1 Overview

1.1 Oxi 3310 IDS (Oxi 3315) meter

The Oxi 3310 IDS (Oxi 3315) compact digital precision meter enables you to

perform oxygen (D.O.) measurements quickly and reliably.

The Oxi 3310 IDS (Oxi 3315) provides the maximum degree of operating

comfort, reliability and measuring certainty for all applications.

The Oxi 3310 IDS (Oxi 3315) supports you in your work with the following func-

tions:

 Automatic sensor recognition

 Electronic access control

 Data transmission via the USB interface (USB-B).

1.2 Sensors

A measuring system ready to measure consists of the Oxi 3310 IDS (Oxi 3315)

meter and a suitable sensor.

Suitable sensors are WTW

IDS oxygen sensors.

1.2.1 IDS sensors

IDS sensors

 support the automatic sensor recognition

 show only the settings relevant to the specific sensor in the setting menu

 process signals in the sensor digitally so that precise and interference-free

measurements are enabled even with long cables

 facilitate to assign a sensor to a measured parameter with differently colored

couplings

 have quick-lock couplings with which to fix the sensors to the meter.

Sensor data from

IDS sensors

IDS sensors transmit the following sensor data to the meter:

 SENSOR ID

– Sensor name

– Sensor series number

 Calibration data

– Calibration date

– Calibration characteristics

– Calibration interval

– Calibration history of the last 10 calibrations

The calibration data are updated in the IDS sensor after each calibration pro-

cedure. A message is displayed while the data are being updated in the sensor.

1.2.2 Automatic sensor recognition

The automatic sensor recognition for IDS sensors allows

 to operate an IDS sensor with different meters without recalibrating

 to assign measurement data to an IDS sensor

– Measurement datasets are always stored and output with the sensor

name and sensor series number.

 to assign calibration data to an IDS sensor

– Calibration data and calibration history are always stored and output with

the sensor name and sensor series number.

 to hide menus automatically that do not concern this sensor

Note

In the measured value display, you can display the sensor name and

series number of the selected sensor with the [Info] softkey. You can

then display all further sensor data stored in the sensor with the [More]

softkey.

Oxi 3310 IDS (Oxi 3315) Overview

ba75944e02 10/2014 9

To be able to use the automatic sensor recognition, a meter that supports the

automatic sensor recognition (e.g. Oxi 3310 IDS (Oxi 3315)) and a digital IDS

sensor are required.

In digital IDS sensors, sensor data are stored that clearly identify the sensor.

The sensor data are automatically taken over by the meter.

2 Safety

2.1 Safety information

2.1.1 Safety information in the operating manual

This operating manual provides important information on the safe operation of

the meter. Read this operating manual thoroughly and make yourself familiar

with the meter before putting it into operation or working with it. The operating

manual must be kept in the vicinity of the meter so you can always find the infor-

mation you need.

Important safety instructions are highlighted in this operating manual. They are

indicated by the warning symbol (triangle) in the left column. The signal word

(e.g. "CAUTION") indicates the level of danger:

NOTE

indicates a possibly dangerous situation where goods might be damaged

if the actions mentioned are not taken.

2.1.2 Safety signs on the meter

Note all labels, information signs and safety symbols on the meter and in the

battery compartment. A warning symbol (triangle) without text refers to safety

information in this operating manual.

2.1.3 Further documents providing safety information

The following documents provide additional information, which you should

observe for your safety when working with the measuring system:

• Operating manuals of sensors and other accessories

• Safety datasheets of calibration or maintenance accessories (such as buffer

solutions, electrolyte solutions, etc.)

WARNING

indicates a possibly dangerous situation that can lead to seri-

ous (irreversible) injury or death if the safety instruction is not

followed.

CAUTION

indicates a possibly dangerous situation that can lead to

slight (reversible) injury if the safety instruction is not fol-

lowed.
