Important Safety Information
Please read and observe the following:
Please read this entire manual before unpacking, installation and operation, with particular
attention to all danger warnings and precautions. Failure to do so may result in damage to
the instrument or personal injury to the operator due to misuse. Do not install or use the
instrument by any means other than those specified in this manual.
•After opening the analyzer case, the user may touch the instrument supply voltage.
Please make sure to disconnect the power, before you open the analyzer cases. Analyzer
housing assembly only low voltage, the operation is safe.
•The analyzer must be installed in accordance with relevant local codes and the
professional and technical personnel, to comply with the analyzer's technical
specifications and input ratings. If you are not sure which of the main power lines is the
zero line, use a double-blade switch to disconnect the analyzer.
•As soon as a problem occurs with the analyzer, disconnect the analyzer from power to
prevent any unintentional operation that could result in damage to the instrument. For
example, it may be in an unsafe state when the following situations occur:
(1) The analyzer appears visibly damaged;
(2) Analyzer fails to operate properly or provide the intended measurements;
(3) Analyzer has been stored for a long period of time at temperatures over 70°C
environment.
•Wiring or repair should be done by professionals, and only the power-off analyzer
should be operated.

Note: Please read this operation manual thoroughly before installation to
avoid damage to the instrument due to wrong wiring.
——— Chapter 2 ———
Unpacking
After unpacking, it is recommended that the shipped cardboard boxes and packing
materials be saved for instrument storage or reshipment. Inspect equipment and packing
materials for signs of damage during shipment. If there are signs of damage, immediately
notify the person delivering the shipment.
Part 2 Installation
• Please choose a well-ventilated location to install the instrument to avoid direct
sunlight.
• The electrode signal transmission must use specific cables or cables provided by our
company, and cannot be replaced by random wires.
• When using AC 220V power supply, avoid using three-phase power supply to avoid
power spike interference (if power spike interference occurs, the power supply of the
controller can be separated from the power supply of the control device, so that the
controller uses a separate power supply, or the coil ends of all electromagnetic
switches and power control devices are connected to spike absorbers to eliminate
spikes, such as dosing machines, mixers, etc.).
• It is generally recommended that the controller be accessible to the electrode during
installation.
• Avoid corrosive liquids, or need to protect and isolate the environment.
3.1 Installation Location
Caution:
Analyzer directly exposed to the sun, its operating temperature may exceed its
specified limit temperature, and will reduce the visibility of the display.
☞
The installation location of the meter is:
Unaffected by weather (rain, snow, ice, dust, etc.)
• Clean, dry and with little or no vibration
• Keep away from corrosive liquids
• Within ambient temperature limits（32～140℉or 0～60℃）

This function enables the master (host computer) to obtain the real-time measurement
value of the slave (instrument). The value is specified as a single-precision
floating-point type (that is, occupying two consecutive register addresses), and the
corresponding parameters are marked with different register addresses;
The host can send a command frame to read a single or all data results. The data frame
format is as follows (the data is all in Hex format):
2. Function code details (function code 0×04):
The instrument acts as a slave on the network and supports Modbus RTU
communication protocol.
Data communication is initiated by the host, and the first byte of the transmitted
message is the target slave address. When the first byte is received by all the slaves on
the network, each slave will decode it to determine whether the message is sent to
itself.
The transmission of the RTU message frame must start with a pause interval of at least
3.5 characters. After the last character is transmitted, a pause of at least 3.5 characters
marks the end of the message frame. A new message can start after this pause. In the
transmission process, the entire message frame must be transmitted in a continuous
stream. If there is a pause interval of more than 1.5 characters before the completion of
the message frame transmission, the receiving device will refresh the incomplete
message and assume that the next byte is the beginning of a new message. Similarly, if
a new message starts after the previous frame in less than 3.5 characters, the receiving
device will consider it a continuation of the previous frame, and this will cause an error
because of the final CRC The value cannot be correct.
The meter uses the function code 0x04 to complete the output of the measurement
results and the output of two current values.The meter uses the function code 0x04 to
complete the output of the measurement result and the output of the two current values.
