4 Putting into Operation

4.1 Scope of delivery

Unpack the instrument and check the scope of delivery. Keep the calibration certificate in a safe place. Seven-

Compact™ is delivered with:

• uPlace™ electrode arm

• Sensors (kit version only)

• Universal AC adapter

• Transparent protective cover

• CD-ROM with Reference Manual and User Manual (English, German, French, Italian, Spanish, Portuguese,

Polish, Russian, Chinese, Japanese Korean, Thai)

• User Manual (print version, English, German, French, Italian, Spanish, Portuguese, Polish)

• Declaration of conformity

• Calibration certificate

4.2 Mounting uPlace™ electrode arm

The electrode arm can be used as stand alone or it

can be attached to the instrument on the left or right

side, according to your preferences. The height of the

electrode arm can be varied by using the extension

shaft part. Use the wrench to attach the extension

part .

Assembly of the electrode arm

1 Use the wrench to attach the base to the electrode

arm by tightening the screws. The electrode arm

can now be used in the stand alone mode.

Putting into Operation 13SevenCompact™ S210

2 Then insert the foot of the meter to the arm base

and shift the meter in the direction of the arrow to

make the foot fit.

3 Use the lock screw to attach the meter to the base

of the arm.

4.3 Installing power supply

WARNING

Danger of death or serious injury due to electric shock!

Contact with parts that carry a live current can lead to death or injury.

1 Only use the METTLER TOLEDO AC adapter designed for your instrument.

2 Keep all electrical cables and connections away from liquids and moisture.

3 Check the cables and the plugs for damage and replace damaged cables and plugs.

NOTICE

Danger of damage to the AC adapter due to overheating!

If the AC adapter is covered or in a container, it is not sufficiently cooled and overheats.

1 Do not cover the AC adapter.

2 Do not put the AC adapter in a container.

The instrument is operated using an AC adapter. The AC adapter is suitable for all supply line voltages ranging

from 100...240 V AC ±10% and 50-60 Hz.

PUSH

1 Insert the correct connector plug into the AC adapter

until it is completely inserted.

2 Connect the cable of the AC adapter with the DC socket

of the instrument.

3 Install the cables in such a way that they cannot be

damaged or interfere with operation.

Putting into Operation14 SevenCompact™ S210

4 Insert the plug of the AC adapter in a power outlet that is easily accessible.

ð To remove the connector plug, push the release button and withdraw the connector plug.

4.4 Connecting sensors

When connecting a sensor, make sure that the plugs are properly inserted. If you are using a sensor with a

built-in temperature probe or a separate temperature probe, connect the second cable to the ATC socket.

Example

− Connect a pH sensor to the BNC plug and if a temperature probe is integrated, connect the RCA (chinch)

plug to the ATC input.

- or -

Connect a conductivity probe to the conductivity input, a temperature probe is always built in and does not

need to be connected seperatly. If you have a digital sensor connect it to the digital input.

ISM

sensor

When connecting an ISM

sensor to the meter, one of the following conditions have to be met for the calibration

data to be transferred automatically from the chip of the sensor into the meter and is used for further

measurements. After attaching the ISM

sensor ...

• The meter must be switched on.

• (If the meter is already switched on) the Read key is pressed.

• (If the meter is already switched on) the Cal key is pressed.

We strongly recommend you to switch off the meter when disconnecting an ISM sensor. In doing so, you make

sure that the sensor is not removed while the instrument is reading data from or writing data to the ISM-chip of

the sensor.

The ISM icon appears on the display and the sensor ID of the sensor chip is registered and appears on the

display.

The calibration history, the initial certificate and the maximum temperature can be reviewed and printed in the

data memory.

4.5 Switching the instrument on and off

Switching on

− Press and release On/Off to switch on the instrument.

ð The firmware version, the serial number and the current date are displayed for a few seconds. After that

the instrument is ready for use.

Switching off

− Press and hold the On/Off key until the instrument switches to standby mode.

Note

• In the standby mode, the control circuit for the On/Off switch is energized. The rest of the instrument is no

longer energized.

4.6 Connectivity

Thanks to the plug & play capability, USB-sticks, barcode reader and printers are detected automatically.

Connection Use

RS232 interface RS-Printers

USB B interface

EasyDirect pH PC Software

USB A interface USB-printer, USB barcode reader
