hold for 3 sec. to enter calibration mode. The
display will appear CAL and flashing 1413µS/cm.
When the display stops flashing and indicates “SA",
then "End” while calibration ends, and will return to
measurement mode.
Note:
1. Calibrated by 12.88 mS/cm standard solution would
be better for measuring high conductivity solution.
2. The icon COND will display automatically during
calibration mode.
3. Calibration error indicator icon will appear, and “Err”
instead of “SA”, if calibration fails.
4. If the reading is not 0 µS/cm while the cell is in the air
and not dipped into any solution, calibrate it in the air
to make reading becomes 0 µS/cm.
5. The calibration point of Conductivity are 0, 84 µS/cm,
1413 µS/cm, 12.88 mS/cm and 80.0 mS/cm.
<DO>
1. Make sure the sensor is DO probe and remove the
protection cap.
2. Press to turn on power and press to
choose O

mode. Wait 10 minutes to 30 minutes for
the probe to polarize. The reading should be approx.
101.7% (saturation) after the probe has completely
polarized
3. Let the probe in the air. Press and hold
