7 Advanced Set-Up Mode

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”.

7.1.1 Selecting Pure-water or Linear Temperature Coefficient

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 ∆ 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 ∆

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%.

5) Press ∆ or ∇ keys to input desired calibration solution

temperature coefficient.

6) Press ENTER key to accept.

7) Continue with additional Advance setup procedures or return to

Measurement mode by pressing ∆ and ∇ keys (escape)

simultaneously.
