The filling speed can be set in terms of seconds from 20 to 999. The standard setting of this value is 30 seconds. For diluted aqueous solutions the filling speed can be six to 20 seconds. For non-aqueous solutions the filling speed should be set to the 30 seconds. In the case of highly viscous solutions such as concentrated sulphuric acid the filling speed should be further reduced down to 40 - 60 seconds.

Depending on the method type, the (maximum) the living volume or titration volume can be set to 999.999 or even 9999.999.

4.5.4 Sample identification

In the manual titration it is possible to input a sample identification. The possible input includes manual, automatic or no sample identification at all.

Fig. 62 For the manual sample ID, a prompt for the sample ID will always be displayed at the start of the method (Cp.

also chapter 3.6, Main menu). For an ‘automatic’ sample ID there will be selected a master ID (in the current case this is water, cp. Fig. 68), which will then automatically be numbered starting on 01.

If no valid update file is stored on the USB stick, the following message will appear:

Fig. 99

6 Connection of Analytical Balances

As it often happens that the sample is weighed in on an analytical balance, it makes sense to connect this balance to the TITRONIC® 300. To connect the balance to the TITRONIC® 300, the balance must have a RS232-C-interface and the connection cable must be configured accordingly. For the following types of balances there are already assembled connection cables:

Balance TZ-Number Sartorius (all types with 25 pin RS) TZ 3092 Mettler, AB-S, AG, PG TZ 3099 New Sartorius balances with USB-Interface (via RS-converter) TZ 3099 Precisa XT-Series TZ 3183 Kern with 9-pole RS232 TZ 3180

For all other types of balances it is possible to obtain an already assembled connection cable (on demand). For this we need detailed information about the RS-232-C-interface of the balance used.

The connection cable is to be connected to the RS-232-C-interface 2 of the TITRONIC® 300. This side of the connection cables always consists of a 4-pole mini-plug. The other side of the cable can, depending on the type of balance, be a 25-pole plug (Sartorius) or a 9-pole plug (Mettler AB-S).

In order to allow the balance data to be sent to the TITRONIC® 300, the data transmission parameters of the titrator and the balance must correspond to each other. Additionally, it is necessary to carry out some more standard settings on the side of the balances:

 The balance is to send the balance data via RS-232-C only by means of a print command.  The balance is to send the balance data only after the display standstill.  The balance should never be set to ‘automatic sending’ and/or ‘send continuously’.  ‘Handshake’ on the balance must be set to ‘off’, or even ‘Software Handshake’ or ‘Pause’.  No special characters such as S or St are allowed to be used as prefix in the balance data of the balance

data string. In such a case it might be possible that the TITRONIC® 300 cannot process the balance data correctly.

After you have connected the balance with the appropriate cable to the TITRONIC® 300 and have adjusted all settings in the balance software, and possibly in the TITRONIC® 300, you can now test the data transfer of the balance very easily. Start the one method. Confirm the sample designation. Then, the display asks you:

a) To press the print-button at the balance  Parameters to ‘weighted sample automatically’ b) To enter the weighted sample  then the parameters are still set to ‘weighted sample manually’

Put an object onto the balance and press the print button. After the standstill of the balance display there will be beep at the TITRONIC® 300 and the transmitted balance data appear:

 After approx. 5 sec. in the display and the display changes automatically into the measuring display.  The weighted sample must again be confirmed with <Enter> or <F1>.

6.1 Balance data editor

Pressing the die <F5/balance symbol > function key will invoke the so-called balance data editor. A list with the existing balance data will appear:

Fig.100 The balance data can be edited one by one. Following a change, a star will appear opposite the weighed-in

quantity:

Fig. 101 Weights may be deleted or added individually. It is also possible to delete all weights at one stroke.

Fig. 102 If no balance data is available, the “No balance data found” message will appear.:

7 Data Communication via RS-232- and USB-B interface

7.1 General Information

The burette TITRONIC® 300 has two serial RS-232-C interfaces to communicate data with other devices. By means of these two interfaces it is possible to operate several devices on one computer (PC) interface.

In addition to that, the TITRONIC® 300 also has an alternatively USB-B interface, which can only be used to connect a PC.

RS-232-C-1 establishes the connection to a connected computer or to the previous device of the “Daisy Chain”. At the RS-232-C-2 it is possible to connect additional devices (Daisy Chain Concept).

PIN assignment of the RS-232-C interfaces:

7.2 Chaining multiple devices — „Daisy Chain Concept“

In order to activate several devices in a chain individually, each device must have an own device address. For this it is at first necessary to establish a connection from the computer to the RS-232-C interface 1 of the first devise in the chain by means of a RS-232-C data cable, e.g. Type No. TZ 3097. With the additional RS-232-C data cable, Type No. TZ 3094, the RS-232-C- interface 2 of the first device is connected with the RS-232-Cinterface 1 of the second device. At interface 2 of the second device it is possible to connect an additional device.

The TITRONIC® 300 can also be connected via USB cable TZ 3480 (type A (M) – type B (M), 1.8m). It is also possible to connect the TITRONIC® 300 via a mini USB to a USB interface of a PC. To accomplish this connection, a driver has to be installed on the PC. Then the USB-B interface takes over the function of the RS232-1 interface. Please contact SI Analytics for acquiring the software.

The address always consists of two characters: e.g. address 1 of the two ASCII- characters <0> and <1>. The addresses can be set from 00 to 15, i.e. 16 possibilities. It must be ensured that the devices in a chain have different addresses. If a device is addressed with its address, this device will process this command without sending it to another device. The reply to the computer has also an own address. The addresses are allocated as described in  Chapter 5.2.

