2 Elite CTS Tester Operating Instructions
This instruction manual is applicable for Elite CTS Tester.
Replacing the Batteries
The Elite CTS tester uses four AAA 1.5 V batteries.
1. To remove the battery cover, See Figure 1. Clear the front catch and then the back
catch, before sliding the cover off.
2. To remove the battery plate, push the center tab towards the front of the tester as
show in Figure 2. Once unlocked, remove the plate to access the batteries.
3. Invert the tester upside down to remove the batteries. Each side uses two
AAA batteries. Orient each battery with positive terminal facing downward.
4. To lock the battery plate, align the small taps into the guide ribs
on the housing and then press down. See Figure 4.
Getting Started
The Elite CTS tester has been factory calibrated and usually works well out of the box. However, after extended
periods of non-use, it is best to remove the sensor cap and soak the sensor in warm tap water for 10 minutes or so.
Prior to taking the measurements, periodic callibaration with certied standards is recommended for best accuracy.

Calibration for Conductivity, TDS, or Salinity
For best results, periodic calibration with an accurate standard is recommended prior to measurement. Use the
calibration standard value that is close to your intended sample value.The tester will retain one calibration value in
each mode (conductivity, TDS, salinity) when the instrument is powered off. The conductivity value can be calibrated
automatically or manually, while the TDS & salinity values require manual calibration. The tester will begin in the
measurement mode that was used when it was powered off. See “Elite CTS Measurement Parameter Setting” to
change the desired parameter.
Automatic Calibration for Conductivity
1. Remove the cap and press the to power on.
2. Dip the sensor in at least 30 mm of calibration standard.
3. Stir gently and press to begin the calibration.
4. The display will show CAL followed by the default value. CAL is indicated on the display during calibration mode.
5. If the reading is within the calibration range of the automatically recognized standards; 80 (84 µS/cm),
1410 (1413 µS/cm), or 12.90 (12.88 mS/cm), the icon is displayed when the automatic calibration standard
value has been detected.
6. Press to accept the auto conductivity standard and nish the calibration.
7. Display returns to Measurement window.

Manual Calibration
When the conductivity reading is outside calibration range of the automatic conductivity standards or when TDS or
salinity is used, the tester will require manual adjustment.
1. Repeat steps 1 to 4 from “Automatic Calibration for Conductivity”.
2. Press to manually adjust the value to the desired reading.
Note: The adjustment will decrease only, however the adjustment will eventually cycle to the highest available value
after decreasing by 40% of the initial value.
3. Press to accept and nish the calibration when the desired value is selected.
4. To abort calibration, press to escape.
5. Once the calibration is nished and user has accepted the changes, measurement window will now show the
calibrated reading.
Note: The auto conductivity standards are 84 µS/cm, 1413 µS/cm & 12.88 mS/cm.
CTS Measurement
1. Press to power the tester on if needed.
2. Dip the electrode about 2 cm to 3 cm into the test solution. Stir and let the reading stabilize. The timer icon will
blink during this time. Once the reading is stabilized, the timer stops blinking and will appear to indicate the
stability of the reading.
CAUTION: Testing dry samples is not accurate and can lead to sensor damage or
breakage. Soils must be wet and free of particulates that may scratch the
glass sensor. Excessive force into dry samples can cause glass breakage.
3. Note the CTS value or press to freeze the reading. To release the reading, press again.
4. Press to turn off tester. If key is not pressed for 8.5 minutes, the tester will automatically shut off to conserve
batteries.
User Reset
Reset the CTS calibration to the user’s default settings by using the user reset function. Temperature user calibration
is not affected by the user reset function.
1. Press to enter setup window. Scroll down by pressing to select Reset. Press to select Reset. The
display shows User Reset and Fact Reset.
2. Press to select User Reset.

Sensor Maintenance
1. Always keep the sensors electrodes clean. Rinse the electrodes with de-ionized water and wipe them dry with
clean cloth before storing with its protective cap. For cup type electrodes, remove the white plastic cup and insert
to thoroughly clean viscous solutions. Never scratch electrodes with a hard substance.
2. For better performance, soak the electrode in alcohol for 10 to 15 minutes and rinse with de-ionized water before
starting any measurement process. This is to remove dirt and oil stains on the electrode which may affect the
accuracy of the measurements.

Return of Items
Authorization must be obtained from your distributor before returning items for any reason. When applying for
authorization, please include information regarding the reason the item(s) are to be returned.
We reserve the right to make improvements in design, construction and appearance of products without notice.
Prices are subject to change without notice.
Sensor Replacement
Replace the sensor module at the fraction of the cost of a new tester. When the tester fails to calibrate or gives
uctuating readings in calibration standards, you need to change the electrode.
1. With dry hands, grip the ring with sensor facing you. Twist the ring clockwise. Save the ring for later use.
2. Pull the old sensor module away from the tester.
3. Align the four tabs on the new module so that they match the four slots on the tester.
4. Gently push the module onto the slots to sit it in position. Push the smaller O-ring fully onto the new sensor
module. Push the other O-ring over the module and thread it into place by rmly twisting counter clockwise.
Note: It is necessary that you recalibrate your tester prior to measurement after a sensor replacement.
Self Diagnostic Messages
Batteries are weak and need replacement soon.
stable error Appears when calibration is attempted but the reading is not yet stable. Wait for the
reading to stabilize or manually conrm the calibration by pressing enter.
