￭￭￭￭￭￭￭￭￭￭￭￭￭￭￭￭￭￭￭￭￭￭ 1 Introduction 1 Introduction 1.1 Instrument description The 865 Dosimat plus is a universally utilizable dosing instrument. Methods can be generated and stored under a new name. When a USB memory stick is connected as an external storage medium, then the methods can be exported to that USB memory stick. This function makes it possible for you to copy methods quickly and easily from one instrument to another.
￭￭￭￭￭￭￭￭￭￭￭￭￭￭￭￭￭￭￭￭￭￭ 1.2 Intended use 1.2 Intended use The 865 Dosimat plus is designed for use in laboratories and production plants. Its main area of application is the precise dosing of liquids. This includes simple dosing according to specific criteria, the preparing of solutions, the pipetting of liquid samples and manual titrations. The present instrument is suitable for dosing chemicals and flammable solvents.

Keep this packaging, as only this ensures safe transportation of the instrument. 3.1.2 Checks Immediately after receipt, check whether the shipment has arrived complete and without damage by comparing it with the delivery note. 3.1.
￭￭￭￭￭￭￭￭￭￭￭￭￭￭￭￭￭￭￭￭￭￭ 3.3 Connecting the Manual Dosing Controller Caution Make sure that the flat side of the plug matches the marking on the socket. 3.3 Connecting the Manual Dosing Controller Figure 5 Connecting the Manual Dosing Controller The Manual Dosing Controller is connected to the remote connector on the rear of the instrument. 3.4 Connecting a balance Balances are equipped with a serial RS-232 interface as a rule. To connect a balance, you require a 6.2148.030 RS-232/USB Box.
￭￭￭￭￭￭￭￭￭￭￭￭￭￭￭￭￭￭￭￭￭￭ 3 Installation The parameters for the RS-232 interface on the instrument must match those on the balance (see "Editing the COM1 settings", page 35). Additionally consult the user manual of the balance. 3.5 Connecting a keyboard, printer and other USB devices The 865 Dosimat plus has a USB (OTG) connector. Use the provided 6.2151.100 adapter USB MINI (OTG) - USB A for connecting USB devices as e.g. printers, keyboards or USB sticks, see the following figure. 6.2151.
3.5 Connecting a keyboard, printer and other USB devices ￭￭￭￭￭￭￭￭￭￭￭￭￭￭￭￭￭￭￭￭￭￭ Note Most of the USB devices need a so-called hub in order to work correctly. A USB hub is a distributor to which several USB devices can be connected. USB hubs are available in specialty stores in a number of different models. The USB (OTG) connector of the 865 Dosimat plus has no such hub. The 6.2147.000 numerical USB keypad has a USB hub and two USB connectors. The following devices can only be connected to a 6.2147.

A result can be calculated automatically from the dosed volume and a result report can be printed out. Different calculation variables can be defined in advance as parameters. The parameters as a whole can be saved as a method and then later used where required.
￭￭￭￭￭￭￭￭￭￭￭￭￭￭￭￭￭￭￭￭￭￭ 6.1 Manual dosing (DOS) The [FILL] key can be used at the end of a determination to initiate the filling of the dosing cylinder. This automatically initiates the calculation of the result and the printing out of a result report, if the appropriate settings have been made; see following chapters. The result of the calculation is shown under the volume display. The result and the dosing volume can be deleted by pressing the [FILL] key once more. 6.1.
￭￭￭￭￭￭￭￭￭￭￭￭￭￭￭￭￭￭￭￭￭￭ 6 Parameters and dosing modes Dosing ramp The dosing ramp is a delay in the dosing rate at the time of the start of a dosing step. It is advantageous primarily for manual titrations with indicator, when small volume steps are to be dosed before the equivalence point. The selectable delay time determines after which amount of time (in seconds) the defined dosing rate is to be reached. 0 ... 10 s 0s Range Default value mL/min 90 60 30 2 Figure 17 6.1.
￭￭￭￭￭￭￭￭￭￭￭￭￭￭￭￭￭￭￭￭￭￭ 6.1 Manual dosing (DOS) Note If a solution has been selected under Parameters, then the corresponding titer and the concentration will be read out from the solution data under System ▶ Solutions and used for calculations.

￭￭￭￭￭￭￭￭￭￭￭￭￭￭￭￭￭￭￭￭￭￭ 6.2 Extended dosing (XDOS) Selection Default value off | on off on If the pulse control is activated, dosing is controlled via the remote interface. The [GO] key starts the pulse control and is deactivated afterwards. Autostart at power-on If this setting is activated, the pulse control is already activated when switching on the instrument or when loading the method. Manually starting the corresponding method is therefore not necessary.

Performing a dosing Pressing the [GO] key causes the dosing to run automatically. Three dosing criteria are applied for this process. The specified dosing criteria are observed in all cases. The dosing criterion that is not defined in a specific case (volume, time or dosing rate) is calculated by the instrument and shown on the display.
￭￭￭￭￭￭￭￭￭￭￭￭￭￭￭￭￭￭￭￭￭￭ 6.2 Extended dosing (XDOS) Single Dosing with one instrument. Tandem Dosing with two Dosimats. Tandem operation An 805 Dosimat is connected to the MSB connector of the 865 Dosimat plus for tandem operation. Note Two exchange units with the same cylinder size must be used for tandem operation.

The file name of the TXT file is constructed as follows: PC_LIMS_ReportID1-YYYYMMDD-hhmmss.txt.
￭￭￭￭￭￭￭￭￭￭￭￭￭￭￭￭￭￭￭￭￭￭ 7 Handling and maintenance 7 Handling and maintenance 7.1 General The 865 Dosimat plus requires appropriate care. Excess contamination of the instrument may result in malfunctions and a reduction in the service life of the sturdy mechanics and electronics of the instrument. Severe contamination can also have an influence on the measured results. Regular cleaning of exposed parts can prevent this to a large extent. Spilled chemicals and solvents must be removed immediately.

￭￭￭￭￭￭￭￭￭￭￭￭￭￭￭￭￭￭￭￭￭￭ 8.2 Stirring rate 8.2 Stirring rate The stirring rate can be adjusted in steps of –15 to +15. The approximate rotational speed can be calculated with the following formula: Rotational speed/min (r/min) = 125 · stirring rate Example: Stirring rate set: 8 Rotational speed in rpm = 125 · 8 = 1000 r/min 2000 1500 1000 500 -15 Figure 19 8.
