To obtain the highest accuracy for measurements it is important to follow these tips:
• Calibration is only as good as the solution being used. The calibration solution
values change over time. Fresh solution should be used for each calibration.
• The probe should be rinsed with purified water each time before placing in
calibration solution or sample to be tested.
Care and Maintenance
Error messages
During user calibration, if the reading is out of the accepted range, the meter will
display “---- Err“.i.e. 10.00 ppt blinking means the limit of the measured value is
out of range.
If the measured temperature is higher than 50.0 ºC or lower than 0.0 ºC, the 50.0 ºC or
0.0 ºC temperature value will blink on the LCD in measure mode.
2. Place the probe in calibration solution. The probe tip should be centered in the
solution and submersed 1.18” (3 cm). The meter 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 meter returns to
measurement mode.
Calibration Procedure
Measurement and Calibration
For better accuracy, frequent calibration of the meter is recommended. 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 meter ON. Place the probe to the desired 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 meter has been calibrated.
• Press CAL button to enter calibration mode from measurement mode.
• The meter will enter the calibration mode, displaying “ppt 6.44 USE” with CAL
tag blinking.
1. Pour 2” (5 cm) of standard solution into a container.
Clear Calibration
Place meter in calibration mode. Press ON/OFF and “Clr” is displayed. The meter will
now be at default calibration.

Battery Replacement
To change the CR2032 Li-ion battery, turn the battery cover located on the back of
the meter counterclockwise to unlock. Remove cover and replace with new battery
+ side facing up.
Note: Batteries should only be replaced in a safe area using the battery
type specified in this instruction manual. Old batteries should be disposed in
accordance with local regulations.
The meter 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 meter will turn off.
