Conductivity
.
3. Press the
button to turn to the next page and then touch
Temp.Coeff.
.
4. Press the
or
button to adjust the value. Touch the value on the screen to
confirm your setting.
Note
:
If you set the temperature correction coefficient value as 0.0 %/°C, there will be no
temperature compensation for the conductivity measurement. The meter will display the
real conductivity value at current temperature without compensation.
4.1.5 Set TDS factor
To set the TDS factor:
1. Touch the
Menu
icon
to enter menu option.
2. Touch
Setup
, and then touch
Conductivity

button to adjust the value. Touch the value on the screen to
confirm your setting.
4.2 Conductivity calibration
Set the calibration standard solution and cell K value before performing the calibration.
Please refer to the above
Set calibration standard solution
and
Set cell K value
section for details.
To start calibration:
1
Touch the mode area one or several times to select
EC
.
2
Touch the
icon on the screen.
3
Touch
COND
if you are using an a-AB33M1 model. Skip this step if you are using
other models.
4
Follow the instruction on the screen to rinse the electrode, place it in a standard
solution, stir 5 seconds, and wait for 30 seconds.
5
Press the
button when you finish the previous step to start calibration. The
icon on the screen starts to blink during the process.
Note
:
Calibration
starts with the Auto End Point Mode.
Pressing the
button during the calibration can cancel the process.
6
The meter reaches endpoint automatically. The screen will display the calibration
point EC value (e.g. 12.88) with the temperature.
a) Touch
Finish
to complete the calibration, and the calibration result will be
shown.
