2.3 Electrode mounting 2.3.1 Electrode shape and installation form KS-1 Conduvtivity sensor... - Page 7 2.3.2 Common installation methods Installation of sensors is a very careful work, please install sensors must carefully select the installation site, deliberate installation methods, so as to avoid the measurement data distortion. The electrode joint in figure A is too long, and the extension part is too short. The dead cavity is easy to be formed in the sensor, resulting in measurement error.
- Page 8 Other common wrong installation methods: The measurement error or instability can be caused by the flow cannot guarantee the full pipe or high gas accumulation. 2.3.3 Installation precautions and maintenance The flow cell should be installed in the pipeline where the flow rate is stable and it is not easy to produce bubbles.
- Page 9 Please keep the electrode measurement part clean when installed. Don't touch the surface directly with hands or dirty objects. After contact with greasy dirt, grease and glue, the accurate value can’t be measured for a longtime. The conductivity cell is a precise measuring component. It can’t be decomposed and change the shape and size of the electrode.

Page 15: Ⅴ Menu Introduction
Ⅴ Menu introduction According to the different functions, the controller is divided into four first-level menus, each first-level menu includes two-level or even multiple secondary menus, each menu has a number, which is easy to view and set the instrument parameters. And the secondary menu will display the setting parameters of the controller in the upper right of the screen according to the function, and the user can know the instrument parameters without entering the subordinate menu. - Page 16 Language 1. English 2. 简体中文 5.1 System Settings Menu 1.1 Language This instrument supports Chinese and English two languages, two languages can switch freely. For example: select simplified Chinese and press Enter key to confirm, the whole display interface of the instrument will be changed into simplified Chinese. Note：In order to prevent the user from misoperation, after the customer selects the parameter and presses the "Enter", there will be four prompts “ESC”, “OK”, “NO”...

- Page 18 Menu 2.3 Digital filtering Digital Filter The measured value of the meter is filtered by means of averaging, and three digital filtering methods are supported. 2.3.1 L Low point: average every 5s. 2.3.2 M Midpoint: average every 10s. 2.3.3 H High point: average every 20s.
- Page 19 parameter according to the actual situation. After pressing the Enter key to confirm, the measured value will change according to the temperature compensation parameter. Note:The temperature compensation reference temperature of the instrument is fixed at 25 °C, and the calculation formula is: Ct = C25{1+α(T-25)} C25 is COND/Resistance value at 25 °...
- Page 20 The user can freely set the hysteresis value within the range allowed by the meter and press Enter to confirm. Note: Greater than (or less than) the alarm trigger value is pulled in. Below (or greater than) the hysteresis value is released. The relay action diagram is as follows: An example of the high point mode is: High point Relay 1 mode = high point.
