6.6.1 Selecting measurement range and cell constant
Use this parameter to select the measurement range (and appropriate cell constant)
in which you want to operate your controller. A single digit number corresponding to
the range and cell constant you select will appear in the lower left hand corner of the
display during measurement mode.
If you have a conductivity controller:
This parameter lets you select from
seven conductivity ranges and four
cell constants (K) in ten possible
combinations:
1. 0.000 to 2.000 µS, K = 0.01
2. 0.00 to 20.00 µS, K = 0.01
3. 0.00 to 20.00 µS, K = 0.10
4. 0.0 to 200.0 µS, K = 0.10
5. 0.0 to 200.0 µS, K = 1.00
6. 0 to 2000 µS, K = 1.00
7. 0 to 5000 µS, K = 1.00
8. 0.00 to 20.00 mS, K = 1.00
9. 0.0 to 200.0 mS, K = 10.0
0. 0.0 to 200.0 mS, K = 1.00
If you have a resistivity controller:
This parameter lets you select from two
resistivity ranges and two cell constants
(K) in two possible combinations:
1. 0.00 to 20.00 m
Ω
, K = 0.01
2. 0.00 to 2.000 m
Ω
, K = 0.10
From measurement mode:
1.
Enter Advanced set-up mode.
Push the ENTER key. Press the
▲
key to scroll to security code
“22”. Push the ENTER key again.
2.
Press the
▲
and
▼
keys
to scroll
until the upper display shows rng.
3.
Press the ENTER key
until the
upper display shows the top value
of a range and the lower display
shows the cell constant.
See bold figure at right
4.
Press the
▲
and
▼
keys
to select
your range and cell constant.
5.
Press the ENTER key
to confirm
your selection.
6.
Proceed to step 3 of section 6.6.2, or
press the
▲
and
▼
keys together to
return to measurement mode.
