7 ADVANCED SET-UP MODE

7.1 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 ultr-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 %.

7.1.1 Selecting Pure-water or Linear Temperature Coefficient

1) Enter Advanced set-up mode. Push the ENTER key and

scroll to Advanced Set-up security code “22”. Push the ENTER

key again. Controller displays “Lin” in the upper display and “tC”

in the lower display.

2) Press the ∆∆ or ∇∇ keys to select between “Pur” and “Lin”

temperature coefficients. If “Pur” tC is be selected, press the

ENTER key and controller goes back to “tC”. If “Lin” tC is selcted,

press the ENTER key and proceed to step 3.

3) 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.

4) Press the ENTER key. Next, enter the calibration solution

temperature coefficient value, from 0 to 10%. Default is 2.10%.

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

solution temperature coefficient.

6) Press the ENTER key to accept the value.

7) Continue with additional Advance setup procedures or return

to Measurement mode by pressing the ∆∆ and ∇∇ keys (escape)

simultaneously.
