instrument and accessories are damaged by transportation and whether the accessories
are complete. If any abnormalities are found, please contact our after-sales service
department or regional customer service center, and keep the package for return
processing.
This instrument is an analytical measurement and control instrument with highly
precision.Only skilled,trained or authorized person should carry out installation, setup and
operation of the instrument.Ensure that the power cable is physically separated from the
power supply when connection or repair.Once the safety problem occurs, make sure that
the power to the instrument is off and disconnected.
For example, it may insecurity when the following situations occur:
1) Apparent damage to the analyzer
2) The analyzer does not work properly or provides specified measurements.
3)The analyzer has been stored for a long time in an environment where the temperature
exceeds 70 °C.

2
The analyzer must be installed by professionals in accordance with relevant local
specifications, and instructions are included in the operation manual.
Comply with the technical specifications and input requirements of the analyzer.
Features

Instrument connection
The connection between the instrument and the sensor: the power supply, output signal, relay alarm contact and the
connection between the sensor and the instrument are all inside the instrument, and the wiring is as shown above. The
length of the cable lead fixed by the electrode is usually 5-10 Meters, insert the corresponding label or color wire on the
sensor into the corresponding terminal inside the instrument and tighten it.
