Operating Instructions
Function selection
1) Turn on the meter by pressing the Power Button. To turn the meter
off, hold the Power Button for over 2 seconds.
2) The meter has 3 measuring functions to choose from:
Conductivity, TDS, and Salt.
When the meter is on, press and hold the Function Button. The display
will ash “Cd”, for Conductivity measurements, “tdS” for TDS measure-
ments, and “SALt” for Salt measurements. Release the Function Button to
choose the displayed function. The meter’s defaults are following:
Display Unit: Conductivity
Temperature Unit: °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
The meter is defaulted to Auto Range mode. Push the Range Button to
change the range from 200µS, 2mS, 20mS, 200mS and Auto Range.

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 sec-
onds 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
1) Prepare the optional standard conductivity solution
2) Install the Probe Plug into the Probe Socket
3) Power on the meter by pressing Power Button
4) Hold the Probe Handle and let the Sensing head get fully immersed
the calibration solution. Shake the probe to let the probe’s internal
air bubble drift out from the sensing head. The display will show the
conductivity values.

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 ad-
just the upper display value to be the exact same as the standard
conductivity value. Press the Enter Button to save the calibration
data and nish 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 proce-
dures should execute the 2mS range (1.413mS Cal.) calibration at
rst, 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 maxi-
mum value, press the Hold Button once and the display will show
a “REC.” symbol only and execute the memory function continu-
ously.
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.

Backlight ON/OFF
After powering the meter ON, the LCD Backlight will turn on automati-
cally. 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 rst time, it is
recommend to format the SD card. See Advanced Settings section
of this manual for instructions.
3) If this is the rst time the meter is used you need to adjust the
clock. See Advanced Settings section of this manual for instruc-
tions.
4) Now you need to set the decimal format. The numerical data struc-
ture 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 ash while the measuring data and time informa-
tion 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 But-
ton once. While paused, the “REC” symbol will stop ashing. Press
the Logger Button again to resume Datalogging, and the “REC”
symbol will begin to ash again.

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 ash once and one Beep will
sound, at the same time the measuring data along the time infor-
mation 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 ash 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
conrm.
3) Stop Datalogging; press the REC Button for 2 seconds, and the
“REC” symbol will disappear indicating the Datalogging function
has stopped.
Checking the Time
During normal functions (not Datalogging), press the Time Check Button
and the lower LCD display will show the Year, Month/Date, Hour/Minute.
Check Sampling Time Information
During normal functions (not Datalogging), press the Sampling Button and

SD Card Data Structure
1) The rst time the SD card is used in the meter, the SD card will
generate a folder: CDA01
2) The rst time you use the Datalogger, in the folder CDA01, a new
le name CDA01001.XLS will be created. The Datalogger will use
this le until the Data has reached to 30,000 rows. The meter will
then will generate a new le with a subsequent number, for ex-
ample CDA01002.XLS.
3) The folder CDA01 can hold 99.XLS les. 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 les from the SD
Card to the computer by opening up the SD folder and selecting
the desired EXCEL les, and drag-and-drop them onto your Com-
puter. Open the les with EXCEL (File – Open).
4) The EXCEL le will have the following column headers in this order:
Place (Position Number), Date (Year/Month/Day), Time (in 24h
clock), Value & Unit.
