°C
Temp. Compensation Factor: 2.0% per °C
Auto range: ON
Auto power off: ON
Datalogger Sampling Time: 2 seconds
Conductivity Measurement
1) When the meter is off, plug the Probe Plug into the Probe Socket, then power on the meter by pressing the Power Button.
2) Select the “Cd” function (see Function Select).
3) Hold the Probe Handle and fully immerse the Probe Sensor into the measuring solution. Shake the Probe to let the Probe’s internal air bubble drift out from under the sensing head. The top part of the
Display will show the conductivity mS (µS) values, and the lower part of the Display will show the temperature value of the solution.
Manual Range

Only if you REALLY need them:
Zero Adjustment
If the probe is not immersed in the measuring solution and the display will not show a Zero Value. Press and hold the Up Button for about 10 seconds and the display will then show zero. The Zero function is only valid for the 200µS range and not when the Zero Value is < 2.0µS.
TDS Measurement
1) When the meter is off, plug the Probe Plug into the Probe Socket, then power on the meter by pressing the Power Button.
2) Select the “tdS” function (see Function Select)
3) Hold the Probe Handle and fully immerse the Probe Sensor into the measuring solution. Shake the Probe to let the Probe’s internal air bubble drift out from under the sensing head. The Display will show the Total Dissolved Solids value.
Salt Measurement
1) When the meter is off, plug the Probe Plug into the Probe Socket, then power on the meter by pressing the Power Button.
2) Select the “SALt” function (see Function Select)
3) Hold the Probe Handle and fully immerse the Probe Sensor into the measuring solution. Shake the Probe to let the Probe’s internal air bubble drift out from under the sensing head. The Display will show the Salt value (% of weight).
Calibration

5) Press the REC Button and HOLD Button at the same time. The display will show the symbol “Cd” and “CAL”
6) Press the Enter Button and the measuring value will show on both the upper and lower Display. Use the Up and Down Buttons to adjust the upper display value to be the exact same as the standard conductivity value. Press the Enter Button to save the calibration data and finish the calibration procedures.
NOTE: If you only intend to make a one point calibration, executing the
2mS range (1.413mS Cal.) is enough. Multi-point calibration procedures should execute the 2mS range (1.413mS Cal.) calibration at first, then make other ranges (20µS range, 20mS range or 200mS range) after if necessary.
Data Record (Max., Min. reading)
The data record function records the maximum and minimum readings.
Press the REC Button once to start the Data Record function and a “REC” symbol will appear on the display. With the “REC” symbol on the display:
1) Press the REC Button once, and a ”REC. MAX.” symbol along with the maximum value will appear on the display. To delete the maximum value, press the Hold Button once and the display will show a “REC.” symbol only and execute the memory function continuously.
2) Press the REC Button again, and a “REC. MIN.” symbol along with the minimum value will appear on the display. To delete the minimum value, press the Hold Button once, and the display will show a “REC.” symbol only and execute the memory function continuously.
3) To exit the memory record function, press the REC button for 2 seconds. The display will revert to the current reading.

After powering the meter ON, the LCD Backlight will turn on automatically. While taking measurements, press the Backlight Button and the LCD
Backlight will turn off. Press the Backlight Button once again to turn the
LCD Backlight back ON.
Datalogger
Preparation Before Executing the Datalogger Function:
1) Insert the optional SD card into the SD card socket.
2) Before you use an SD card with this meter for the first time, it is recommend to format the SD card. See Advanced Settings section of this manual for instructions.
3) If this is the first time the meter is used you need to adjust the clock. See Advanced Settings section of this manual for instructions.
4) Now you need to set the decimal format. The numerical data structure downloaded to the SD card is defaulted used the “.” as the decimal, for example “20.6” “1000.53”. But in certain countries the
“,” is used as the decimal point, for example “20,6” “1000,53”. See
Advanced Settings section of this manual for instructions on how to change the Decimal Character.
Auto Datalogger (Set sampling time ≥1 second)
1) Start Datalogging; press the REC Button, and the “REC” symbol will appear on the LCD screen, then press the Logger Button, the
“REC” symbol will flash while the measuring data and time information is being saved in memory. To set the sampling time, and to toggle the beeper sound on or off, refer to the Advanced Settings section of this manual.
2) Pause the Datalogging; while Datalogging, if press the Logger Button once. While paused, the “REC” symbol will stop flashing. Press
Pantone 123 Yellow
Blue - 100/80/30/5
Yellow - 0/27/100/0

Only if you REALLY need them:
3) Stop Datalogging; while the Datalogger function is paused, press the REC Button for 2 seconds. The “REC” symbol will disappear indicating the Datalogging function has stopped.
Manual Datalogger (Set sampling time = 0 seconds)
1) Set sampling time is to 0 second; Press the REC Button, and the
“REC” symbol will appear on the LCD screen. Press the Logger
Button, and the “REC” symbol will flash once and one Beep will sound, at the same time the measuring data along the time information will be saved in memory. The lower Display will show the
Position (record) number, which is saved as well.
2) To Change the Position Number; press the Down Button and the lower position number will flash on the display. Press the Up or
Down Buttons to set the Position Number (1 to 99) to help identify the measurement location. The lower Display will show P x (x = 1 to
99). After the position number is selected, press the Enter Button to confirm.
3) Stop Datalogging; press the REC Button for 2 seconds, and the
“REC” symbol will disappear indicating the Datalogging function has stopped.

Only if you REALLY need them:
SD Card Data Structure
1) The first time the SD card is used in the meter, the SD card will generate a folder: CDA01
2) The first time you use the Datalogger, in the folder CDA01, a new file name CDA01001.XLS will be created. The Datalogger will use this file until the Data has reached to 30,000 rows. The meter will then will generate a new file with a subsequent number, for example CDA01002.XLS.
3) The folder CDA01 can hold 99.XLS files. When that number has been reached, the meter will then will generate a new folder with a subsequent number, for example CDA02. Max number of CDA-- folders is 10.
Data Transfer from SD card to Computer (EXCEL Software)
1) After Datalogging, remove the SD card from the SD card slot.
2) Plug in the SD card into the Computer’s SD card slot or insert the
SD card into the optional SD card adapter and connect to your
Computer. Turn your computer on and a folder will appear on your desktop representing you SD card.
3) Open “Microsoft EXCEL”. Download the EXCEL files from the SD
Card to the computer by opening up the SD folder and selecting the desired EXCEL files, and drag-and-drop them onto your Computer. Open the files with EXCEL (File – Open).
4) The EXCEL file will have the following column headers in this order:
Place (Position Number), Date (Year/Month/Day), Time (in 24h clock), Value & Unit.