The burette TITRONIC® 300 receives commands from a PC at the interface 1 (USB- B) if the computer knows the address. It also sends the answer via this interface. If the address of the incoming command does not match the device address, the complete command will be forwarded to interface 2. Interface 2 is connected to interface 1 of another device. This device checks the address as well and reacts to the command as the first TITRONIC® 300 did before.

All information (data strings) which arrive at interface 2 of the burette TITRONIC® 300 will immediately be send to the computer via interface 1 (or USB-B interface). Thus, the computer receives the data of all devices. In practice it is possible to connect up to 16 devices to one computer- (PC-) interface.

8 Maintenance and Care of the TITRONIC® 300 Piston Burette

The preservation of the proper functioning of the piston burette requires testing and maintenance work to be performed on a regular basis.

Regular inspections are essential prerequisites for the correctness of the volume and the proper functioning of the piston burette.

The accuracy of the volume is determined by all chemicals-carrying components (piston, cylinder, valve, titration tip and hoses). These parts are subject to wear and tear, i.e. zthey are or wearing parts, respectively. The piston and cylinder are subject to particular strain, hence they require special attention.

Heavy strain:

Use of e.g. concentrated solutions, reagents and chemicals (> 0,5 mol/L); chemicals attacking glass, such as fluorides, phosphates, alkali solutions; solutions with a tendency to crystallising out; Fe (III) chloride solutions; oxidising and corroding solutions such as iodine, potassium permanganate, Cer (III), Karl-Fischer titration agent, HCl; solutions with a viscosity of > 5 mm2/s; frequent, or even daily use.

Normal strain:

Use of solutions, reagents and chemicals (up to 0.5 mol/l) which do not attack glass, crystallise out or corrode.

Interrupted use : If the dosing system is not in use for more than two weeks, we recommend emptying and cleaning the glass cylinder and all hoses [6]. This applies in particular under the operating conditions referred to in

the “Heavy strain” section. If this recommendation is not adhered to, the piston of the valve may

become leaking, this may result in damage to the piston burette. If the liquid is left within the system, you will also have to reckon with corrosion and an alteration of the solutions used over time, which includes e.g. crystallisation. Considering that as of the state of the art there are no plastic hoses available for the use in titration equipment which would be perfectly free of diffusion phenomena, particular attention is to be paid to the range of the hose lines.

We recommend the following inspection and maintenance work

Simple cleaning:

 Wiping off splashed chemicals from the outer surface. [1]

Verification of the volume according to ISO 8655:

 Perform basic cleaning  Inspection according to ISO 8655 Part 6 or Part 7. [9]

Semi-annually

Annually

Please note: Depending on the respective application, there may be different specifications for the entirety of the inspection and maintenance work to be performed. The individual intervals may be extended if no complaints occur, but they will have to be shortened again as soon as any problem has arisen.

103

The inspection of the metrological reliability including maintenance work is offered as a service by SI

Analytics GmbH (including a manufacturer’s certificate, if so ordered). For this purpose, the titration

device is to be sent in to SI Analytics GmbH. Detailed description of the inspection and maintenance work:

[1] Wipe off using a soft cloth (and some water with a normal household detergent). [2] Leaking connections can be identified by moisture or crystals at the threaded connections of

the hoses, at the sealing lips of the piston inside the dosing cylinder or at the valve.

[3] If any liquid becomes visible below the first sealing lip, it has to be checked at short timely

intervals whether any liquid will build up under the second sealing lip, too. In this case both the piston and the glass cylinder have to be replaced immediately. It is easily possible that in operation small liquid droplets build up under the first sealing lip, but they may also disappear again. This phenomenon alone is no reason for replacement.

[4] The valve has to be removed from its housing for inspection. In this process, the hoses remain

connected to the valve. Please check for moisture underneath the valve. When reinserting the valve, please make sure that the small cam at the rotating axis is fitted into the corresponding groove again.

[5] The titration tip must be free of sedimentation or crystals which might obstruct the dosing

process or falsify the results.

[6] Remove the cylinder, take the valve out of the valve housing, unscrew the hoses and then

rinse all parts carefully with distilled water. For the assembly of the cylinder, hoses and other parts of the interchangeable unit, please refer to the operating instructions.

[7] Dose one burette volume, then refill. Air bubbles will gather at the tip of the cylinder and in the

titration hose where they can be detected easily. If bubbles become visible, please re-tighten all connections finger tight, and then repeat dosing. If air bubbles still remain within the system, [6] please check the valve and replace the hose connections. The air bubbles may also occur at the interface between the sealing lip of the piston and the cylinder. If a reduction of the filling speed will not do, the dosing unit has to be replaced.

[8] Check the electrical plug contacts for corrosion and mechanical damage. Defective parts have

to be repaired or replaced by new parts.

[9] Please refer to the application “Burette inspection according to ISO 8655 Part 6”.

9 Storage and transportation

If the TITRONIC® 300 Piston Burette or the interchangeable units have to be stored over some time, or to be dislocated, the use of the original packing will be the best protection of the devices. However, in many cases this packing will not be available anymore, so that one will have to compose an equivalent packaging system. Sealing the lower section in a foil is hereby recommended.

The devices should be stored in a room with a temperature between +10 and +40°C, and the (relative) humidity of the air should not exceed 70 %.

If the interchangeable have to be stored over some time, or to be dislocated, the fluids inside the system, especially aggressive solution have to be removed (please refer also to chapter 8. „Maintenance and Care of the TITRONIC® 300 Piston Burette”).

10 Recycling and Disposal

The present piston burette and its packaging are manufactured as far as possible from materials which can be disposed of environmental-friendly and recycled in a technically appropriate manner. Please note: The main printed board carries a lithium battery. Batteries should not to be disposed of with the normal domestic waste. They will be taken back and recycled or disposed of properly by the manufacturer at no cost. Should you have any questions regarding disposal, please contact SI Analytics.
