INSTRUCTION MANUAL
Measurement & Calibration
Calibrate the electrode before using. For best results it is
recommended to recalibrate periodically.
In addition, the instrument must be recalibrated:
• When high accuracy is required.
• At least once a month.
Measurement
Press the ON/OFF button to turn the tester on. Place the probe in
solution. The conductivity value, automatically compensated for
temperature, will be shown on the LCD.
The measured temperature will be shown on the secondary LCD.
Note:
Before taking any measurement make sure the tester
has been calibrated.
Calibration Procedure
• Press CAL button to enter calibration mode from measurement
mode.
• The tester will enter the calibration mode, displaying “mS/cm
12.88 USE” with CAL tag blinking.
1. Pour 2” (5 cm) of standard solution into a container.
2. Place the probe in calibration solution. The probe tip should be
centered in the solution and submersed 1.18” (3 cm). The tester
will automatically recognize the solution.
3. If the solution is not recognized or is out of the accepted range
“---- Err“ is displayed.
4. If the calibration solution is recognized “REC“ is displayed until
the reading is stable and the calibration is accepted.
• After acceptance, the “Stor“ message is displayed and tester
returns to measurement mode.
Clear Calibration
Place the tester in calibration mode. Press ON/OFF and “Clr” is
displayed. The tester will now be at default calibration.
Error Messages
“---Err” displayed during calibration indicates that the solution is
not recognized or out of accepted range.
20.00 mS/cm displayed blinking during measurement indicates
that the reading is out of meter range limits.
50.0 °C or 0.0 °C displayed blinking during measurement indicates
that measured temperature is out of accepted range.
Care & Maintenance
Please read the information below, to ensure the highest possible
accuracy:
• Fresh buffer should be used for each calibration, once the sachets
are opened the buffer value can change over time.
• If measurements are taken successively, rinse the probe
thoroughly in distilled or deionized water to eliminate cross-
contamination.
Battery Replacement
The tester features a low battery indicator. When the battery is
running low (under 10%), the battery indicator will blink on the
LCD. When the battery is discharged “
dEAd bAtt
” will be displayed
on the LCD for 2 seconds and the tester will turn off.
To change the CR2032 Li-ion battery, turn the battery cover located
on the back of the tester counterclockwise to unlock. Remove cover
and replace with new b side facing up.
