(4) Cell constant setting (C.C) panel
This panel with the mark is used to set the cell constant manually.
Use the keys to set the cell constant. Then press the F/ENT key.
Typical cell constants are as follows:
For pure water sensor (SC72-11): 0.05 cm -1
For general-purpose (SC72-21, -23) and chemical-resistant sensors (SC72-31): 5 cm -1
Sensors for high-conductivity measurement: 50 cm -1
When setting the cell constant, you should check the nameplate (attached to sensor cable)
for the model number and cell constant.
The cell constant can be set in the range
؎ 20% of standard cell constant. For example,
for general-purpose sensors with standard cell constant of 5 cm -1 , a cell constant ranging
from 4.00 to 6.00 can be set.
Once the cell constant is set, it remains stored in memory even when batteries are
removed.
The general-purpose cell has the same cell constant whether used with SC72-21 or SC72-
23 type.
Refer to Sec. 2.4 for cell constant setting procedure.
