 Immersion Method
NOTE: Use this method for pools, spas and other large standing bodies 
of water.
1.  Hold instrument beneath the surface of the water to avoid 
surface effects on the water’s chemistry.
2.  Swirl the instrument around for at least 10 seconds to thoroughly 
rinse the cell cup and sensor well.
3.  Continue holding the instrument under the surface while taking 
the reading.
4.  Press  .
5.  The instrument will begin alternating between a predicted nal 
ORP value and a free chlorine equivalent concentration in ppm.  
Both readings will change rapidly at rst.
6.  Wait for the readings to stabilize. When the mV and ppm values 
are  unchanging  for  5  consecutive  readings,  the  FC

  reading 
has  reached  a  stable  level.  This  may  take  1  to    2  minutes. 
NOTE: If the reading takes longer than 1 minute to stabilize,
press   after 1 minute to prevent Auto-OFF feature from
disturbing  the measurement  process.  Annunciators will  alert 
you when either the pH or ORP of the nal FC
