5 Device Description
1) Battery compartment cap
2) Main display
3) Power button
4) Electrode collar
5) Electrode module
6) Electrode
7) Protective cap
6 Operating Instructions
6.1 Preparation
1. Remove the protective cap from the meter to rinse the electrode with clean
water and then wipe it dry. Do not touch or wipe the surface of the inner
black sensor of the electrode.
2. Open the battery compartment to take out the screwdriver.
3. Press the button to turn the meter power on.
6.2 Calibration
1. Dip the electrode into the calibration solution. Stir gently and wait until the
display is stabilized. Adjust the reading to 94 (940 ppm) at 25 ℃by turning the
trimmer (Span) located at left side of battery compartment with the calibration
screwdriver.
2. Calibration is complete.
3. There is no need to calibrate before each usage. Calibration should be performed
every two weeks or after 10 times of usage.

6.3 Measuring with the Conductivity Meter
1. After calibration, rinse the electrode with clean water and wipe it dry. Do not
touch or wipe the surface of the inner black sensor of the
electrode. Dip the electrode into the sample solution to be measured. Stir gently
and wait until a stable reading can be obtained.
2. Read the measurement on the display. The reading should be multiplied by a
factor of 10 to obtain the true conductivity value.
3. After measurement, rinse the electrode with clean water and replace the protective
cap. Do not touch or wipe the surface of the inner black sensor of
the electrode.
6.4 Changing the battery
1. The installed Lithium CR2032 batteries have a typical life span of 100 hours.
Replace the battery when the display begins to fade or flash.
2. Loosen the battery compartment cap.
3. Replace the old batteries with fresh Lithium CR2032 batteries, noting the polarity.
4. Replace the battery compartment cap tightly.
5. Recalibrate the meter after changing the batteries.
6.5 Electrode Replacement
1. As long as the electrode can be calibrated and remains responsive it is still useful.
When either of these begin to fail, you will need to replace the electrode. (This is
not covered under the warranty).
2. Unscrew the electrode collar and remove it completely.
3. Pull the electrode module out from the tester.
4. Plug in a new electrode module into the tester socket carefully.
5. Replace and tighten the electrode collar to make a good seal.
6. Make sure to calibrate the new electrode before usage.
