1 Safety instructions
1.1 Designated use
Conducal CLY421 is a calibration kit designed for checking and calibrating conductivity
measurements in the pure water and ultrapure water range. With the calibration kit, process
measuring devices can be calibrated and checked without the need for calibration solutions.
Only the specific conductivity or the resistivity is determined when the calibration kit is
operated.
Any other use than the one described here compromises the safety of persons and the entire
measuring system and is therefore not permitted.
The manufacturer is not liable for damage resulting from improper or non-designated use.
1.2 Installation, commissioning and operation
Note the following points:
• Installation, commissioning, operation and maintenance of the measuring system must
only be carried out by trained technical personnel.
The technical personnel must be authorized to perform the tasks by the owner-operator.
• The device may only be operated on a low-voltage network that is protected by a circuit
breaker.
• The technical personnel must have read and understood these Operating Instructions and
must follow the instructions they contain.
• Before commissioning the entire measuring point, check that all the connections are
correct. Ensure that electrical cables and hose connections are not damaged.
• Do not operate damaged products. Secure them against unintentional commissioning.
Mark the damaged product as defective.
• Faults at the measuring point may only be rectified by authorized and specially trained
personnel.
• If faults cannot be rectified, the products must be taken out of service and secured against
unintentional commissioning.
• Repairs not described in these Operating Instructions may only be carried out directly at
the manufacturer's or by the Service Organization.
• The cover plate, transmitter and charger may not be opened.
• Connection of the system must only be carried out by electrically instructed persons.
1.3 Operational safety
The system is designed to meet state-of-the-art safety requirements, has been tested, and
left the factory in a condition in which it is safe to operate.
The applicable regulations and European standards have been taken into account.
As the user, you are responsible for complying with the following safety conditions:
• Installation specifications
• Local standards and regulations
• Mechanical hazard due to transport and handling
1.4 Notes on safety conventions and icons
The structure, signal words and color coding of warning information are in compliance with
ANSI Z535.6 specifications ("Product safety information in product manuals, instructions
and other collateral materials").

2.1 Nameplate
The following information is provided on the nameplate:
• Manufacturer details
•Ordercode
• Extended order code
• Serial number
• Operating conditions
• Safety information symbols
Compare the order code on the nameplate with your order.
2.2 Scope of delivery
The delivery comprises:
• 1 Calibration kit in the version ordered
•1SetofOperatingInstructions for Conducal CLY421
• 1 Certificate of calibration
If you have any questions, please contact your supplier or your local sales center.
2.3 Certificates and approvals
Declaration of Conformity
The product meets the requirements of the harmonized European standards.
As such, it complies with the legal specifications of the EC directives.
The manufacturer confirms successful testing of the product by affixing to it the 4mark.
Factory calibration certificate
The Conducal CLY421 calibration kit is calibrated and adjusted at the factory. With the aid
of a reference system, the CLS15D reference sensor is calibrated precisely in accordance with
the specifications of ASTM Standard 5391-93. In this way, the cell constant and
temperature offset of the sensor are determined and recorded in the factory calibration
certificate.
The certificate, which is created for each individual Conducal CLY421 kit, is enclosed in the
calibration kit.

3.2 Operation
3.2.1 Rechargeable battery
You must charge the lithium ion battery before you connect the calibration kit.
1. Insert the round connector of the power supply cable into the power supply connection
on the right-hand side of the case.
2. Insert the mains plug of the power supply cable into the socket.
3. The lithium ion battery will now be charged.
The light emitting diode on the charger can indicate two charge states:
•Orange: The battery is being charged.
•Green: The battery is fully charged.
It can take several hours to charge the battery.

Conducal CLY421 Device description and operation
Endress+Hauser 9
The transmitter of the CLY421 is already configured. You just have to switch on the
transmitter. The transmitter displays the measured value after a few moments.
You need only switch on temperature compensation if the difference in temperature
between the calibration sensor and the process sensor is > 0.1 °C. This is described in
the "Comparison measurement" section.
3.2.3 Measuring arrangements
The calibration kit can be used for two measuring arrangements:
• Comparison measurement with a bypass
• Direct comparison measurement

Comparison measurement with a bypass
With this arrangement, it is important to make sure that the composition of the medium and
the temperature at the process measurement point and comparison measurement point are
the same. This is ensured by:
• Using short hose connections
• Wait until the temperature in the flow assembly adjusts to match the process temperature.
