Preface
Please read this manual carefully before use.
When receiving the instrument, please open the package carefully, check whether the instrument and accessories are damaged by trans-
portation 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,
1. Apparent damage to the analyzer
2. The analyzer does not work properly or provides specied measurements
3. The analyzer has been stored for a long time in an environment where the temperature exceeds 70°C
The analyzer must be installed by licensed professionals in accordance with relevant local specications, and instructions are included in
the operation manual. Comply with the technical specications and input requirements of the controller.
Features
The instrument is equipped with different types of pH or ORP sensors. Widely used in power plants, petrochemical industry, metallurgical
electronics, mining, paper industry, biological fermentation engineering, medicine, food and beverage, environmental protection water
treatment, aquaculture, modern agricultural planting and other industries. The pH (acidity and alkalinity) value, ORP (redox potential) value
and temperature value of water solution were continuously monitored and controlled.

Calibration of Standard Solution
The sensor has been factory calibrated before delivery and users can use it directly.
Note: Calibration if required can be made using at least one of the ve calibration points. Not all points are
required for sensor calibration
If calibration is required, prepare a suitable standard reference liquid with known range value. Press the [MENU] button to enter the
Setting Mode — select the calibration point.
Enter the corresponding reference calibration value, then press [ENT] key to conrm and enter the calibration screen.
(If the instrument has been calibrated, the screen shows the calibration status. press the key to switch the calibration state of the
calibration point. If re-calibration is required in this mode, press the [ENT] key again to enter the re-calibration.)
In the standard solution calibration mode, press the key to switch the calibration points, press the [ENT] key to start calibrating.
If prompted to enter the calibration security password, press the key or key to set the calibration security password, and
then press the [ENT] key to conrm the calibration security password.

Calibration point 1: After entering the calibration mode, the current measurement value will be displayed. This is known as the standard
solution value.
Place the electrode into the standard solution of the corresponding value, and the corresponding voltage mV value and calibration state
will be displayed on the screen.
After completion of calibration, Done will be displayed on the right side of the screen.
If you want to calibrate the next point, press the key to switch the calibration point.
If only one point calibration is required, press the [MENU] key to return to the superior menu after calibration.
During the calibration process, the calibration status will be displayed on the right side of the screen. Done indicates successful calibration,
Calibrating indicates in calibration, and Error indicates a sensor or a calibration issue.
Field Calibration — Select on-site calibration methods: [Linear calibration] , [Offset adjustment] , [linear adjustment].
