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

HOLD SETUP 1) Enter Advanced set-up mode. Push ENTER key and scroll to
Advanced Set-up security code “22”. Push ENTER key. Controller
displays “tC”. Press ENTER key again. Controller displays “Pur” in upper
display and “tC” in lower display. Default is “Pur”.
2) Press Δ or ∇ keys to select between “Pur” and “Lin” temperature
coefficients. If “Lin” tC is to be selected, press ENTER key when
controller displays “Lin”.

3) If “Lin” is selected, upper display shows “2.10%”, while lower display
show “P.tC”. This option allows input of Process Temperature coefficient,
from 0 to 10%. Default is 2.10%. Use
Δ or ∇ keys to enter required
temperature coefficient value.
4) Press ENTER key. Next, enter the calibration solution temperature
coefficient value, “C.tC”, from 0 to 10%. Default is 2.10%.
