must follow the instructions contained therein.

• Faults at the measuring point may only be rectified by authorized and specially trained

personnel.

Repairs not described in the Operating Instructions provided must be carried out only

directly at the manufacturer's site or by the service organization.

2.2 Intended use

The COL37E oxygen sensor is designed for short-term measurement in laboratory or field

environments.

The oxygen sensor is not intended for continuous measurements and for fixed installation in

the process or in assemblies.

NOTICE

Halogen-containing solvents, ketones and toluene

Halogen-containing solvents (dichloromethane, chloroform), ketones (e.g. acetone,

pentanone) and toluene have a cross-sensitive effect and result in decreased measured values

or, at worst, in the complete failure of the sensor!

‣Use the sensor only in media that are free from halogens, ketones and toluene.

Use of the device for any purpose other than that described, poses a threat to the safety of

people and of the entire measuring system and is therefore not permitted.

The manufacturer is not liable for damage caused by improper or non-designated use.

2.3 Workplace safety

As the user, you are responsible for complying with the following safety conditions:

• Installation specifications

• Local standards and regulations

2.4 Operational safety

Before commissioning the entire measuring point:

1. Verify that all connections are correct.

2. Ensure that electrical cables and hose connections are undamaged.

3. Do not operate damaged products, and protect them against unintentional operation.

4. Label damaged products as defective.

During operation:

‣If faults cannot be rectified:

products must be taken out of service and protected against unintentional operation.

5.1 Calibration and adjustment

The sensor is calibrated and adjusted in the factory prior to delivery and is therefore ready for

immediate use.

Commissioning Memosens COL37E

10 Endress+Hauser

Refer to Operating Instructions BA02002C on the product page (www.endress.com/cml18)

for the measurement, calibration and adjustment of the sensor on the Liquiline Mobile

CML18.

Recommended procedure after replacing a spot cap

First calibrate and adjust the sensor at the zero point and then in the presence of oxygen.

5.1.1 Zero point calibration

The zero point is not so important when working with relatively high concentrations of

oxygen. In these types of application, a zero point calibration is required only after the spot

cap has been replaced.

However, once oxygen sensors are used at low concentrations and in the trace range, they

must also be calibrated at the zero point.

Zero point calibrations are demanding as the ambient medium - usually air - already has a

high oxygen content. This oxygen must be excluded for zero point calibration of the sensor.

A calibration with the COY8 zero-point gel can be used for this purpose:

The COY8 oxygen-depleting gel creates an oxygen-free medium for zero point calibration.

Prior to sensor zero point calibration, check the following:

• Is the sensor signal stable?

• Has the adjustment time of 30 min - 40 min for the COY8 zero-point gel elapsed?

• Is the value displayed plausible?

1. If the sensor signal is stable:

Calibrate the zero point.

2. If necessary:

Adjust the sensor by accepting the calibration data.

If the oxygen sensor is calibrated too early, this can result in an incorrect zero point.

Rule of thumb: operate the sensor for at least 30 min in the zero-point gel.

Follow the instructions in the kit documentation enclosed with the COY8 zero-point gel.

5.1.2 Calibration in air with 100% rH

1. Remove the sensor from the medium.

2. Clean the outside of the sensor carefully with a damp cloth.

3. Suspend the sensor just above the surface of the water. Use the calibration bottle

provided for this purpose.

Do not immerse the sensor.

4. Allow a temperature compensation time of approx. 20 minutes for the sensor in the

ambient air. Make sure that the sensor is not exposed to any direct ambient effects

(direct sunlight, drafts) during this time.
