Low limit value
Sequence of operations 8. Keep stepping by pressing the ▲ button as long as you
see this sub-menu item:

( L imit 1 L ow Li mit =
= limit 1, low limit value). Here you can define the numerical
value by which the device will compare the measured
physical values.
9. Enter by pressing the
ENTER button.
10. You see this

on the display and the left digit is
blinking, indicating that the digit can be modify by pressing
the
▲ button.
11. Pressing the ▲ button you can increase the value of the
blinking digit:



,

,

,

,

,

,

,

,

,

, etc.
12. Pressing the ► button you can select the next digit.
13. When the left digit is selected, pressing ▲ button, the
sequence is:

,

,

,

,

,

,

,

,

,

,

,

, etc.
So you can set any value between -9999-99999.
14. After you have defined the value for the limit, press the
MENU button to exit from the sub-menu item, and you see
this:

.
15. When you don’t want to set hysteresis and you had
selected the

or the

modes there is no need to
do any further settings. For finishing the operation, please
go on from the point
Exit from the menu item.
Hysteresis of the low
limit
Sequence of operations 16. Keep stepping by pressing the ▲ button as long as you
see this sub-menu item:

( L imit 1 Hys teresis =
= limit 1, hysteresis) means: the hysteresis of the low limit
value. Here you can define a numerical value which
provides the hysteresis of the low limit value (L1.L.LI) by
having
added to and subtracted from it. Consequently,
the actual hysteresis is twice the value defined here.
