NOTES:
1. For pure water samples in non-conductive (plastic, glass, etc.) piping, ground the black cell electrode lead near the cell. Alternatively,
connect to the 7082 ground screw as shown dotted. Do not ground 10, 25, or 50 constant cells.
2. 7
0 8 2- 1 6, 17 , 1 8 , 1 9 (only)
Use 22 gage minimum coaxial cable type RG59/U connecting shield to terminal "SH" only.
3. 7
0 8 2 -1 6 , 1 7 , 1 8 , 1 9
For cable runs of up to 500 ft., use: 18 gage minimum, three conductor cable.
For cbale runs of 500 - 1000 ft., use: 16 gage minimum, three conductor cable.

08 2 -1 3 , 14 , 1 5 [coax and shield (SH) not used]
For cable runs of up to 500 ft., use: 18 gage minimum, four conductor cable.
For cable runs of 500 - 1000 ft., use: 16 gage minimum, four conductor cable.
