Appendix “Temp. Compensation” - Temperature compensation

pH measurements are temperature dependent. The degree to which temperature affects mV readings varies from solution 
to solution and can be calculated using the following graphic.

Instrument has either fixed or adjustable automatic temperature compensation referenced to a standard temperature of 
25°C.  

To end procedure move cursor on “OK” and press wheel to proceed to “Save” request screen. Move wheel on “YES” to 
save or “NO” to discard changes.
