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").

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.

Preparatory steps for comparison measurement with a bypass
Install the measuring arrangement as follows:
1. Secure the flow assembly with the carrier on a pipe (e.g. railing).
On square pipes mount the clamping jaw with the V-notch facing outwards, and facing
inwards on circular pipes,
or position the flow assembly safely.
2. Set the "Bypass - Direct" switch to "Bypass" (Position 1).
3. Using a hose connection adapter (provided in the case) mount the outflow hose on the
"OUT" outlet of the flow assembly (Item 7). Only screw the hose connection adapter
finger-tight into the flow assembly.
4. Using a hose connection adapter mount the medium hose on the "IN 1" inlet of the flow
assembly (Item 4).
5. Seal the "IN 2" inlet (Item 5) with a stopper (provided in the case).
6. Screw the sensor of the calibration kit into the flow assembly (Item 2).
7. In the flow assembly, seal the installation point for the process sensor (Item 3) with a
stopper.

6. Screw the sensor of the calibration kit into the flow assembly (Item 2).
7. Screw the process sensor into the flow assembly (Item 3). For sensors with a G1 process
connection, use the G1 adapter clamp (provided in the case).
3.2.5 Electrical connection
Connecting the calibration kit:
1. Install the measuring cable between the sensor, calibration kit and transmitter (exterior
of the case).
2. In the case of direct comparison measurement:
Install the measuring cable between the process sensor and process transmitter.
3. If a power supply is available, connect the mains cable (exterior of the case).

3.2.6 Comparison measurement
1. Open the medium flow to the flow assembly.
2. Optimize the flow with the regulation valve (Item 6).
Procedure: Close the regulation valve. Now open the regulation valve slowly until the
flow meter (Item 8) is at the upper limit.
3. Switch on the two transmitters. It takes up to 8 seconds until information is displayed
on the transmitter of the calibration kit.
4. In the case of comparison measurement with a bypass: Waiting until the temperature
in the flow assembly has adjusted to match the process temperature (around 30
minutes).
If the temperature difference is < 0.1 °C, you do not need to change any settings on
the transmitter of the calibration kit.
If the temperature difference is > 0.1 °C, set the temperature compensation on both
transmitters to ultrapure water. Setting on transmitter of the calibration kit:
SETUP/Operating mode/Temp.compensation/UPW (NaCl)
Now select the measuring mode again.
5. Vent the flow assembly by unscrewing the sensor of the calibration kit slightly. Tighten
the sensor again as soon as water comes out.
6. Start the measurement.
7. Adjust the process measuring point with the comparison value (see Operating
Instructions of the process transmitter).
8. Disconnect the calibration kit from the power supply.
NOTICE
Water can damage the electrical parts of the calibration kit
‣Empty the flow assembly completely before you put it back in the case.

4.1 Cleaning
WARNING
!
The device is energized.
Performing cleaning work on live parts can result in injury or death.
‣Disconnect the case from the power supply before commencing the cleaning tasks.
Clean the front of the housing of the transmitter and the case with commercially available
cleaning agents.
NOTICE
Cleaning agents can damage the surface of the device
Never use any of the following to clean the device:
‣Concentrated mineral acids or bases
‣Benzyl alcohol
‣Methylene chloride
