Temperature Coefficient sub-function
This sub-function allows you to select the correct temperature coefficient for
optimum operations. For applications in the pure water or ultra-pure water industries,
simply select the “Pur” temperature coefficient option. For all other applications,
select “Lin” temperature coefficient. The controller allows further input of
temperature coefficient values, independently for the process and for the calibrating
solutions. Default is at 2.10 %.

Selecting Pure-water or Linear Temperature Coefficient
1) Enter Advanced set-up mode. Push the
ENTER
key and
use
▲
or
▼
keys to scroll to Advanced Set-up security
code “22”.
2) Push the ENTER key. Controller displays “tc”.
3) Push ENTER key again and use
▲
or
▼
keys to select
between “Pur” and “Lin” temperature coefficients.
4) If “Pur” tC is be selected, press the
ENTER
key and
controller goes back to “tC”. If “Lin” tC is selected, press
the
ENTER
key and proceed to step 5.
5) The upper display shows “2.10%”, while the lower
display show “P.tC”. This option allows you to input the
Process Temperature coefficient, from 0 to 10%. Default
is 2.10%. Use the
▲
or
▼
keys to enter the required
temperature coefficient value.
6) Press the
ENTER
key. Next, enter the temperature
coefficient of the calibration solution (0 to 10%). Default
is 2.10%.
7) Press the
▲
or
▼
keys to input the desired calibration
solution temperature coefficient.
8) Press the
ENTER
key to accept the value.
9)
Continue with additional Advance setup procedures or
return to Measurement mode by pressing the
▲
and
▼
keys (escape) simultaneously.
