Temp. adjustment -1.5 K ... +1.5 K The temperature compensation enables the

temperature display to be balanced (shifting of the zero point by ±1.5K). Notes:

 Due to the thermal capacity of the sensor,

it is necessary to place it in a container with at least 2 liters of water.

 Leave the sensor in this container for at

least 15 minutes while stirring occasionally until the balancing can be performed. With temperature differences between the water and sensor > 10 °C, leave the sensor for at least 1 hour in this container while stirring occasionally until the balancing can be performed.

4.2 Function check and user calibration

4.2.1 General information

70x IQ ... is factory calibrated. In the recommended application (see section 1.3 R measuring characteristics of the sensor cap remain stable for the specified service life. Thus, a user calibration is not usually required.

A function check or user calibration can be useful in the following special cases:

 If the measured values appear to be implausible and it is assumed

that the service life of the sensor cap is over

 Routinely within the framework of the company quality assurance. Select one of the following two variants depending on the air tempera-

ture at the calibration site:  With air temperatures over 5 °C, the function check and user calibra-

tion ideally take place in water vapor-saturated air. To do so, position the sensor approx. 2 cm above a water surface, for example in a narrow bucket or similar container with water. The membrane must be clean and dry for this.

2cm

 With air temperatures under 5 °C we recommend performing the

function check and user calibration not in air but in air-saturated water that has a higher temperature. You obtain air-saturated water by pouring water several times in and out of two vessels so that it sparkles.

4.2.2 Function check

A function check is the simplest way to determine whether the sensor needs to be cleaned or user-calibrated.

Principle The function check can either be done in water vapor-saturated

air or in air-saturated water (see C

4.2.3 User calibration

Principle The user calibration can either be done in water vapor-saturated

air or in air-saturated water (see C

HECK OR CALIBRATION MEDIUM on

page 4-1). With the calibration procedure, the relative slope of the sensor is determined. The calibration is evaluated based on the relative slope and the intensity (successful <-> unsuccessful).

The result of the user calibration is stored in the calibration record and calibration history respectively and can be viewed afterwards (see respective IQ S

ENSORNET system operating manual).

We want to point out that the factory calibration of the membrane is highly precise due to the IQMC technology. If you still want to carry out a user calibration, influences due to environmental conditions have to be taken into account.

Steps Generally, a user calibration on the IQ S

lows. System specific details are given in the respective IQ S system operating manual.

1 Switch to the measured value display with <M> and select the

FDO

70x IQ ... sensor.

2Press <C>.

The next step switches on the maintenance condition for the

sensor. A corresponding message appears on the display. 3 Confirm the note with <OK>.

The maintenance condition is active. 4 Select the CALIBRATION procedure and press <OK>. 5 Put the sensor into the calibration position (water vapor-satu-

rated air or air-saturated water - see section 4.2.1). 6Press <OK>.

The sensor determines the calibration data. The display

switches to the measured value display. The CAL indicator

flashes instead of the main measured value. At the same time,

the momentary relative slope flashes as the secondary mea-

sured value. The process ends automatically as soon as the

measured values meet the criterion for the stability control.

With a great temperature difference between the sensor and

the environment this may take a while. Subsequently, the main

measured value and temperature are displayed.

4.2.5 Reactivating previous calibration data

The FDO

70x IQ ... enables you to reactivate the last valid user calibration or the factory calibration. Thus you can immediately go on measuring if a calibration procedure failed or you suspect that the calibration conditions were not optimally met.

Reactivating old calibration data is only a temporary solution. Please take into account that the sensor might thus possibly provide incorrect measured values. Please make sure the sensor works correctly by carrying out a function check and/or recalibration.

Reactivating calibration

1 Open the setting table (see section 3.4). 2 In the Calibration menu item, sele ct the User calibration or Fac-

tory calibration setting and then quit the setting table with Save and quit.

5.1 General maintenance instructions

WARNING

Chemical or biological hazard. Contact with the sample can be harmful to the user. Depending on the type of sample, suitable protective measures must be taken (protective clothing, goggles, etc.).

Maintenance condition We recommend to switch on the maintenance condition each time the

sensor is taken out of the measuring position. This avoids unwanted reactions of linked outputs. For more detailed information on the maintenance condition please refer to the respective IQ S operating manual.

ENSORNET system

We do not recommend unscrewing the sensor from the sensor connection cable in order to do maintenance work. Otherwise, moisture and/or dirt can get into the plug connection where it can cause contact problems.

