Operation

Notes on Analytical Weighing with Weigh Cells

Handling of Samples and Containers

Samples should be acclimatized to the temperature of the weigh cell. This is the only way to avoid measurement errors caused by air buoyancy and fluctuations 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 tare container should be appropriate for the sample.

Samples and containers should not be touched by the operator‘s hands. This is because 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 and Containers

Significant measuring errors can occur when electrostatically charged objects 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 through the weighing pan over a relatively long period of time only.

The result is a force acting 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 sample), 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, like plastic parts, can also contain charges that negatively affect the accuracy of weighing results. Appropriate steps (grounding) taken in the design of a draft shield device can counteract such effects.

The weigh cell base plate and the electronics base plate should be grounded via the screw connections.

Weighing Magnetic or

Magnetizable Samples

It is technically impossible to avoid

using magnetizable materials for the production of weigh cells. This is 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 the above-mentioned parts inside the weigh cell may have a distorting effect on the weighing results.

To keep such effects to a minimum,

we recommend increasing the distance between the sample/container and the weighing system using a nonmagnetic 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.

Effects of Drafts

Depending on the size of the load receptor and the sample, the effects of drafts may occur. To minimize this effect, install a draft shield for protection. Protect the weigh cell from drafts.

Calibration/Adjustment

Calibration/adjustment can be

performed as follows:

– Using control commands sent by the

CAS-Suite configuration software from Sartorius, installed on a computer (see page 22 for the commands)

$ Using the optional YAC01ED

control unit

Commands (Data Input Format Compatible with Current Weigh Cells)

The computer connected via the data port can send commands to the weigh cell for controlling functions. The commands sent are control commands and may have different formats. Control commands consist of up to 13 characters. Each character must be transmitted according to the settings configured in the operating menu for data transmission.

Formats for Control Commands Format 1: Esc ! CR LF Format 2: Esc ! # _ CR LF

Esc: Escape (optional) CR: Carriage return !: Command character LF: Line feed (optional) _: Underline Command character Format 1: ! Meaning

K Ambient conditions: very stable L Ambient conditions: stable M Ambient conditions: unstable N Ambient conditions: very unstable O Block keys P Key r (print, auto print; activate or block)

) Q Acoustic signal R Unblock keys S Restart | Self-test T Tare | Zero: Key “w” U Tare V Zero W Calibrate | Adjust depending on menu setting Z Perform internal calibration/adjustment

)

Command character Format 2: !# Meaning

f0_ Function key

f1_ Function key Q Calibrate | Adjust (depending on the menu setting) f2_ Function key u s1_ With »s8_« compatibility: Toggle selection in steps of 1

With »s9_« compatibility: Adjust according to menu setting

s2_ Activate parameter mode (selection) s3_ Key c s8_ Compatibility: Consistent with current weigh cells (from 2013) s9_ Compatibility: Consistent with older weigh cells (previous models) x0_ Perform internal adjustment x1_ Print model x2_ Print serial no. x3_ Print software version

) When initiating the print command, the data output rates may differ: see table on next page.

) Only on models with internal weight circuit

Page 23

Synchronization

During data communication between the weigh cell and a connected device (computer), messages consisting of ASCII characters are transmitted via the interface. For error-free data exchange, parameters for baud rate, parity, handshake mode and character format must be identical for both units.

You can set these parameters in the Setup menu so that they match those of the connected device. You can also define parameters in the balance/scale to make data output dependent on various conditions. These conditions are described under each of the application program descriptions. No errors are generated just because no peripheral device is connected to an interface port (open data port).

Handshake

The weigh cell interface (Sartorius Balance Interface = SBI) has transmit and receive buffers. You can define the different handshake parameters in the Setup menu of your

weigh cell: – Hardware handshake (CTS/DTR) – Software handshake (XON, XOFF) – No handshake

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.

Data Output by Print Command

The print command can be transmitted by pressing r or by a software command (Esc P).

Automatic Data Output

Activate the “Auto Print” operating mode to have data output to the interface port without a print command. You can have synchronized data output automatically at defined display update intervals, with or without the stability parameter. The length of a print interval depends on the operating menu settings for Ambient (ambient conditions, menu code 1. 1. 1. x) and aut.cycl. (time-dependent autom. printing, menu code 1. 6. 3. x). If you activate the auto print setting, data will be transmitted immediately the moment you turn on the balance/scale. In the operating menu, you can define whether automatic printing can be stopped and started by pressing the “Print” key or using the interface.

Hardware Handshake

When hardware handshake is

configured on a 4-wire interface,

1 more character can be transmitted

after CTS.

Data Interface: Compatibility with Older Weigh Cells (Previous Models)

Once command »ESC s9_« has been sent, data input and data output behave as in the earlier Sartorius WZ-/WZA weigh cells (previous models).

Data Output Format

In operating mode »SBI«, 16 characters are printed out. Example:

+ 253 pcs

Data Output Format with 16 Characters

Characters that are displayed blank are printed as spaces. Display values without a decimal point are output without a decimal point.

The type of character that can be output depends on the character‘s position:

Normal Operation Position 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16
