pH (& ORP) WIRING DIAGRAM
6. WIRING
6-1. Conventional pH (& ORP) Wiring
Connect the PH20 or FU20 to the EXA or
EXAxt PH Analyzer as shown (Fig 12). With
this configuration, it is possible to measure
ORP (or rH) at the same time (Refer to the
EXA or EXAxt Manual for appropriate impe-
dance jumper and Service Code settings).
6-2. Wiring for ORP measurement with
normal reference
Connect the PH20 or FU20 to the EXA or
EXAxt PH Analyzer as shown (Fig 13).
Refer to the EXA or EXAxt Manual for
appropriate impedance jumper and Service
Code settings).
6-3. Wiring for ORP measurement with
pH reference
Connect the PH20 or FU20 to the EXA or
EXAxt PH Analyzer as shown (Fig 14).
Refer to the EXA or EXAxt Manual for
appropriate impedance jumper and Service
Code settings).
