1 Introduction
1.1 Instrument description
The 876 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. The remote connector enables the integration of the instrument
in a Metrohm automation system.
1.1.1 Dosing modes
The following dosing modes are supported:
￭ DOS
Manual dosing.
￭ XDOS
Fixed volume dosing, with freely selectable dosing criteria.
1 Introduction
1.1.2 Connectors
The instrument is equipped with the following connectors:
￭ MSB connector (Metrohm Serial Bus)
￭ USB (OTG) connector
￭ Remote connector
For connecting a stirrer and an 805 Dosimat for tandem dosings.
The 6.2151.100 adapter allows you to connect, for example, a printer,
a USB memory stick or a USB keyboard. A printer can also be connected directly with the 6.2151.120 cable.
For connecting a Manual Dosing Controller, a Titrino plus or a sample
changer.

The present instrument is suitable for dosing chemicals and flammable solvents. The usage of the 876 Dosimat plus therefore requires that the user
has basic knowledge and experience in the handling of poisonous and
caustic substances. Knowledge with respect to the application of the fire
prevention measures prescribed for laboratories or production plants is
also mandatory.

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.
Figure 6
When a 6.2151.020 USB cable is used, then the 6.2148.030 RS-232/USB
Box can be connected to the 876 Dosimat plus by means of a USB hub or
a 6.2151.100 adapter (see Chapter 3.5, page 11).

6.2151.100
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 876 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.
Figure 7
Connecting USB devices
Caution
Switch the instrument off before connecting or disconnecting a USB
device or a USB stick.
The 876 Dosimat plus can only recognize the device immediately after
switching on.
The following devices can be operated directly on the USB connector
with the 6.2151.100 adapter:
￭ USB sticks (for the backup or storing of methods)
￭ 6.2147.000 numerical USB keypad
￭ 6.2148.030 RS-232/USB Box (for connecting balances or for the
RS-232 remote control)
￭ USB hub (with or without an own power supply)
The 6.2147.000 numerical USB keypad serves for comfortable numerical input and for navigating in the dialog. In addition, it provides two USB
connectors. Connect additional USB devices to the keypad.

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 876 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 6.2147.000
numerical keypad or to a USB hub:
￭ Printer (with USB connector, use the 6.2151.020 connecting cable)
￭ Barcode reader (with USB cable)
￭ Mouse (PC mouse with USB cable, for navigating in the dialog)
￭￭￭￭￭￭￭￭￭￭￭￭￭￭￭￭￭￭￭￭￭￭
The following devices can only be connected to a USB hub:
￭ PC keyboard (with USB cable, for the comfortable input of letters and
numbers)
￭ Keypad with numerical keypad (with USB cable)
If you wish to connect several different instruments without own
power supply, then you must possibly use a USB hub with own power
supply (self powered). The USB (OTG) connector of the 876 Dosimat plus
is not designed for supplying power to several devices with elevated electricity requirements.
Also observe the instructions in chapter 8.4, page 53.