If you would like to disconnect the sensor from the sensor connection cable, please note the following points:

 Before disconnecting the sensor from the SACIQ (SW) sensor con-

nection cable, the sensor has to be cleaned on the outside (see section 5.4.1).

 Unscrew the sensor from the SACIQ (SW) sensor connection cable.

 Place a protective cap on the sensor plug head connector and on

the SACIQ (SW) sensor connection cable each time so that no moisture or dirt can get on the contacting surfaces.

 In corrosive environments, close the socket of the sensor connec-

tion cable with the screwable SACIQ-Plug when it is dry in order to protect the electrical contacts from corrosion. The protective plug is available as an accessory (see section 5.5 R

ACCESSORIES). It is included in the standard scope of delive ry of the

SACIQ SW sensor connection cable.

5.2 Handling of the sensor cap

Despite its exterior robustness, the sensor is an optical high precision instrument. Therefore, special care should be taken when doing any maintenance or cleaning work:

 Dirt and moisture under the sensor cap can affect the functioning

and shorten the service life of the sensor cap. Therefore, make sure the working environment is clean and dry prior to removing the sensor cap.

 Please do not touch the outer sensor membrane with your fingers.

Touch the sensor cap at the sides only (shaded area in figure on the left).

 Avoid any great mechanical stress of the sensor membrane (pres-

sure, scratches).

 Exposure to light, particularly daylight of the interior of the sensor

cap will, by-and-by, affect the measurement characteristics and shorten the service life of the sensor cap. Therefore, the interior of the sensor cap should not be exposed to direct sunlight. Avoid any exposure to light that exceeds the extent required for necessary maintenance and cleaning activities. Store dismantled sensor caps in a light-protected environment only.

Removing the sensor

cap

5.3 Exchanging the sensor cap

1 Pull the sensor out of the sample. 2 Clean the outside of the sensor (see section 5.4.1). 3 Unscrew the fixing ring from the sensor by hand. 4 Thoroughly clean and dry the sensor head once again. 5 Grasp the sensor cap on the sides (arrows in figure on the left)

and remove it by pulling it away from the sensor in a straight upward direction.

NOTICE

Do not push any tools or other sharp objects between the sealing surfaces. This might damage the sealing surfaces.

6 Check the front surface of the sensor for absolute cleanness

and clean it if necessary (see section 5.4.1). 7 Thoroughly clean the thread of the fixing ring. 8 Place the new sensor cap on the sensor so that the tempera-

ture sensor fits into the hole inside the sensor cap (see figure

opposite). 9 Put the fixing ring on the sensor head and screw it tight by

hand.

5.4 Cleaning the sensor

5.4.1 Exterior cleaning

Dirt on the sensor can affect the measuring characteristics. Biological deposits for example, consume oxygen and can, when occurring on the sensor cap membrane, impair the responding behavior and cause values that are too low. Therefore, we recommend regular visual inspections and exterior cleaning as necessary.

Pay attention to the following points for cleaning:  First, thoroughly rinse the sensor with tapwater to remove loosely

adhering dirt.

 Rough dirt o n the sensor shaft can be brushed off with a soft brush.

Attention:

Do not use the brush in the area of the sensor membrane.

Risk of damage!

 The sensor cap including the sensor membrane should be wiped

with a soft and moist microfiber cloth.

 In the case of persisting dirt you can add some household wash ing-

up liquid to the tapwater. Attention:

Never use any alcohol for clean-

ing!

 If the are any salt or lime deposits, the sensor can be cleaned with

aqueous citric acid solution (10 % weight percent).

Maintenance, cleaning, replacement parts FDO®70x IQ ...

5.4.2 Interior cleaning of sensor cap and sensor head

If moisture or dirt have penetrated under the sensor cap, e.g. because the sensor cap is damaged, you can make the sensor ready for operation again as follows:

NOTICE

Only use nonabrasive, alcohol-free detergents, as otherwise the optical surfaces could be damaged.

1 Remove the sensor cap (see section 5.3). 2 Clean the sensor head and sensor cap:

– Rinse all inner surfaces with tapwater

– Remove contamination containing fat and oil with warm

water and household washing-up liquid

3 Dry all surfaces with a clean, lint free cloth. A lint-free cloth

such as a microfiber cloth used to clean eyeglasses is suitable.

4 Allow the sensor and sensor cap to dry completely at a dry

location so moisture can evaporate even from corners difficult to access. When doing, so protect the inside of the sensor cap from light.

If the sensor cap is visibly damaged it has to be replaced.
