Getting Started
Thank you for entrusting Jenco for your water quality
measurements. Please follow the steps below to start using
your conductivity or TDS tester.

Understand the 3 operation modes
【 Measure Mode】
Measure Mode is used to make all conductivity, TDS and temperature
measurements.
【 Calibration Mode】
Calibration Mode is used to perform 1 point conductivity calibration.
【 Hold Mode】
Hold Mode is used to hold and lock the display at the most recent
measurement values. Once in Hold Mode, the tester can be removed
from the measuring solution without affecting the displayed
measurement values.

Calibrate
1. Remove the electrode cap of the instrument and rinse the
electrode & ATC assembly in distilled water.
2. Immerse electrode assembly into the standard solution.
Use the following table to determine the right standard
solutions for your tester.
3. Note the temperature displayed is the temperature of the
standard solution.
4. Press the “Cal” button for 2 seconds to enter the calibration
mode. Conductivity or TDS value of the standard solution
and “Cal” indicator is displayed.
5. Calibration data will automatically be stored when the
measurement values are stable.
6. Calibration is complete.
8
Measure
1. From “Measure Mode”, dip the electrode end of the tester
into the test solution.
9
Hold Data
1. When the conductivity or TDS reading is stable, press “Hold”
key once to hold and lock the display to the latest
measurement values.
2. Press “Hold” key again to release and unlock the display and
the tester returns to “Measure Mode”. The unit is now ready
for another measurement.
