Introduction 3SevenCompact™ Duo S213

1 Introduction

Thank you for purchasing this METTLER TOLEDO instrument. The SevenCompact Series is not only a new

generation of intuitive and easy-to-operate bench meters for reliable measurements, they also provide extra

security against mistakes and support your workflow in the laboratory.

Mistakes can be reduced to a minimum because of the following characteristics:

• ISM

(Intelligent Sensor Management) technology: the meter automatically recognizes the sensor and

transfers the latest set of calibration data from the sensor chip to the meter. The last five calibrations as

well as the initial calibration certificate are also stored on the sensor chip. These can be reviewed, trans-

ferred and printed. ISM

provides additional security and helps eliminate mistakes.

• Multi-language graphical user interface on a large 4.3 inch display with intuitive menu guidance,

making the operating instructions primarily a source of reference.

• Expert and Routine mode for the needs of any operator: in the routine mode, the deletion of data is

prevented and changing those settings that would potentially jeopardize the collection of reliable results,

such as measurement settings, are blocked. This provides extra security for routine daily work. Skilled

workers are advised to employ the GLP mode to enjoy the instruments’ powerful full functional range.

This instrument supports the workflow of a modern laboratory in all stages of the data collection and

archiving process:

• The uPlace™ electrode arm can be operated with one hand and moves perfectly straight up and down

to bring the electrode in the perfect position for the best measurement performance. This allows faster

measurements and poses less risk to tip over the sample vessel and/or damage the head of the sensor!

• Only one keypress required: Read starts a measurement and Cal a calibration. It’s so easy!

• Easy switching between the normal view and the uFocus™. The normal view has all the

measurement parameters and IDs on the display to provide you an instant complete overview. In the

uFocus™ only the most important information is shown in large digits, such as measurement value and

temperature. This enables you to focus completely on the measurement, without getting distracted by

information that is not relevant to you.

• Easy toggling with the soft key Mode. Toggle between the various measurement parameters either

before or during a measurement.

• Versatile data archiving options: print data, export data to a USB-stick, or send data to a PC with

EasyDirect pH software! EasyDirect pH allows to store the data electronically almost unlimited and

export them to Excel, or any other comma separated file for further use seamleassly and easy.

• Versatile data entry procedures: Enter sample / user and sensor IDs either directly on the instrument,

or use a barcode reader or USB-Keyboard to increase efficiency.

At METTLER TOLEDO we are committed to providing you instruments of highest quality and we do all we

can to support you in maximizing the lifetime of your instrument:

• IP54 rating – water and dust protection: we have designed our instrument in such way, that it

withstands spray of aqueous solutions on the housing and connections. This not only provides extra

protection, but also allows easy cleaning of the instrument with a damp cloth.

• Rubber plugs and protective cover provide extra security against dust and spills of aqueous solutions.

Just keep the plug attached to the connections and cover the instrument with the transparent protective

cover when not in use.

Have fun and many reliable measurements with our SevenCompact series of pH, Ion and conductivity

meters!

4.1 Scope of delivery

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

SevenCompact™ is delivered with:

• uPlace™ electrode arm

• Sensors (kit version or according to your order)

• Universal AC adapter

• Transparent protective cover

• CD-ROM with Operating instructions 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 Operation14 SevenCompact™ Duo S213

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 contain a live current can lead to injury and death. If the

instrument cannot be shut down in an emergency situations, people can be injured or the

instrument can be damaged.

1 Check the cables and the plug for damage and replace damaged cables and plugs.

2 Ensure that the cables are arranged so that they cannot be damaged or interfere with

the operation.

3 Ensure that the power plug is accessible at all times.

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.

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 Plug the AC adapter into the wall socket.

PUSH

Putting into Operation 15SevenCompact™ Duo S213

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.
