OPERATION 

 
 
This mode is used to measure oxidation/ reduction potential 
(ORP/redox), perform titration and to verify the function of the meter. 
The mV measure function allows you to continuously monitor the mV 
potential of the electrodes in use. This can be done in either absolute 
or relative mV. 
 
In the millivolts mode, the current millivolts output from the electrodes 
being used is monitored and displayed on the screen. The meter will 
continually monitor the millivolts reading in this mode and will not lack 
onto a single reading. However, once the reading has become stable, 
a stable message will be displayed. Remember to setup your mV 
measuring mode parameters. Refer to pages 73-78 for mV setup 
instructions.
