A total of up to 8 mathematics channels can be activated.

Note!

Settings only required if analogue measuring points are to be mathematically combined with each

other.

Set-up -> Signal settings -> Digital inputs -> Digital input x

Function On/off events

Designation Description of the function or measuring point name carried out with this input.

Designation ‚H' Description of the status when the control input is activated. 5 characters. Logically high = +12 to +30 V.

Designation ‚L' Description of the status when the control input is not activated. 5 characters. Logically low = -3 to +5 V.

Events text L->H Description for status change from low (-3 to +5V) to high (+12 to +30V).

Events text H->L Description for status change from high (+12 to +30V) to low (-3 to +5V).

Message window “Display+acknowledge”: message window shown in the display must be acknowledged by pressing the button (“OK”). It

contains the date, time and the corresponding event text L->H or H->L.

“Do not display”:

No message window is displayed. The events are, however, still saved in the events list. The event is described with “L-

>H” or “H->L” (alternatively event text L->H / H->L, if text has been entered there).

Copy settings Copies the settings of the current channel into the selected channel (including limit values). Both of the last positions of

the target channel's designation are replaced with its channel number.

Tip:

Makes device setting easier, if the same settings apply largely for several measuring points.
