6.6.3 Selecting conductivity (resistivity) value at 0 (4) mA
This parameter lets you choose a
conductivity (resistivity) value to be
equivalent to 0 (4) mA. Select the
lowest value of the conductivity
(resistivity) range that you want a
recorder or transmitter to detect.
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 a conductivity
(resistivity) value and the lower
display shows “r.0” or “r.4”
See bold figure at right.
4.
Press the
▲
and
▼
keys
to select
the conductivity (resistivity) value
equivalent to 0 (4) mA.
5.
Press the ENTER key
to confirm
your selection.
6.
Proceed to step 3 of section 6.6.4,
or press the
▲
and
▼
keys together

6.6.2 Choosing output range (4-20 or 0-20 mA)
This parameter lets you select an
output range of 4-20 or 0-20 mA. If you
select 4-20 mA, the minimum current
supplied by terminal 17 and 16 of the
17-way terminal block corresponds to
4 mA. If you select 0-20 mA, the
minimum current corresponds to 0.
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 output type
(0-20 or 4-20) and the lower display
shows “out”.
See bold figure at right.
4.
Press the
▲
and

keys
to select
your output range: 0-20 or 4-20 mA.
5.
