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
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.
Error messages
During user calibration, if the reading is out of the accepted range, the meter will
display “---- Err“.i.e. 3000 ppm 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 buffer 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
EC 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 “mS/cm 1.41 USE” with
CAL tag blinking.
1. Pour 2” (5 cm) of standard solution into a container.
• After entering in the calibration mode and before the point is accepted, it is
possible to quit the procedure and return to the last calibration data by pressing
the CAL button. The LCD displays ”----ESC” for 1 second and the meter returns to
measurement mode.
Quick Calibration
Select calibration type “CAL quic “ from meter setup.
• Enter calibration mode.
• Immerse the probe in the HI50036 calibration solution.
• When the standard values is recognized and stability is reached the meter
automatically accepts the calibration.
• The LCD will display “Stor“ for 1 second and return to normal measurement mode.
• If the standard is not recognized or the slope is out of accepted range “----Err‘ is
displayed. Change the calibration solution, clean the electrode or press any key
to exit calibration.
• When the calibration procedure is completed, the “CAL“ tag is turned on.
Clear Calibration
Place meter in calibration mode. Press ON/OFF and “CLR” is displayed. The meter
will now be at default calibration.

Preliminary Examination
Remove the meter from the packing material and examine it carefully to make sure that
no damage has occurred during shipment. If noticeable damage is evident, contact your
local Hanna Instruments Office.
Each meter is supplied with:
• CR2032 battery (1 pc.)
• Storage / Protection sleeve
• Instruction manual
• Quality Certificate
Note: Save all packing material until you are sure that the instrument functions
correctly. All defective items must be returned in the original packaging with the
supplied accessories.
Preparation
The probe is shipped dry. Before using the electrode, remove the protective cap. Then
follow the calibration procedure.
• Turn the tester on by pressing ON/OFF button.
• Remove the protective cap and immerse the tip of the probe in the sample to
be tested.
• Stir gently and wait for a stability tag to disappear.
• The electrode automatically compensates for temperature variations.
• The reading on display is directly expressed in: mS/cm or ppm.
• For best results, recalibrate periodically.
• After use rinse the probe with water.
• Always replace the protective cap after each use.
