Setting the reference temperature

The setting is only effective if the linear or nonlinear temperature compensa-
tion is switched on.

You can set the reference temperature as follows:

Setting menu of

the reference

temperature

1

Open the setting menu for the cell constant with 

<

C

>

.

The display shows the setting last selected.

2

Open the setting menu for the temperature compensation with 

<

T

>

.

The display shows the setting last selected.

3

If necessary, select the 

nLF

 or 

Lin

 temperature compensation with 

<

ß

_

>

.The display shows the reference temperature set last.

4

Using 

<

, switch between 

tr20

 and 

tr25

.

tr20

 = reference temperature 20 °C

tr25

 = reference temperature 25 °C

The adjusted reference temperature is used.

5

Confirm the setting with
