the screen will display
, indicating the electrode needs cleaning.
4.1.2 Set calibration standard solution
The six predefined standard solutions are 10 μS/cm, 84 μS/cm, 146.5 μS/cm, 500
μS/cm, 1413 μS/cm and 12.88 mS/cm.
To set the standard solution:
1. Touch the
Menu
icon
to enter menu option.
2. Touch
Setup
, and then touch
Conductivity
.
3. Touch
Std.Solution

2. Touch
Setup
, and then touch
Conductivity
.
3. Touch
