*IMPORTANT – PLEASE READ BEFORE YOU CONTINUE*

PLEASE USE THIS MANUAL IN THIS ORDER :

Step 1:

Use the first half of this manual “General Guide” and “Temperature” to set up and
calibrate your instrument (Pages 1 - 39).

Step 2:

Then go to the specific parameter guides (eg. pH, Conductivity, TDS etc) which are
relevant to the model you have purchased. (Pg 41 onwards).

CAUTION:

Do not skip the general guide as your meter will not be configured to read

accurately if your set-up and calibrations are not done accordingly.

Thank you for reading this page. Please proceed.
