Elite CTS Tester Operating Instructions
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 finish the calibration when the desired value is selected.
4. To abort calibration, press
to escape.
5.
Once the calibration is finished 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.
