must be the same for both units.

You can set these parameters in the Setup menu so that they match those of the on-line device. You can also define parameters in the balance to make data output dependent on various conditions. The conditions that can be configured are described under each of the application program descriptions.

If you do not plug a peripheral device into the balance interface port, this will not generate an error message.

Handshake The balance interface (Sartorius Balance Interface = SBI) has transmit and receive buffers. You can define the handshake parameter

in the Setup menu: – Hardware handshake (CTS) – Software handshake (XON, XOFF)

Hardware Handshake

With a 4-wire interface, 1 more charac-

ter can be transmitted after CTS (Clear

to Send).

Software Handshake

The software handshake is controlled

via XON and XOFF. When a device is

switched on, XON must be transmitted

to enable any connected device to

communicate.

When the software handshake is config-

ured in the Setup menu, the hardware

handshake becomes active after the

software handshake.

The data transmission sequence is as

follows:

Balance ––– byte –––> Computer

(trans- ––– byte –––> (receiving

mitting ––– byte –––> device)

device) ––– byte –––>

<––– XOFF –––

––– byte –––> ––– byte –––>

…

(Pause)

… <––– XON ––– ––– byte –––> ––– byte –––> ––– byte –––> ––– byte –––>

Transmitting Device: Once XOFF has been received, it prevents further transmission of characters. When XON in received, it re-enables the transmitting device to send data.

Receiving Device: XOFF is transmitted after the 26th character has been stored. To prevent too many control commands from being received at one time, XON is not transmitted until the buffer has transmitted all but 14 characters.

If the device addressed does not understand the control command, the SBI receiving device activates DTR (Data Terminal Ready) after 6 more characters have been received. The busy signal is deactivated by XON (14 characters).

Activating Data Output You can define the data output parameter so that output is activated either when a print command is received or automatically and synchronous with the balance display or at defined intervals (see application program descriptions and auto print settings).

Data Output by Print Command The print command can be transmitted by pressing p or by a software command (Esc P).

Automatic Data Output In the “auto print” operating mode, data are output to the interface port without a print command. You can choose to have data output automatically at defined print intervals with or without the stability parameter. Whichever parameter you select, the data will be output as the readouts appear on the balance display. The display update frequency depends on both the model of the balance and the current operating state.

If you select the auto print setting, data will be transmitted immediately the moment you turn on the balance. In the Setup menu, you can configure whether this automatic output can be stopped and started by pressing p.

Care and Maintenance Instructions

for Recycling

Service

Regular servicing by a Sartorius technician will extend the service life of your balance and ensure its continued weighing accuracy. Sartorius can offer you service contracts, with your choice of regular maintenance intervals ranging from 1 month to 2 years.

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

!Make sure that no dust or liquid enters

the balance housing

!Do not use any aggressive cleaning

agents (solvents or similar agents)

G Unplug the AC adapter from the wall

outlet (mains supply)

G If you have an interface cable connected

to the balance port, unplug it from the port

G Carefully remove any sample

residue/spilled powder by using a brush or a hand-held vacuum cleaner

G Clean the balance using a piece of cloth

which has been wet with a mild detergent (soap)

G After cleaning, wipe down the balance

with a soft, dry cloth

Safety Inspection

If there is any indication that safe operation of the balance with the AC adapter is no longer warranted:

G Turn off the power and disconnect the

equipment from AC 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 with the

AC adapter is no longer ensured when: – there is visible damage to the AC adapter – the AC adapter no longer functions

properly – The AC adapter has been stored for a

relatively long period under unfavorable

conditions

In this case, notify your nearest Sartorius

Service Center or the International Tech-

nical Support Unit based in Goettingen,

Germany. Maintenance and repair work

may only be performed by service tech-

nicians who are authorized by Sartorius

and who – have access to the required maintenance

manuals – have attended the relevant service
